Noooooooooo!!! Ya don't want toe OUT. Not unless you ever want to drive
the car over 50 mph in a straight line. What E36 M3's want...nay, what
they CRAVE (other than a breathless Lisa the 02 Princess sitting in the
seat after a sweaty bike ride) is great big gobs of NEGATIVE Camber and an
itty bit of Toe IN.
Aftermarket Sway bars will make a very large difference BTW. Its quite
noticeable. Don't dismiss them as your suspension mods are not complete
until you do the sways (rear is a PITA to install - front is one beer easy).
Best mix of settings for the track:
1/16" toe IN on the front. (and the Dinan "street" - 5/8 degree Camber
Plates unless you want to replace your street tires every 6,000 miles by
using the more aggressive track plates. This will give you about -2
degrees total neg camber on the front with a lowered car.)
1/8" toe IN on the rear.
- -2 Degrees negative camber on the rear - that's about the max you can dial in.
When you go to put your car on the rack, have a full tank of gas in it and
sit yourself in the drivers seat when they do the adjustment. MAKE SURE
THE TECH SETTLES THE CAR ON THE RACK.
The toe IN on the rear keeps the car stable. With Zero toes settings all
around, the car corners like a banshee but becomes seriously nervous at
over 80 mph and will jump left/right when you stomp the brakes at speed.
This would be a great set-up for an all-autocross car, but will scare the
whee outta you at the track. When the car is at speed, the aerodynamic and
friction forces will realistically convert that 1/16" toe in to an
effective rate of ZERO toe for the front (Thanks Pete Read for this tip!).
If you start with zero settings you will be at toe out when the car is moving.
How to I know all this?? Three trips to the alignment rack in the fall and
lots of conversations with Will Turner and TC Kline.
Come to Summit in March or PizzaFest in April and you can take a spin in
the Rabidmobile and see how you like the set-up I have.

P.S. I'm insanely jealous that Bob Stommel has bought a LTW M3! Now I
haveta upgrade again (*sigh*).
