Going on another recent thread, some C3 racers are talking about how the lowered snubbers will also increase traction by preventing so much rear spring travel (what goes up must come down). If the car doesn't squat way down, then it doesn't rebound way up. It's the "on the way up" part that unweights the rear, allowing the tires to become less planted (is that a word/term?). I'm definitely going to lower my snubbers!!!!

Ok, I have a stupid question to ask here. When you say "snubbers" are you referring to the rubber stops that are tacked on to the bottom side of the frame that keep the trailing arm off of it?

Yes, that's them. I intend to have my budy weld (I can't weld) a piece of box tubing where the existing snubber sits. Then I'll mount the new snubber to the box tubing. A lot of the drag racers on the forum are doing or have done this.

I had a recurring u-joint breakage problem. Finally traced it to a torn bumper (snubber)

Ok, this same idea was brought to my attention by Art, of Art's Corvette in B.G. The question I forgot to ask was how far off of the frame you should space them.

What is the general consensus on that?

Just my personal opinion, but I think it all depends on how hard you are going to be launching, and how much road use you are going to see. I'm going to lower mine 2 inches. That way while on the highway, I shouldn't have to worry about bottoming out. If you are going to see mostlt track time, then you could probably even go lower. To me though, I think that limiting the travel by two inches is a lot and should help reduce the extreme stresses of launching. Only time will tell though. I'm shotting to have it back out at the track in the next month and a half to two months.
