944 alingement specifications

Tried search already -What are some good numbers for front and rear alingement specifications for a 944 N/A? Looking for a performance set up, suitable for DE events.

Jim Pasha wrote an article for Excellence about 944 suspension tuning. It gives a good overview of suspension options/applications and includes alignment specs for the different set-ups. It can be found at: www.924.org/techsection/SuspensionPreparation.htm

"Looking for a performance set up, suitable for DE events"

Well, there's no one alignment setting that's going to be optimal for both street use and DE events. If you have a set-up that's good for overall longevity and response on the street, it'll be completely unworthy for performance. Conversely, an alignment that'll give you maximum performance at DE events will result in completely unacceptable tyre-wear and lack of stability on the street.

Pasha's site and the manual gives good alignment specs for a street car and will result in long tyre wear and good straight-line stability. To get maximum performance at DE events and be 5% faster than the street alignment you gotta look at the following:

FRONT
camber = -4.5 to -5.5 degrees (depending upon spring-rates, swaybars and tyre model)
caster = 3.5 degrees (+1 more than stock, as advised by Porsche TSB for 18" wheels)
toe = 1/32nd to 1/16th toe-in for tight courses, zero toe for fast courses

REAR
camber = -3.5 to -4.5 (about 1 less than front to account for difference in camber-curves)
toe = 1/32nd to 1/16th toe-out for tight courses, zero toe for fast courses

This will work well for a 944 with soft street suspension and stock springs and swaybars. With stiffer springs and sway-bars, you can reduce the camber by about 1 degree. The tyre model you use also determines the alignment.

With soft supple race-rubber like Hoosier slicks, you want about 1 degree more negative camber than stiffer DOT R-compound tyres.

Thanks for the help. I have one 944 that is transitioning to a full track car and another that is in the rebuild/reconditioning phase - I am caught in the middle right now and need to work the middle -can't go to extreme yet.
