Bilstein B8 35-115946 Offside Front Damper for BMW 1 Series E81 E82 E87 E88

Transform the way your BMW 1 Series drives with the Bilstein B8 front right damper, part number 35-115946. This uprated offside strut is engineered for cars running shorter springs or factory sport chassis, delivering sharper steering response, flatter cornering and rock-solid stability without ruining daily comfort. It is a direct bolt-on for E81, E82, E87 and E88 models and a proven choice for spirited road use and the odd track session.

We fit B8 kits on our own builds and customer cars and the results speak for themselves. Expect tighter body control, increased confidence at speed and a genuinely more connected feel on British roads.
