A definite upgrade from the stock wheel trim is the carbon fiber wheel trim with accents. You can add to your Sport Line, M Sport or Luxury line.
Or, just keep it classy for the M2, M3, and M4 guys.
High Gloss 2x2 Carbon Fiber Weave.
The trim just swaps with your existing one. You get the whole outer carbon piece with the inner accent.
Installtion requires no professional help. Just take your wheel off, and you're good.
Fitment is perfect and just like OEM.
