Bye, bye wheel hop!
Today I added the Steeda Rear IRS Subframe Support Braces and Bushing Support system. It really made a difference stiffening up the suspension. I will install the Steeda Vertical Links next week. Bye, bye wheel hop!

Tracks like a go kart now
On my previously stock GT non-PP i had a odd sensation while cornering that could best be described as a "rubber-band" feeling. I believe it was compliance of the subframe bushings. It was unnerving. Felt like the start of the tires breaking loose - but it wasn't. I installed the Steeda rear IRS bushing support kit and the IRS braces and the sensation went away. Much improved cornering afterward. I was inspired by the improvement so I added the Steeda springs and swaybars. Tracks like a go kart now.

Still love it
I've owned a base ecoboost and now I own a performance pack ecoboost. I have steeda irs frame stiffeners and the front g-trac bar. I had them installed on both cars and the pp car vs the base is a WORLD apart on the way it handles. Yes the ride isn't as soft as the base but it doesn't bug me, I still drive the car daily and still love it. I have the steeda jacking rails on the way and after that it will be one of the suspension kits next. I want the car to handle on rails. It's just the way I feel about it. Hope this helps

One of the biggest improvements to the handling of the car
One of the biggest improvements to the handling of the car is definitely the Steeda goodies all thanks to David here on the forum. He helped me so much picking out everything I should upgrade for all of the suspension parts to make this a great daily driver but also be able to take turns comfortably at high speeds and put the power to the ground. One of the first Steeda upgrades Slammered threw on for me was the Front/Rear Sway Bars and the IRS Support Brace and damn did it make a pretty damn noticeable difference in turning. No I don't track this car as of right now but the closest I get to taking turns and curves is off ramps from the highways and I've done decent speeds coming through those turns. The sway bars help keep the car planted and definitely boost the handling capability that the IRS already provides. I also installed the billet mounts and they look damn good with the blue sway bars and definitely are top notch quality over the stock mounts from Ford. Wheel hop has been one of the most notorious things the S550 platform has encountered with the new IRS system. Wheel hop is a "No no" and Steeda's IRS bushings are definitely the first step to knock out way more than 50% of the notorious wheel hop. When taking the bushing out of the box and taking a peek at my new goodies, I was amazed of the quality that is put into the manufacturing of the parts Steeda offers. IRS Bushing from Steeda is a must if you're looking to eliminate more the 50% of the wheel hop. It's great quality and definitely helps put the power to ground. When hitting it and shifting from 2nd to 3rd it's a whole new feel and it just takes off.

This is the way the car should be with the PP
Since I was going to have the car up on jack stands in my driveway, I figured I'd do just about everything at once. Installed the Steeda IRS subframe bushing supports, alignment inserts, differential bushing supports(black), transmission bushing insert, and the Steeda shifter base bushing bracket along with the FR touring cat back. I had to have the upgraded bushing in the knuckle done at the Ford dealer. The bounce is gone! This is the way the car should be with the PP.
