I just got around to putting these on earlier today and after a short drive I'm thoroughly pleased! the Fortune rear shock that I had was far too short so I was running without the factory bump stops period. Subsequently the ride was brutal when it came to big dips or sharp jolts regardless of speed due to the metal on metal contact and the shock bottoming out. On a side note I'll update the Fortune Auto suspension thread for those interested about the progress with that. In the mean time I've swapped back to the factory shock with the much lowered spring (last time I checked the rear fender was 23" from the ground). In a week or so I'll give an update once I get some more realistic miles on the bump stops. At the moment I'm thinking one or two notches can go, but we'll see. Regardless I'd recommend these as a cheap, easy, fix to anybody with a lowered set up. The hardest part of the install was removing the bottom bolt on the shock so the torsion beam would drop low enough to remove the spring. From there all you have to do it remove the rear perch, which is secured via a 12mm bolt, drill out the hole with a 3/8" bit, and then rebolt the new stops in. I was replacing the rear shocks already so it only made sense to switch these out too. In case anybody was on the fence hopefully this will help out a bit. Included are a couple pictures for reference. First is the new bumpstop, second is the difference between the two, third is the factory perch that gets removed, fourth is the damage said perch did, and finally the car needs MoAr LoW!!1!, haha.
