been running the bilstein pss10 on mine for the past 10k miles, got them for a good price from julian at Balance c£1100.
These are my first coilovers i have had for any of my cars so difficult to compare to anything else, but been really impressed with them, handling is sharp and smooth when driving on good roads, but you really feel the bumps and dips in the roads and can be a bit much for the gf on long drives but I like it.
simon at amd in woking who put on my revo map and then took the car out to
test thrash it, asked me when he got back what they were as was very impressed with them, they normally fit kw there, but i've never driven a car with kw on so couldnt comment
easy to adjust them,no need to jack the car up, but it does make it easier with the rear shocks, the fronts you just turn turn the wheel and adjust the nobs. only ever adjusted them once though when I went to the pod to tighten up the rear...
sure either the kw's, ast or bilstein all give good performance
I went with bilstein as been playing GRID racer on ps3 alot so all their advertising on the game must have worked
