BMW M4 (G82) Exterior FAQ's

Please read our FAQs page to find out more.

Which exterior mods add measurable function on the M4—not just style?

Front splitters/undertrays stabilize the nose, brake‑ducted bezels reduce fade, and a well‑designed wing improves high‑speed balance and rear grip.

How can I avoid scraping lips once the M4 is lowered?

Test‑fit on ramps, use proper hardware, and consider skid plates or adjustable rods. Spacer options help fine‑tune clearance without losing stance.

Do bumper/grille swaps require sensor recalibration?

If geometry near sensors changes, follow OEM alignment procedures to verify radar/camera sightlines and calibration.
