About 1.5yrs ago I bought an '07 GT500 that was mostly stock and had 17k mi; just a CAI, Tune, Pulley, and Axle Back. Wheels & tires are 19x10.5 '10 GT500 style wheels with BFG G-Force Sport 285/35/ZR19
Before buying the Shelby I knew the suspension on these was basically junk & had planned to completely overhaul it. After a lot of research I decided to go full BMR.
I cannot believe how terrible it was from the factory. Wheel hop was atrocious, the car was so twitchy in the rear end; it was a real fight to keep it straight. Also on a hard corner the understeer was so bad; it's like the whole front nose would pitch over and the car just wanted to plow through turns.
The only car I've had that was worse than the Shelby was my '03 Z06. I swear that car was so tail-happy it just wanted to do donuts everywhere.
I could never get floored in 1st gear, and only a couple times could I get floored in 2nd.
The final straw was my wife has a 2017 Daytona 392, and from stoplight to stoplight she would nearly always beat me because I couldn't hook up at all.
So I threw a bunch of BMR mods at it. Also did a bunch of other mods such as some appearance, Double Din head unit, and a Big Brake Kit (I'll make another thread about the brakes). BMR:
- Adjustable rear sway bar
- Adjustable panhard bar
- Adjustable upper control arm w/ Poly bushings
- Adjustable Upper control arm mount
- Adjustable Lower Control Arm Relocation Brackets
- Drag Springs
- Panhard bar brace
- Adjustable sway bar end link
- 5-way adjustable sway bar
- Lower Control Arms w/ Poly bushings
- Drag Springs
- Strange 10-way adjustable struts
- Stop Tech Stainless Steel brake lines
- Viking Double-Adjustable rear shocks
- Ford Racing Aluminum Diff cover
- DSS Aluminum Driveshaft
- MGW Shifter
The BMR parts fit great- very precise. The only problem I had at all was the bolts were too short for the LCA Relo Brackets with the Sway bar brackets. Kelly at BMR was fantastic in helping me get this sorted out with new bolts.
I was pretty skeptical that all these mods would make much difference. But I was wrong. Very wrong.
All I can say is WOW. It's like a whole new car. It's almost effortless to go fast now. I can get on it and the car just hooks up and goes straight with no-drama. I can stomp it in 2nd gear and it goes.
I didn't change the tires because I really wanted to do an A/B comparison of how much of a difference just the suspension made. Once I burn through these tires I plan on getting something much stickier (Toyo R888R?)
Now that I have traction it's time for more power.... I have a few other car projects in the pipeline but hoping in ~2yrs to start the next phase of the build which'll be a VMP Gen3R
