E90 E91 E92 E93 Bilstein B12 Pro Kit (46-180568) - fast road, track day, daily driver

Bilstein’s B12 Pro Kit (46-180568) is a matched shock-and-spring set engineered for the E90, E91, E92 and E93 3 Series - specifically the N54, N55 and M57-powered models: 335i, 335d, 330d, 325d. Not for N20/N26 or LCI facelifts with revised rear subframes.

It’s a fast road suspension package - not coilovers, not OEM replacement, not a show-car gimmick. Think sharper turn-in, less squat under acceleration, reduced roll mid-corner, and composure at speed - all without sacrificing daily drivability.

• Stage 1-ready: pairs cleanly with standard brakes, stock wheels and modest power increases
• Track day capable: progressive damping control holds line under load; no fade on extended laps
• Decat or cat-back friendly: no clearance issues with common exhaust upgrades
• Fast road spec: ~35-40 mm front / ~30-35 mm rear drop - enough to tuck the arches, not enough to scrape speed bumps
