Shows removal of OEM rear control arms and installation of Go-Fast Lab's anti-bumpsteer rear control arms.

 

Mike, this is good info. I'm adding this to the FAQs.

 

Also working on SS brake lines and brake ducting. Expect to see those writeups when the work is finished.

 

What is the purpose of the new control arm? Is it to "fix" the suspension geometry of a lowered car? If so, how do you know the optimum length?

 

I just read about it in the Market Place, but it still isn't obvious how you determine the right length.

 

Your alignment tech will set the length for you. Assuming you go to someone experienced enough. My car is not lowered, but I was going to higher rear camber. Even with the extra length extension, the alignment tech ran out of toe at 3 degrees camber. Apparently the lower arm became the main limiting factor.

 

I guess I was WAY off. I thought you would want to SHORTEN the control arm to fix the geometry of lowering it. I also thought there would be some mathematical aproach to figure out how much to shorten it based on how much it was lowered. I don't know of any alighment shop that I would trust to "wing it".

 

I shopped around for a place that is used to working on track cars and race cars. The local tire shop probably wouldn't be the best bet.
