Just got home from studying, and woohoo these were in my mailbox. Decided to do a quick video of them for all those people interested in sorbothane bumpers.
thanks for the vid. i was wondering what the difference was. I bought 40d according to a website's advice, but I think it's too soft. it feels way to soft. I don't know in what kind of gearbox setup you would use 40d. i'm trying to build a hs gearbox. i'm going to have to reorder 70d. what thickness did you use? 3/16" or 1/4"?
