negative camber

[911teo]

What are the numbers for the stock set up?

How much negative camber can u dial in?

My car after 2 days at the track has worn all the outside tires both front and rear...

I dont remember the OEM camber figures off the top of my head, however these cars will want a little negative camber. Which will wear the inside of the tire.


I would check the Toe as well to make sure thats not whats eating your tires.

what tire pressures are you running?

I was running 30ps all around cold which became 36 hot.

The car had good grip. It was a tough track for the tires... still I was wondering if I needed to dial in more neg camber.

Will check the toe as well.

Barondw had a post a while back about track setup. About a degree more of neg camber all around. He was kind enough to send me his settings. PM him if you need to dial in your car for the track. AC

Be careful with pressures getting to 36 PSI as the center tread will wear prematurely.

Look to start cold at 29 rear 28 front and make minor adjustments based on how far the shoulder rolls over. Sometimes applying white shoe polish helps see how far the car leans on the sidewall. Scuffing should stay on tread edge and not sidewall.

Also constantly check the all treads and especially the center tread for evidence of chunking...meaning the tread itself starts coming loose from the carcass. Condition usually appears after tracking the car sooner or later. In worse case scenario tread is thrown off the tire. 2nd worse case the tread can be lifted from the carcass when you inspect the tire after each run session.

One last cautionary note check the torque on the wheels after each session, bolts not properly torqued may indicate serious problems with wheels and/or brakes. Wheels should always be hand torqued - no impact wrench for setting final torque levels.
