I have only used the shock o-ring caps and they're awesome. the threads are super clean and they actually have a tighter fit around the lower bushing. The anodizing is good quality and you can use a wrench to tighten them if you want.
Thanks, I'll probably order a few things here and there because those dang things are expensive........
Ok forgive the question, I keep hearing people talk about testing out your slipper by running it on the straightaway of your track. I've always done it by holding the wheels and see how far the front lifts up. So on the track what exactly are you looking for the car to do, and how do you do this? Thanks
