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.

24mm front bar for me. front springs 275lbs. currently no rear bar. wanting to up the front spring rate to 300-325 lbs

Hi Tom,

I'm running dual 20mm bars in the front, single adjustable 20mm in the rear. Front springs are 250# on shortened B310 struts and Ground Control coil over kit. Rear are stock with 2.5" lowering blocks with integrated shock mounts (sedan). 13x8 Bassett wheels with 4" backspace and Toyo R888 225/45-13. With the front end alignment at -2.5° camber and 7.1° caster the tire wear is even in heavy autocross use.

The front springs are 250, not sure what the rears are but I seem to recall it's fairly soft in the 110-120 range.

Hi Benny,
Thats seems a very stiff spring for a light little car. And no rear bar- are you running an open diff or an lsd?
Cheers
