Koni dampers with H&R springs for the P11...

I had these fitted on my P11 GT.The Koni and the H&R go together very,very well.The Konis are adjustable (off the car) for stiffer/softer damping.I had mine set with 1 full click on the back and 1/2 click on the front.This seemed to be the best position for my driving style.
The H&R springs will lower the car between 35-40mm.This is quite a hard ride,but does handle very well and I think it is a good compromise.
I never had any problems with this set up at all and was very reliable.
Both these kits are available from any decent performance parts shops.

Price of this sort of set up will cost you around £450
