Keith,
I have several odd sources of bump stops if you can't find any you like.
I have a few more question about these air bags too.
Will they do more to work with the shocks in controlling the suspension?
For example, if you hit a bump (at Maxton?) and the suspension compressed
enough to slam into the snubbers. Will the rebound be the same as with a
conventional coil spring, or will the bag just return to it's original shape
and allow the shock to dampen the bounce? Will you have to change shocks to
work with the bags?
I guess I'd really have to see the car with the air bags installed. It
all sounds like a lot of work, and leaves you with very limited travel.
Maybe it's time to change the whole front suspension, reverse the spindles
or channel the body if you want it closer to the ground.
I got my first issue of Bonneville Racing News today. Very interesting
reading, and well worth the subscription price. I'm hoping the "Thunder
Down Under" video is available soon. While I'm stuck in bed next week after
surgery on my foot (maybe it'll make me faster) I was looking forward to
watching it, over and over...
