air bag in right rear coil

Any body running this? Or in both coils? Does it really help traction?

unless you find a differant souce than i did you'll have to buy a pair of them. i ran mine each on a seperate line, i put the valves and a gauge for each side in the rear deck area. make big differance being able to preload as you need to. jester did about the same thing with a 4x4 block of wood, but he isn't very high tech sort of guy ,that's why he moderates the carb board.

I run 2 bags in my race car. I have 15 psi in the passenger one and 5 in the driver side.

Properly fine tuning air bags can make an open differential hook up like a posi.
