If you own a G80 M3, G82 M4 or G87 M2 with M Carbon bucket seats, you've probably already seen it. The seatbelt runs over the upper bolster and rubs the same spot every time you buckle up. Over time the leather goes shiny and the Alcantara starts to pill, right where you see it every time you open the door.
This BMW M Carbon bucket seat belt protector set from Wunderworks stops it before it starts. It puts a layer of matching leather and Alcantara between the belt and your seat, so the belt wears the protector, not the upholstery.
How the M Carbon Bucket Seat Belt Protector Works
Each protector wraps the upper seat area where the belt makes contact. An integrated snap-button strap holds the factory seatbelt webbing in its correct position, so it stops sliding and rubbing across the bolster every time you get in, get out, or lean into a corner. The belt still works exactly as BMW designed it. It just stops grinding into your seat.
Matched to Your Factory Interior
These don't look like an add-on. Each set uses real leather and Alcantara with factory-matched stitching, in seven color combinations designed to match BMW M interior upholstery. Pick the color that matches your seats and they blend right in. Designed and made in Poland.
No Cutting, Fully Reversible
The protectors attach with integrated Velcro fastening. Nothing gets cut, drilled or glued, and your seats stay exactly as they left the factory. Take them off before a sale or a detail and there's no trace they were ever there.

- Position the protector over the upper seat area where the seatbelt makes contact.
- Secure it with the integrated Velcro fastening so it sits snug and flat against the seat.
- Route the factory seatbelt webbing through the snap-button strap and close the snap.
- Buckle and unbuckle a few times to confirm the belt moves freely and retracts normally.
- Repeat on the other seat.
