On my 550, I had 19's and went up to 20's. The ride got better and I was so much happier. I will stay with 20's on this one as I will use my old wheels and put these stock ones up in the attic. Personalization is what its about and for the ones I have seen on here with 21's I think it will be great. Hey avi8tor and mcvaughan we should get together and take a drive up the national forrest or out in katy back roads together. Matt, I still want to hear that akrapovic. Also, don't forget, first sat in january is cars and coffee 249/louetta. Lets represent the m5 up there. Dingding should be there also along with the other houston m5 crew.
