Road/Track wheel alignment set up
 

I have fitted a set of Koni sports to my 911SC and am wondering if anyone has a good wheel alignment spec set up for both front and rear (toe,caster and camber) that is a good compromise between road and track. I only do about 4000km a year. The factory set up seems a little conservative to me and am keen to have a drive afer fitting the new shocks. Hope someone can help.

Well, there is no one correct alignment for everyone and every car, but I think you could dial in a little more negative camber front and rear and bring the toe closer to zero for a little more spirited handling.

FWIW, I am running about 1.5 degrees negative camber in the front, 1.3 negative in the rear and as close to zero toe front and rear as I could get it and it suits my driving style just fine. Caster isn't super critical as long as both sided are the same.

hi todd

i think the accepted amount of negative camber (as a starting point) is 1-1.5 in the front and 1.5-2 in the rear (1/2 more in the rear than the front). i am aiming for 1.5/2 (at the moment i have 4 in the rear which is doin my tyres no good at all!).

i have pretty much zero toe in the front and like it. i will aim for zero in the rear too.

good luck.

frt

1/16-1/32" toe in
max caster (but equal)
Camber -1 -- -1.5 deg

Rr

1/32 toe in
Camber -1.5 -- -2 deg

Most people recommend the camber on the front being about 1/2 degree more negative than the front, but some recommend equal camber settings frt to rear, so I suppose that would depend on your driving style. More neg camber in the rear than the front would make the car more prone to understeer than oversteer. Keep in mind that the weight distribution and the gas and brake pedal have a big effect on the attitude of the car, possibly a better way to try to balance under/over steer would be to get an adjustable swaybar for one end of the car (probably the rear)
