M Roadster wheels

[sikbrik]

Has anyone tried M Roadster (or M Coupe) wheels on their ti?

It looks like the offset is different than the regular staggered M3 wheels.
Front
Wheels: 7.5Jx17 (41mm offset)
Tires: 225/45/17
Rear
Wheels: 9Jx17 (8mm offset)
Tires: 245/40/17

I found those specs on a Z3 site. Can anybody vouch for the validity? I wish it told backspacing because with a 9" wide wheel, knowing the offset doesn't really help me by itself.

The tire sizes sound okay from what I've read in this forum since that's what the factory M3 staggered wheels are running and a few of you have them on with no problems.

I'm just curious if they're offset to the "wrong" side...I mean, can I just run a spacer on them or do they already stick out too far without a spacer...do I need to move them inboard, in other words?

I bought a set of 16" wheels last week but somebody is willing to trade me their 17" M Roadster wheels for them...if it seems crazy, I'll just pop the 16" wheels on and be done with it. I think the 17" M/Z3 wheels look pretty sweet, though. THANKS!!!
