useful.. note however that for the m5/m6 reps. the front will not be the same fit as OEM but rather will be tucked in 4mm more.

Thanks for pointing out that slight mistake. I've updated the original post.

Hey jackal nice list you got there. You forgot the M6 reps in 19x8.5 and 19x9.5 set up.

Don't forget about these also.... all colors available and perfect fitment!!

CSL Reps
Front: 8.5 x 18 ET40
Rear: 9.5 x 18 ET45

Rear Tire Size: 255/35-18

Notes: Front will have 12mm LESS clearance on the strut side, and the outside edge of the wheel will extend to THE SAME point as the stock wheel. Rear will have 21mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 5mm.

So, am I to take from the above that you can run the OEM tires with the CSL staggered reps, even though the CSL rears are an ince wider in the rear? Thanks for the post.

If you go to 'specs' for the OEM tires on tirerack you will see that the fronts have a rim width range from 7.5-9" and the rears have a rim width range from 8.5-10" so OEM tires will fit those rims according to Tire Rack.

And for the other posts that said I 'missed' some wheels, I only ran the calculations for rims I was interested in. I din't think its appropriate to push a certain wheel in this thread. There is an entire other forum section for that. This is about fitment vs oem. Thanks.
