18"track wheels

[_Nathan_]

18x10 ET25 all round for me, I have some camber at the front and at the rear for sure but no idea how much, I have some suspension with springs at the front at back and ride height is 40mm from the floor to the splitter.

Hope that was as helpful as Duncans post :thumbs:

Not wishing to hijack thread ..question is relevant here, and Rob before you fookin start ...I have searched but cant de assed any more ...so ...the question i have to ask that is relevant to this post and not wishing to hijack the lads thread is this .... it isnt my intention to cause offence or upset anyone if I am deemed to have hijacked this thread ...with my question .... but if anyone IS offended ..or upset ...BOLLOCKS ANYWAY :birdman:

wHATS THE FOOKIN ROLLING CIRCUMFERENCE OF OEM CSL WHEELS .....WITH TYRES ON OF COURSE !:hahaha: ... BOUT 640MM ???

642 on the back, 647 on the front :birdman:If I can figure it out why the f can't you:blalalala:

I can ! C = PI X DIAMETER WHERE PI EQUALS 3.1416 GIVE OR TAKE !!!
Just realise that I have a program for calculating RC and offset diffcalled Rubber Fetish !!
:banghead::banghead: .. oh ... and you gave me the fookin Rolling DIAMETER NOT the circumference !:blalalala:

Another Calculator here http://www.brspecialtuning.co.uk/Tyr...calculator.htm

So .... running 24/64-18 slicks will give me a difference of 2mm on the diameter on the rear, sooooo... slightly quicker acceleration Nathan ?
So the front wheels are actually bigger than the rears !

It does, but the rear arches on a standard M3 are not rolled - unlike the CSL.

This is correct,well done Rob,but are there any other differences between the Two shells.

2mm diameter is ~6.5mm on the circumference...fractionally quicker then..


you bought them cheap as chips tyres then yet?

It will indeed slightly reduce the effective gearing, not by enough to notice though, basically the difference in tread depth between the start and end of a track day

Suspension mounting positions?
