We spent countless hours fiquring out where the S197 Mustangs could benefit most from chassis stiffening. Here is the end result. There are several vendors out there treating your S197 like it was an old fox body, making large braces for areas that are not weak on your S197 and that add a lot of unnecessary weight.

We took a strategic approach with Steeda's 3-point torque box and frame rail braces. These braces are made from 4130 Chrome Moly material. This material is twice as strong as mild steel and half the weight of mild steel.

These braces are compact and light weight. They are much lighter than the unnecessary braces many competitors offer and specifically designed for the needs of the S197 Mustang. They tie together the inner/outer frame rails and the rear lower control arm mount. One of the few areas on the S197 that could use additional bracing.

Our braces are silver powdercoated and come with mounting hardware. They can be bolted with our supplied hardware or welded in place for maximum effectiveness.

Note: Does not fit convertible Mustangs. Also, will not fit Boss 302 Mustang, or any Mustang equipped with the Boss 302 quad-exhaust system.

Product Reviews

I had these welded in. Anyone planning on purchasing these and just throwing them under the car with bolts shouldn't. They will do nothing but increase vehicle weight unless you weld them.. They solidified the vehicle chassis GREATLY. These are the best on the market without question. Superbly built and quality materials. Other subframe connectors from the competition are heavier, they are bigger, they are not engineered with the Mustang in mind. Purchase this product if you are considering it.

I purchased this honestly not expecting a noticeable difference, it was more of a piece of mind item. After receiving and installing it, I couldn't be happier.

The design is fantastic, it ties the frame rails to the lower control arm mounts- A fantastic addition when you're already swapping out your lower control arms. Super lightweight and a huge combined improvement in wheel hop and straight line stability. They required a little force to get the bolt holes lined up, but the manual warns about this, and you should weld them in eventually anyways.

Absolutely gives your ride a better sense of handling and confidence in the turns.

I knew I wanted to brace the underside of my car, there are a lot of options, but I was looking for something that would add the least weight for the benefit it yielded. This set of braces did exactly that, without welding them in I can already tell a difference. The points that it mounts to are ingenious, I particularly like the way it braces the lower control arm mounts on the chassis.

Installed this today....took 20 mins per side. No more rattles, car handles great. Just welded it in. Easy instuctions, Thanks for another great product Steeda!!

The only thing that was missing from the G-Trac Suspension package on my 2006-021 Serialized street fighter. Absolutely perfect installation. With all the stuff under y car, it is glued to the road. I could not ask for any better friends than my friend Sal and STEEDA. Many thanks and God Bless. From a very pround owner!

I put a lowering kit on my car and the extra firmness put a few rattles into the car. These braces bolted right up as advertised. I recommend an air wrench if you can get a hold of one. Bolted on, I didn't notice much difference. After about 2 weeks I got them welded in and now I can tell. The majority of the rattles/squeaks are gone now from the rear of the car and the car overall feels more solid. As a bonus, the braces make great jacking points.Great product!

Very light weight and apparently strong brace. Very easy to install (bolt in) and I'm hoping to get it welded in shortly.

I got the frame rail and torque box brace and couldn't believe how fast and easy it was to installed. The instructions were right on. It did quite some rattling noise.

This should be one of the first improvements done to the car! It tightend everything up so much that I no longer have any creaks or squeaks around the interior area of the doors. The rear is firmly planted at the drags strip, but I really noticed the difference in the cornering abilities. Bolted right up, then had them welded inplace.
