Road race alignment specs

2001 M3 - 245/45/17 Toyo 888

I recently upgraded to K-Sport coil over / CC and had the car aligned to be 80/20 (track/street). The car handled great but I ate through a set of Toyo 888 tires. Does this alignment look right? Any suggestions on a better balance between grip and Tire longevity?

Front:
Camber Left -3.23 right -2.93
Cross Camber -.29
Toe Left .026 Right -.3
Total toe -.06

Rear:
Camber Left -2.17 right -2.33
Cross Camber .16
Toe Left .10 Right .08
Total toe .16
Thrust angle .02

Is this a track car or a street car? How did the tires wear?

Looks like your at the max camber difference in the front. I would adjust camber depending on how the shoulder is wearing on track. So you have toe in(+) left and toe out(-) on the right? Toe should be closer to 0 deg. unless your looking for better "turn in".

Rear cross camber should be closer than the front. The toe in the rear should also be closer to 0. Its a compromise between getting the car to rotate in turns and straight away stability.

I think adjusting accordingly will help tire wear and even improve handling. Driving habits are often overlooked as well.

Car is 80% track, 20% street

The front tires were down to the cord on the inside half of the tires and were cupping on the outside. The rears were even wear.

One of the instructors who was behind me told me that I was driving like a straight axel car but he didn't elaborate? (I formally raced a Mustang) Any feedback on the driving habits mentioned? This is my first season with an M3/independent suspension.

Put the toe to zero.
Tire pressure should be checked and adjusted probably.
If the car is under steering slow down u are over driving the tires.
Use a temp gauge to shoot the inside and outside of tires. Adjust camber to get even temp across the tire.
