The G80 BMW M3 is offered in two drivetrain configurations: rear-wheel drive (RWD) and all-wheel drive (xDrive). Both are extraordinary cars, but they attract different owners with different upgrade priorities. Here's how carbon fiber fits into the upgrade strategy for each.
G80 M3 RWD: The Purist's Choice
The RWD G80 M3 weighs approximately 50 lbs less than the xDrive variant. For track-focused RWD M3 owners, that weight advantage is part of the car's appeal — and carbon fiber upgrades extend that philosophy. A carbon fiber hood, trunk lid, and splitter package on a RWD G80 M3 can save an additional 30–40 lbs, reinforcing the car's focus on driver involvement over outright all-weather performance.
Carbon fiber aerodynamic parts also matter more on the RWD variant at the limit — with power going to only two wheels, maintaining front and rear aerodynamic balance is more critical for safe, consistent lap times.
G80 M3 xDrive: The All-Weather Performer
The xDrive M3 weighs more but makes better use of its power in cold or wet conditions. For xDrive owners, carbon fiber upgrades are primarily about aesthetics and modest performance gains — weight reduction is less of an obsession when the car weighs 3,900+ lbs in full trim.
That said, the xDrive M3's exterior is identical to the RWD variant, so all the same carbon fiber parts — grilles, mirror covers, diffusers, and splitters — fit and look equally good on both.
Verdict
Both benefit enormously. RWD M3 owners get proportionally larger performance gains from weight reduction. xDrive M3 owners get the same visual transformation. Shop all G80 M3 carbon fiber →
