e82 1m look bumper exist on ebay - you cant use official BMW parts though because of the fenders
The recommendation is BMW Performance bumper ( looks like the tii concept 135i bumper) or BMW Msport (135i) bumper
Since you are in the Highlands with those nice roads. Lets just focus on suspension over any looks
- Sub frame bushings
- Springs & Shocks kit - ( eibach/ H&R / Bilstien B12) are all options
- better brake pads or 130i spec caliper & 330i 330mm rotor or e89 z4 330mm front rotor
- M3 arms from TRW
