I've got them on my 16v, I only really got them so I could go stupidly low though.
They replaced a set of 40mm Koni shocks and springs, which were a bit soft for my liking.
Tbh I was very impressed with the difference the coilovers made to the car, reducing body roll unbelievably compared to the Koni's. Fair enough there is very little dampening, but feck me does she stick to the road through the corners (when I didn't have her stupidly low).
I am now totally sick of having the car sitting on the deck though. It's destroying the car by rattling everything loose, handles like sh!t and is just plain uncomfortable.
I will be raising her back up to a more practical ride height soon, but am pretty happy with the performance of the coilies overall.
