Well i have had two sets off adjustable lower arms in my Rs2000 Turbo.

Ones similar to the area six ones and some zoo motorsport ones. And what a difference they make.

I had to put standard ones back on for a couple of weeks while waiting for the Zoo motorsport ones to come, and could not stop the car wheel spinning in first and second. Even with a quaife diff.

In my opinion well worth the money!
