Guys,

just curious ......what is a typical 964/C2 track camber setting ? 17" wheels,monoballs and track tires MPSC

Thanks

If like the ealier cars everyone goes for max (matching) settings. Can you have to much negative camber F or R with track tyres and stock suspension pickups :?

Front, -2.2 camber, 0 toe, as much caster as you can get
Rear -1.8 camber, 15 minutes of toe each side

Due to the 964 front end geometry, the 964 will naturally toe out under braking as the front end compresses. Don't lower the car more than RS spec because of this...

thanks for the info .......Basically reverse of early cars......so Bilstein RS pieces and 400frt/600rr Springs?

That doesn't matter so much; the height of the car really matters because of bumpsteer...

He said that he had monoballs; so I thought they were attached to plates.

DR, the most I could get upfront before upgrading to plates was 2.0 degrees negative camber.

Camber setting relates to the tires you're using as well. When I ran Michelin Cups, the car was set up with the help of the Michelin engineers and we determined that we needed almost 3 degrees of negative camber to achieve the proper heat temps.

Believe it or not, if you run Michelin Cups at a club race and the Michelin truck/engineers are at the track, they provide free pit support. Nothing nicer than pulling in and having two uniformed Michelin tire engineers taking tire temps and air pressures.

Right now I am running -3.0/-3.0 camber and my temps in Nov were still a bit higher on the outside front and rear. I am changing my springs from 900/750 to 800/800 and will need another align/corner and will probably keep the camber there as it is maxxed out in the front. Toe is 0 up front and I think 1.5 rear. Not sure about caster.

Car is driven to the track, but that is about it. Not much wear on the insides.

Here is a presentation by Michelin on MPSC I found on the web.

http://www.cb-racing.com/PilotCup_Presentation.PPT

It has set up recommendation by model near the end.

-2.5 rear camber
-1.5 front camber... I hate to disagree, but I can't see any reason to ever run more front camber in a 911...

6mm in in the rear 4mm out in the front... worked for spot, best compromise 964/965 alignment I know of... Drive it and see if you need more camber based on how much your tires are rolling, tire pressures, and tire temps... if your tire temps are in the sweet spot, you can add camber to help wear and give you more traction, and helpm spread the sweet temps across the tire.
