I've recently picked up my new GP2 and was impressed with the rear diffuser fitted to the
JCW rear body kit.
I've recently fitted one to my wifes roadster and can confirm it all simply bolts on and no cutting required, fitted in under an hour.
I seem to remember a thread here on the GP2 Diffuser but could not find it so sorry for posting it, but thought I would share the ease of fitting and the confirmation they fit the
JCW bumper with no problems.
I believe these may be available from BMW Mini garages but can also be found on ebay
Item no 321070455450, I think they ship world wide?
If anyone would like pictures please let me know, I've taken some every step of the way.
