Evan Smith Track Tests Steeda’s 686 rwhp 2015 Mustang GT

Evan Smith said it himself, “This Mustang eats up the track and leaves you plenty of performance for the street.”

The team at Steeda Autosports has been hard at work developing new parts for the S550 platform and we’ve turned our Triple Yellow Q650 2015 Mustang GT into a corner-carving track monster. Pumping out 686 rwhp on 10 psi and pump gas, it’s a force to be reckoned with both on and off the track.

Yellow-Front-3qrtr-sunset

“Our objective with the Q650 and our Q-series of Mustangs is to build a track-ready car that outperforms much more expensive cars for far less money,” said Dario Orlando. “We manufacture and sell our own parts so you can purchase a complete car with the Steeda package installed, or add the parts to your existing Mustang. For the 2015, we first built a mockup of the front and rear suspensions. This allowed us to analyze the suspension arrangement and note the areas of concern as they relate to high performance. We’re looking to satisfy the performance-minded enthusiasts who wants a fast, capable street car that is ready for the track.”

2015 Mishimoto Ford Mustang EcoBoost Oil Cooler

When we heard about Mishimoto’s 2015 Ford Mustang EcoBoost Oil Cooler, we had to put it on our Steeda 2015 Competition Orange EcoBoost Mustang!

The entire installation process took about 2 hours – not bad. Especially when you know your turbocharged 4-cylinder engine won’t overheat with this oil cooler as it pumps out over 300 horsepower. This Mishimoto 2015 EcoBoost Oil Cooler is a direct fit, which makes installation a breeze.

Mishimoto offers their oil cooler in either silver or black and they also give you the option to choose between a billet aluminum oil sandwich plate or thermostatic oil sandwich plate. For our installation, we went with the silver oil cooler and the thermostatic oil sandwich plate since we wanted a faster warmup at startup.

mishimoto package

All of the parts needed for the installation were included:

  • 3 Application-Specific Mounting Brackets and Spacer
  • 19-Row Oil Cooler
  • 4′ 3.5″ Stainless Steel Braided Hose with 45° and 120° – 10AN Fittings
  • Oil Sandwich Plate
  • 3/4″ x 16 Stainless Steel Sandwich Plate Adapter
  • 2 M20 x -10AN Straight Fittings
  • Mounting Hardware Set

First we lifted our 2015 EcoBoost so we could remove the undertray. After that was completed, we used a flathead screwdriver to remove the eight pop clips that fastened the plastic air diversion cover.

mishimoto bumperImage of the front bumper hardware removed.

The third stage in this installation process was removing the front bumper. This stage consists of removing the front bumper hardware which are four pop clips, six 8mm screws and two 7mm bolts that are near each headlight behind the fender liner; and unclipping the bumper and six wire harnesses for the turn signals, headlights, and fog lights from the vehicle.

mishimoto wiresImage of the turn signals, headlights, and fog lights wire harnesses being detached.

Next we removed the air dam, the air shutter arm and all other connectors that connect to the air shutter motor and the ambient temperature sensor. We also removed the lower grill shutters as well as the arm that attaches the lower shutters to the upper shutters. This gives us the room we need to install the Mishimoto 2015 EcoBoost Oil Cooler.

We then removed our oil filter so that the Mishimoto sandwich plate can attach in place by using the 3/4″ x 16 Stainless Steel adapter.

EcoBoost Oil FilterThe 2015 EcoBoost oil filter before being removed.

To avoid any unwanted friction, we lubricated the O-ring on the sandwich plate before fastening it in. Once the sandwich plate and straight fittings are all fastened and secured, we attached the stainless steel braided fittings with the 120 degree fittings connected to the sandwich plate.

mishimoto sandwichMishimoto oil line fittings and sandwich plate before the oil filter is reattached.

We then lubricated the O-ring and reinstalled the oil filter. Next we snaked the oil lines so that they were next to the steering rack. The shorter oil line with the 45 degree fitting was routed into place first since it was the first to be attached to the oil cooler.

We detached the front support bars in order to attach the oil cooler with its application-specific mounting brackets.

mishimoto-9One of the two top application-specific mounting brackets.

After the oil cooler was mounted, we attached the 45 degree fitting and the longer hose with the 90 degree fitting to the oil cooler. We then started reattaching all of the parts we removed during the install!

After our 2 hour installation, we couldn’t wait to test it out on the road and track. The Mishimoto 2015 EcoBoost Oil Cooler reduced our oil temperatures by up to 35+°F. The oil cooler receives the most airflow by being mounted at the front of the vehicle which cools the engine’s oil faster and more efficiently, which is always a good thing with a forced induction setup.

Track Guys 2015 Sebring Sensation

The Track Guys have been hosting performance driving education events at Sebring International Raceway since 2001. And this past 2015 Sebring Sensation gave advanced and beginner performance drivers a chance to fine tune their skills out on the famous Sebring International Raceway. All the drivers and their cars were divided into four groups depending on their skill level, this gave everyone ample amounts of time out on the track.

Sebring Sensation 2015

Performance drivers were given the opportunity to compete against their fellow class drivers in the Steeda Hot Lap Challenge. This timed race was also divided into groups of stock, modified and race – which were all timed by transponders.

Customers and Mustang enthusiasts alike had the opportunity to feel superior power and performance by riding in one of the many Steeda Mustangs that attended the event. However, Steeda was out at Sebring for an additional reason. We had our minds set on testing our 2015 Steeda Q650 Vortech supercharged Mustang GT loaded with our suspension upgrades out on the track.

Yellow-Front-3qrtr-sunset

Since Q4 2014, we’ve been hard at work to create this build list. Our dedication and premier engineering was solidified after testing our 2015 Triple Yellow Mustang GT at Sebring the last weekend in May. Pinpoint handling, quick steering response, planted suspension, and extreme horsepower were just some of the key highlights our Steeda Mustang brought to the raceway.

Stop The Hop With Steeda’s 2015 Mustang Differential Bushing Inserts

Here at Steeda, we’ve been hard at work developing new upgrades for your S550, and we’re really excited about our two innovative differential bushing inserts!

Let’s first introduce the Adjustable Urethane Differential Bushing Insert System! When our engineers sat down to design this kit, we had to come up with a way to increase performance without sacrificing an ounce of drivability, all while keeping the car quiet.

Unlike our competitors’ kits that will absolutely increase NVH (noise, vibration, harshness), take 3-4 hours to install and force you to permanently modify the rear IRS suspension with a sawzall, Steeda’s does not! Our kit installs in under 1 hour, adds ZERO increase in NVH, is adjustable and can be easily removed – it simply doesn’t get any better than this!

Minimize pinion angle changes, increase traction, eliminate wheel hop and differential deflection with Steeda’s new kit. Made from high-strength urethane to our exact specifications and durometers, our kit comes with 2 different bushing options – red ‘street’ 80 durometer bushings and our black ‘performance’ 90 durometer bushings. Both bushing options will increase performance with no increase in NVH, a Steeda-exclusive.

Steeda’s kit adds the strength and support the OEM bushings need to perform the way our customers intended. Once again, this is not a permanent modification – there is no drilling, cutting or pressing required. Simply loosen and remove a couple bolts and this kit installs in less than 1 hour. Bushings are included for both the front and rear differential mounting locations in addition to grade 10.9 hardware with zinc-plated washers.

steeda differential bushing inserts - urethane Steeda S550 Mustang Adjustable Differential Bushing Insert System – Urethane (2015 All)


We also knew we needed a kit for the hardcore racers out there! So our Aluminum Race Differential Bushing Insert System is made in-house from billet 6061 aluminum, this is not a permanent modification – there is no drilling, cutting or pressing required. Simply loosen and remove a couple bolts and this kit installs in less than 1 hour. Aluminum bushings are included for both the front and rear differential mounting locations in addition to grade 10.9 hardware with zinc-plated washers.

Please note: This is a race-only part. It will increase NVH and gear noise.

Aluminum Race Differential Bushing Inserts Steeda S550 Mustang Race Differential Bushing Insert System – Aluminum (2015 All)


For those of you that would like a complete one-stop shop street to full race kit which provides interchangeability options for both urethane and aluminum bushing inserts, we have the perfect combo kit. For the small amount more the Steeda kit will cost you, you will be saving so much more on labor (over 3 hours) when comparing to competitors’ kits. Here’s a link to our combo kit 555-4442.

Thomas Ellis and His Steeda Equipped Mustang Take Gold

On April 6, 2015 at Homestead Miami Speedway, the Trans Am Series held two races with a total of 65 participating cars. The first ever Trans Am Muscle Car Challenge was held by the TA2 class, independent from the TA and TA3 100-mile Trans Am race.

Thomas Ellis led the class to the winner’s circle with his No.00 Steeda equipped Ford Mustang in the TA3 American Muscle Group. Following Ellis on the podium was Todd Napieralski in a Chevrolet Camaro and Christopher DeSalvo in a Ford Mustang.

Boss 302S Steeda Mustang

In the American Muscle Group, Ernie Francis started the TA and TA3 race out in front but was forced into the pits during the early laps, forfeiting any chance of victory. DeSalvo progressed to the lead but was quickly overcome by Ellis during lap four. By lap eight, Napieralski passed DeSalvo and all three maintained order until finish.

Ellis’ win showcases Steeda’s superior engineering and high-quality products being tested at the track under grueling and competitive race conditions.

2015 NMRA Bradenton – Steeda-Equipped Racer John Urist Sets Class Record!

We had a great turnout this weekend at the 2015 NMRA event at Bradenton Motorsports Park. There were plenty of racing categories such as the Street Outlaw class and the Edelbrock Renegade class, although one of our favorites was the True Street class which was actually started by Muscle Mustangs and Fast Fords and Tremec back in 1995.

nmra14

If you’re looking to prove your True Street Mustang on the track, the event begins with a 30-mile escorted cruise with other True Street racers, passengers and crew members which serves the purpose of proving street-worthiness of all cars competing in the True Street class. Once the 30-mile cruise is complete, all racers head to the track for three back-to-back passes – racers aren’t allowed to work on their cars prior to racing, which also proves street-worthiness.

