Why choose a CarbonXtreme

Daily use marks the same zones first on G80 M3 carbon bucket seats: thigh bolsters during entry/exit, the lumbar edge under side-load, shoulder from belt rub, plus high-touch seat cushion (base pad) and door pull/armrest. CarbonXtreme Bolster Protectors address these hot spots with Merino leather / Alcantara panels, laser-cut and stitched to follow OEM seat geometry for a tidy, integrated read.


  • Coverage: targeted thigh, lumbar, shoulder, seat cushion, door pull/armrest; choose single pieces or bundle kits.

  • Fit & Finish: OEM-tone colors (Black, Silverstone, Fiona Red, Kyalami Orange, etc.), disciplined stitch lines, clean edges.

  • Install: non-destructive attachment engineered for firm hold and clean removal—no drilling, no seat teardown.

  • Use Case: ideal for daily ingress/egress, track days, passengers in denim/rivets, and long-term resale protection.

Build a cockpit that stays fresh and cohesive—the quiet, unmistakable premium in crisp edges, consistent symmetry and OEM-logic alignment every time you get in.
