BBS LM 5x114.3 18x8.5+38 Diamond Black Wheels for the 2026 Honda Civic Si

The 18x8.5" LM at +38 offset sits 12mm further outboard than the factory 18x8.0 +50 wheel, positioning it near the aggressive end of the tested +35 to +45 range for this platform. On most Civic Si trims, this setup typically requires fender rolling and may demand minor suspension adjustment or coilover tuning to clear; lowering amplifies clearance concerns. Pairing with the factory 235/40R18 tire maintains sidewall height and keeps load-carrying capacity aligned with OEM specs.
