PA will always be in the lead concerning units sold. Dan designed this unit from the ground up based on what he liked from other K members and what he wanted from his own design. PSR's K-member setup concentrates on 3 things: strength, weight, and clearance/fitment.
IMO this K-member really shines in the turbo department with a non OEM exhaust manifold, and this is one of the top three reasons it exists. This is where the K-member will make its name for itself. There are currently 6 turbo cars being done at the shop with the PSR K setup, and a couple of local non-turbo cars with the unit as well. In addition, Stormin Norman and Sambandit are also running PSR units. Finally, it's also holding up in excellent fashion to the Silver shop car slamming it up and down.
You need coil overs, MM or equivalent caster camber plates and PSR arms to run the PSR K-Member.
If you'd like, On3Motorsports (PSR's parts department) can take care of you in w/e decision you make. 602-269-0029 ask for Dustin and tell him I (James at PSR) sent you.
