I know a while back there was a thread about the 1M fender liners rubbing in the front at full lock and BMW issuing replacements if people complained but I don't know if it has been pointed out that BMW actually revised the front fender liners to give more clearance.
When the 1M first came out I purchased the 1M fender liners for my ER front end and last when building my 1M front end I noticed that the new liners are different. BMW has moulded them to allow more clearance.
Old 1M liner - note the groove was from some rubbing. Originally it was much flatter
New 1M fender liner - Note the larger groove
