Hi, well at long last my project car is almost complete. It came off the road in 2006 for a lot of reason. The car is now complete again and has a nice 3.2 in it along with a host of other upgrades.
I have just fitted Michelin pilot sport 3 front and rear.
I want to send it for an alignment, but the spec for the rear toe in settings are in degree.
Can anyone tell me what the setting is in millimeters?
Thanks
Geoff

I assume you mean Toe IN ;-)

As for the measurement it is:
Wheel Diameter (mm)= WD
Angle of Toe (degrees) = AT
Distance of Toe = DT (mm)

DT = WD * SIN(AT)

So for a 15 inch rim (15 inches = 381mm)
And One degree of Toe:

DT = 381(mm) * SIN(1.0) = 381 * 0.01745 = 6.65 mm

So for every degree of Toe-IN (near zero) you would space the forward rim of the wheel IN by ~6.6mm (or ~ 1/4 inch)

You can read, right?
Might want to do that first.
