Perrin Antilift Kit
 

I recently fitted a Perrin antilift kit to my MY00 WRX. The handling difference is amazing with much crisper turn in on the corners, less understeer and better acceleration on launch.

Accompanied with all of this is about an 80% increase in percieved road noise. Due to the type of bushings on the kit there is much more road vibrtion / noise now.

What I am also hearing and I am not sure if it is common is a CLUNK on hard acceleration or braking. This is comming from the control arm moving slightly against the bushing.

I installed all the parts myself and torqued all the bolts to their relevant specs so nothing is loose in there.

I get the CLUNK if I "pop" the clutch in first depress it again . The same if I do it when in reverse gear.

Has aanyone out there experienced this issue?
