Alignment specifications

Post by mmakay » Mon Jul 16, 2007 1:35 pm

Does anyone have preferred alignment specifications (camber / toe-in) for performance driving ... track days and such?

Dario (I think) had some info on Z4um about it, hopefully he will answer here or PM him. There was a how-to about changing the camber etc yourself, quite interesting.

ok i guess i will start it off

*opens z4 history folder*

Original:
Camber (front): 0
Camber (rear): -1.5
didnt get toe

Note: Mods are with H&R front n rear sways and PSS9 coilovers
First Mod:

Front
L ____ R
Camber -1.30 ___ -1.22
Castor +3.48 ___ +3.56
Toe In 0.5 ______ 0.5
Compression 4 _____ 4

Rear
Camber -1.15 -1.15
Toe In 1.5 1.5
Compression 5 5

Result: This adjustment felt very firm and was well balanced. But when i raised the height of the car from 9cm to 11cm, this adjustment didnt feel as great as the car didnt seem to want to grip as much.

Second Mod:

Front
L R
Camber -1.30 -1.26
Castor +3.48 +3.56
Toe In 0.7 0.7
Compression 6 6

Rear
Camber -3.42 -3.40
Toe In 2.0 2.0
Compression 8 8

Result: This setup felt great especially in the wet compared to the first setup. Running on Pirelli P-Zero Nero's, i was able to obtain the flat spot with 34 psi tyre pressure all round with a reasonable ride comfort. For track, i dialed the coilover compression to 1 for front and 2 for rear.

3rd mod:
Front
L R
Camber -1.5 -1.49
Castor UNK UNK
Toe In 0.7 0.7
Compression 6 6

Rear
Camber -3.41 -3.40
Toe In 1.8 1.8
Compression 8 8

Result: This is the last adjustment i have on the z4. Unfortunately the notes i wrote up for this adjustment went through the wash and i dont have all the precise readings for this. What i found from this adjustment was it was quicker for laptimes but a lot more tiring as i was concentrating a lot harder on keeping the car steady. Tyre pressures used were 38 front HOT and 40 rear HOT

Hope this helps

Note to Mickey: Sephanite drives a RHD vehicle. Don't know if it matters but did want to point that out... :)

RHD shouldn't matter. The fact that it's lowered may, though.

Does anybody know the stock settings for the ///M version?
