I apologize for any delay in getting a call back....things are a little crazy with SEMA follow up and the ATS acquisition. Sorry about that! The things I'm looking for in a control arm kit are: strength of the arms, Our arms are made of DOM tubing, and are probably overkill in any application short of Baja 100 cars...our "shop car" with it's cast iron big block has been relentlessly thrashed on track and autocrossed, with no issues whatsoever. no change in ride height, No change in ride height whatsoever no fouling on the other front end components, latitude to change the alignment specs to something more aggressive for track use but still allowing me to dial it back for street driving, and technical support if needed. Our arms do not rule out any factory components, and allow plenty adjustments for whatever driving situation you find yourself in. Technical assistance is a phone call away, and chances are you will end up talking to an owner, so all info is straight from the horse's mouthThere are a couple of issues with second gens starting with GM changing the bolt size between 70-81 on the lower control arms. Not sure how many control arm manufacturers are taking this into account with their kits? Where the spring cup is located in the lower control arm will affect ride height. Some companies offer spring seats/shims We offer urethane spring isolators with our arms while some do not. Also are the manufacturers pivoting the whole steering knuckle to increase caster or just pulling the top of the knuckle farther backwards which will affect how the wheel/tire looks sitting in the wheel well? Will the control arms affect track width? The track width will not change, and the design of the arm will move the wheel back about 1/4" in the wheelwell. These are all things I'm trying to get sorted before making a purchase.
One additional feature, our arms use Acetron®, an non-porous version of the same material used in Delrin bushings. A non porous material provides superior consitency and strength.

Thanks for your input and good luck with your project
