So, I'm getting two new front tyres fitted tomorrow and I'm getting a 4 wheel alignment check/adjust next week, but what geometry should I get the car set up to?

The spec is:
1999 MPi with Sportspack alloys.
Adjustable negative camber bottom arms.
H/D tie rods - poly bushes throughout.
Standard Sportspack Konis.
Adjusta rides (not to lower the car but to level out the corners - it may be a little lower but not by much. The rear isn't quite so high as standard over the front).
Tyres are standard 28psi front, 26psi rear.

I had the car set up a few years ago but can't find the sheet. It had more negative camber at the front - the rear, although not adjustable, were pretty much dead ahead. Like this the car drove pretty well actually - good turn in, good grip, not too much tramlining and the like.
Any views/opinions welcome.
Cheers,
Graham

If I were doing this I would go for 1 deg to 1.5 deg neg on the front with 2.75 deg to 3 deg castor and tracked straight ahead i.e. no toe-in or toe-out.
On the back I would go for 0 to 0.5 deg neg with 1mm to 2mm toe-in.

Cheers Peter,
I seem to remember getting the car set up with 1 degree neg camber last time. Hopefully it'll drive as well after its done too! (And I won't get hit by an uninsured driver again and knock it all out frown )
