What is the stock size? dia x width?
How much does it weigh?

What about the 19"?

I might put a set on the M Coupe and need to know what to look for.

Thanks.

Stock 18s are 8" width front and 9" rear. Offsets are 47mm front, 26mm rear (rear will not fit your Coupe without spacers).

Weights are around 26 front and 28 rear.

I hear the 19s weigh about the same.

18x8 (f) 18x9 (r) w/ 225/45/18 (f) and 255/40/18 (r)

From BMW USA site:

"Exterior


M-style cast-alloy wheels with Satin Chrome finish and safe-stop rim design, 18 x 8.0 front, 18 x 9.0 rear, with asymmetric hump


225/45ZR-18 front and 255/40ZR-18 rear performance tires


M Double Spoke forged and polished alloy wheels, 19 x 8 front, 19 x 9.5 rear; 225/40ZR - 19 front performance tires, 255/35ZR - 19 rear performance tires"

Your tires sizes are right, but the wheels are definately 8.0" front and 9.0" rear.

I wish you were right becasue it would be easier to find wheels for A Stock autocross use.

since the oem 19's are forged they weigh pretty much the same as the cast 18's.

You're right... I wasn't thinking straight, I got my wheel sizes confused with my upgrade options... Wasn't thinking right at the time...
