I have to say, the FTBR bushing kit is a must for any and every cobra. I've had nothing but great experiences with the product and staff. I ran into a few problems with the installation (removing poly bushings), but bruce helped me out a lot through the process and is all around a great guy. On to the success. Wheel hop was once a huge problem, especially with street tires at the track. With the bushings in, absolutely none. The car hooked great at a 3200 rpm launch and pulled hard from there. I expected a little hop with the sumis, but if anything, I'd just spin a bit. The thoughts of my half-shafts popping are no longer existent. Props to Bruce, Steve, and FTBR for this amazing kit. :beer:
