I saw these in the Summit catalog. Anybody ever order these? I don't really know what to look for I just know that I need SFCs really bad. With these do you have to move the rear springs more inward or do any other modifications to your car to get them to fit? If these ones don't have a good name then can somebody tell me which ones are good and don't require a lot of modification to the car? Thanks to anyone who replies.
