My '69 seems to get a lot of wheel hop in the back. I am pushing 550HP. and the traction bars just don't cut it. I have 315x35x17 tires on the back. anyone been experimenting with different leaf springs? or coilovers for more down force on the differential? I know a 3 link system is the best, but I would lose the back seat. I have an 8 point rollbar now with subframe con.
Andy, try Landrum Spring Service in Atlanta, Ga. 404-622-9348. Also try Racesearch.com. I'm also guessing you don't have a rear sway bar, try @ 5/8 to 3/4. Using a 3/4 Quickor bar stopped my problem by itself.
