To start off I constantly break traction every time I floor my car, wether it's from a stop or even when my cars in full motion. I do have very good ,sticky new potenza tires btw. I was told rear upper and lower control arms will help me stay "planted" when going fast. Any opinions or suggestions?? Thanks

 

I can give you my opinion, but its the more expensive route.

Torque arm and panhard bar are the absolute best pieces you can get for handling and traction. The combination of the two allow you to remove both upper arms. Then get tubular lower arms and you will hook up very well.

Tubular uppers and lowers will help a good amount, and is cheaper. But not the best.

 

It's a combo of proper struts/shocks, weight transer, gearing, chassis stiffening, ect. Yes, aftermarket rear upper and lower control arms will help. Also, "new edge" stangs accelerate better with drag radials/slicks. I have a full bolt on 2v. Auto with 4:10s. I have 285/35/18 Nitto NT05 and still have trouble "hooking up". Even at 35mph.
