I was checking out the rear control arms made by Addco in Summit. Has anyone tried these or know anything about them. My car is set up for drag racing. Mostly guys around here stick with Hotchkis, but I'm willing to try these for half the price. Knowing my luck I'll snap em in half. I plan on using QA1 shocks and pretty much want my ride to squat when I launch. Any advice would be helpful, I know you get what you pay for. Peace.
