The DS Series brings BC's proprietary digressive piston to your BMW 3 SERIES E46 (M3). It adds damping force where you feel it most — at low shaft speeds (0–50mm/s) — to keep body roll, pitch and dive tightly controlled through technical corners, then stays linear as speeds rise so the ride never turns harsh. The result is a BMW 3 SERIES E46 (M3) that feels planted on a road course without punishing you on the drive there.
Free express shipping Australia-wide on complete coilover kits, dispatched next business day from Kirrawee, NSW. Change-of-mind returns are accepted within 30 days on unfitted, as-new kits in original packaging.
Every BC Racing coilover is covered by a genuine 12-month warranty and is fully rebuildable and serviceable for life. Spare parts are stocked locally, so there's no overseas wait to keep your kit performing.

Yes — this kit fits all BMW 3 SERIES E46 (M3) body styles.
If you have a non-standard chassis or factory suspension upgrade, contact us before ordering and we’ll confirm fitment.
Yes. All BC Racing coilovers use full-thread body construction for continuous height adjustment without affecting damper travel.
We recommend a wheel alignment after any significant ride-height change.
Damping is adjusted via the top-mounted dial — turn clockwise for firmer, counter-clockwise for softer. Always start with all four corners at the same setting and adjust in equal increments.
