I have Skunk 2 coilovers on my GSR. If you go the Skunk 2 route make sure to get the Skunk 2 camber kit as well. Guy (thats his name) at Automotive Engineering can help ya out. My coilovers are kind of bouncie and squeak a little somtimes. But other than that no issues with them and I'm happy I got 'em. I prefer Skunk 2...just my .02 cents.
