The race suspension prep manual on the site has a 1" front bar and a 7/8" rear bar (25mm / 23mm) I'm running 7/8 front and 5/8 rear from Addco per the competition catalog. So I'm curious what most people use in their track cars. Keep in mind the tires run on the original Devendorf coupe would likely have offered less grip then what we run, I'm considering trying this set up as it's more of a softer springs bigger bar set-up which I've found worked well on other cars.
