Does anyone know if a 2006 Coupe will take the rubber from an M coupe??
Not wheels, just rubber,
Both have 225 front and 255 rear (both 18's), but the M has a 40 profile rear and 45 front while the 3.0si has a 35 rear and 40 front.
The SI has sport suspension btw...
I know it's not a hug difference, but it's almost an inch.

It'll fit, it'll work, your speedo reading will be way off, the car's going to ride about 1/2" too high. It works if you're using same tires on the same axle for a little while, but I wouldn't use it as a permanent solution, and you may rub on full suspension compression.

Works on my 05 Z4 3.0 Sport. Bought set of wheels (18") and tires (stock size) off a new 07 Z4m Coupe. Fills wheel opening but no rubbing - no issues. Small difference in MPH on spedo.

Jackb1 are you running the wheels as is or do you have spacers? Thanks

I found the wheels and tires for sale on one of the forums. New owner of 07 Z4M Coupe had set of CSLs with tires waiting when his new car arrived.
They are exactly OEM as taken off his car and I mounted to my car without spacers. My 05 Z4 is my business lease car. At 8,000 miles I put on this set and just before turn in I will put the originals back on. I just hated the idea of paying for a new set of runflats at turn in and somone else use the new rubber. I will be left with a set of Z4M wheels that I can sell or keep for my 06 Z4M Roadster.
These wheels being off an 07 have the tire pressure modual in the wheel itself. It is not a factor as my 05 still uses the ABS method of measuring difference in revolutions.
My 05 is a completely stock 3.0 with sport. Use you own judgement weather they will fit your Z4. I have pics showing outside fit if you want me to post them.
Hope this helps!
Best!
