Okay, I was planning on getting the KTS coilovers from SPL, but a couple of my friends are suggesting Koni Yellows with something like 450/400 eibach race springs with Ground Control sleeves. The KTS coilovers are 448/336. I'm going to be doing road racing maybe once a month and a lot of canyon driving with the occasional parking lot drift. Comfort is of little concer to me and they are both priced similarly, so it's not a big deal. Koni also has an enticing warranty. My question is which would be better for me? I was really leaning toward the KTS, but after talking with a few of my friends, I would like some other opinions.
