I had the k-sports and they were pretty good. But the shocks didn't have enough dampening to handle my agressive cornering considering the weight of my integra. They worked perfectly on the lighter civic where they were a good match. I replaced them with Apex-i N1 Pro's. They were designed from the N1 endurance race in Japan. They have 60mm shocks up front and 50mm in back with dual valves. Huge shock! More dampening than I could use. Only at about 30% dampening and its still a very firm ride. But where these coilovers really shine is in high speed cornerning where most of the other coilover brands fail. If you can find them at a discount get them. Otherwise they are a expensive at $2600 suggested retail. But I was able to find my set on ebay for $1300 from a guy who brought them back from japan thus cutting out a great deal of the middle man cost and passing his savings on. Check ebay for these coilovers. If you can't find them there the cheapest I've seen them for sale online was $2100. Wooo Haaaa.
