Ive been talking about different control arms. I have heard of wreacking my torque boxes. I seem them on ebay for Fox bodies. Do I need to get these or what?
You want the ones with a poly bushing on one end, and a spherical bushing on the other, to prevent bind. Double poly bushings will wreek havock on your torque boxes, and from what i have read will present some crappy handling characteristics.
I've heard of some people's boxes tearing with stock vehicles. I have never had any trouble with mine but some places sell replacements. Here is a link u might want to try http://www.wildridesracecars.com/chassis3.html
If you plan on racing the car, which I'm sure you are, you should ALWAYS (at least) weld the torque boxes. You really should reinforce them. Launching a car hard on slicks, or any sticky tire, do lots of chassis damage over time.
