Rear sway bar options
 

OK guys.

I've been running with the M coupe rear sway for a while now, and I really like it. I miced it before installation, as compared to an M roadster rear sway and found it to be slightly larger, and it also has a different part number. All I had to do was change the body bushings and clamps to run this sway on the stock mounting points; no cutting, no welding.

Now to the point: I found the two part numbers as well as the diameter specifications for these two sway bars. Retail is $128.34 each.

M Roadster (US and Europe): 18.5mm 33552228367
M coupe (US and Europe):19mm 33552228367
