I put forged Momo wheels on it. They are a perfect fit. I wanted something in addition to the stock M wheels which I think are killer as well. I think its very important not to disturb the clean lines of the M5 with anything to bling. I also have installed HR coilovers on it. Next mod is either bluetooth or Britalman exhaust. Here in Los Angeles we will soon have a no hands on cell calls in ur car. Which I think is great.
