I was on the stock setup for 3k miles. Then RCE Yellow on OEM dampers (~9k miles). Eibach Multi-Pro R1s (~250 miles) and now RS*Rs Sports-i. I also have about 35 miles (test drive) on a windy/bumpy road with the KW V3s. Thanks to my mate for letting me borrow his car with them.

In terms of comfort I would rate the RCE Yellows on the OEM dampers BETTER than the Multi-Pros R1s and the KW V3s but the V3s had better damping but much too firm for me (hope that makes sense). However, the RCE Yellows on OEM dampers couldn't handle big bumps (high speed compression) very well. The R1s and the KWs are probably better for a track guy who understands bump/compression settings and has the patience to dial them in. They are also noisy with the Eibach's being the noisiest. I prefer the RCEs over these two coilovers.

The RS*Rs are a more sophisticated set. The adjustment range was good. I think they did a good job finding the crossover point between bump and rebound and fixed it in one easy to access adjustment knob. I wouldn't say they are an all out track ready setup. They weren't designed to be because they were designed to be a true "Sports" suspension imo. They're more comfortable than stock in most cases but on big bumps the stock suspension was slightly better able to absorb due to the added shock travel. The 86 has ridiculously short shocks and really short suspension arms. You need a well tuned damper to be used because the car is quite sensitive.

I don't want to get into the technical details but let me suffice to say.. the RS*Rs were the best I could find for the price. Every other damper in that price range is no comparison if you're looking for a quiet (don't take this for granted!!!), sophisticated, sport damper. If you're going to be at the track say more than 50% of the time.. get something else.

Think of this way... it's like getting a BMW "M" upgrade option when you get these dampers. The M3 isn't a serious track car but achieves a great balance between street and track.

good luck
