You're talking about the baseline suspensions stuff right? I bought the upper arm kit from Kevin for my car a few years back but couldn't use it. My anti-rollbar hit the tabs on the bar that joins both sides together at the top of the rear end. Team Z offers the same type of set up. If I had the Team Z kit it would've worked since the tubes slide together. http://www.teamzmotorsports.net/products.html#suspension
