[BMWZ4RIDER]

Some Ideas:
Carbon Fiber Black and White Roundels or Layover covering the Blue with black CF wrap OR all new Roundels (expensive.) The wrap works well BUT may not last in the FL heat. ??
Painted Calipers or as stated above if the budget allows- Brembo brake sets
Rear Carbon Fiber Diffuser
CF Door Sill Overlay
Aluminum Pedal Set
Black out and/or body color paint of the Front Lower L and R side grills and inserts and gloss black middle grill
Black BMW Performance Kidney Grills Set (or paint your own Gloss or Matt Black, as I did.)
Body Color Painted Roll Bars
Black out film for the Front and rear reflectors