One of the highlights for Steeda was seeing John Urist qualify number one with a 6.86 pass at 204 mph – the quickest pass in class history! Urist had stiff competition on his heels with the next competitor making a pass at 6.88. The cloud cover broke on Sunday, and Urist’s Steeda-sponsored Mustang worked as expected to assist in running back-to-back 6.90′s to take the win! Urist is heading to the Atlanta races to continue showing the world what it takes to be a champion!

Steeda’s All New 2015 S550 Mustang Bumpsteer Kit

If you have substantially lowered your vehicle, chances are you have introduced bumpsteer. What is bumpsteer? Bumpsteer relates to changes in toe caused by suspension movement.

Every car has bumpsteer, however when you lower the vehicle you increase the amount of bumpsteer that occurs – if this becomes excessive you will begin to notice some unwanted vehicle driving characteristics.

Excessive bumpsteer is undesirable because it means the suspension is steering the car instead of the driver. If your car is lowered and has tracking issues and less predictable steering behavior, you need a bumpsteer kit!

You shouldn’t have to sacrifice your steering when you lower your vehicle, so at Steeda we’ve designed bumpsteer kits that will allow you to correct your suspension’s geometry and can do so without requiring you to drill or modify your vehicle spindle. In addition, our bumpsteer kit makes a great service replacement for your worn out, high mileage outer tie rods even if you do not have excessive bumpsteer issues.

Check out our installation video featuring our newly designed 2015 S550 kit:

If you want to refresh your outer tie rods and improve your steering, you can purchase our 2015 Bumpsteer Kit here: http://www.steeda.com/steeda-s550-mustang-bumpsteer-kit-2015-555-8133/

Wheel Hop Solution: Steeda S550 IRS Subframe Bushing Support System (GT, V6, EcoBoost)

We’ve been extremely busy with product development over here at Steeda – our main focus has been a turn-key wheel hop/IRS subframe solution for the S550 and we hit the nail on the head with our IRS Subframe Bushing Support System!

Made from CNC machined, 6061 aluminum, our bushing support system gives the rear end a much more solid feel with no increase in NVH at all. The Steeda IRS subframe bushings eliminate rear subframe movement notorious in the 2015 Mustang GT, EcoBoost, and V6. A stiffened subframe allows the car to increase traction to the rear wheels and helps eliminate wheel hop.

Our Steeda IRS Subframe Bushing Support System (Part #: 555-4437) is very easy to install with basic hand tools and does not require any permanent modifications to the car.

Steeda Kit Pros:
- Helps reduce wheel hop by eliminating subframe movement, therefore giving you much better rear suspension compliance
- No permanent modifications are necessary
- Easy, 30 minute installation, can be done on jack stands in the garage
- Our kit doesn’t increase NVH at all
- Can be removed or installed in less than 30 minutes
- Completely eliminates over ½” of travel in the factory IRS subframe
- Doesn’t require a rear end alignment
- Lifetime warranty
- Track-tested at the drag strip and the road course – we are not just straight line people

Competitors’ Kit Cons:
- They make you replace the factory bushings completely with urethane or solid aluminum
- A complete removal of the IRS subframe is required; this not only takes several hours, but it’s not the easiest job for a ‘do it yourselfer’
- Other kits will increase NVH if using solid aluminum bushings or very hard urethane
- Takes hours for installation
- Although other kits may reduce wheel hop, an increase in NVH is not desirable
- You will need to re-align your car if you replace the bushings that locate the rear subframe
- No bushings carry a lifetime warranty, they will fail eventually

We’ve attached some product photos for reference – also, this kit is readily available! Steeda’s IRS Subframe Bushing Support system greatly reduces wheel hop while virtually eliminating all IRS subframe movement. When these pieces are used in conjunction with our other Steeda rear suspension components, wheel hop and subframe movement is eliminated – stay tuned as these additional rear suspension pieces will be available in the next couple of weeks.

Again, this is not a permanent modification! It can be put back to stock in under an hour as it’s very easy to install.

Why IRS subframe movement must be eliminated…

As you can see in the video, when completely stock, the entire rear IRS subframe assembly moves around under acceleration, braking and even more so when bangin’ gears. This is a major problem because every single rear suspension piece is connected to this subframe. So as it’s moving and vibrating, so is the rear sway bar, toe links, integral links, camber arm and lower control arm. They are all moving around violently as well so it makes it very hard for your suspension to ‘work’ and keep the tires planted on the pavement for traction. The assembly is basically fighting the car and not allowing for the suspension to work the way it was designed. This causes unwanted changes in camber and toe which will lead to unpredictable traction and control, resulting in handling issues. Steeda’s simple kit eliminates this. PERIOD.
