So I have been after some ideas for jack pads/posts on the challenge car, the side pipes give us another challenge, just jacking under teh 4" tube does not give us much room, as when at the track there are uneven surfaces and oten the jack does not roll and thus the chance of the jack slipping off the tube. We do have a simular spot as the GTMin the rear where teh tubes come together and this is where a body mount plate is put on, I don't use the body mount plate so that may a place to start, if anyone elese has looked at this, I'm open to ideas
