Öhlins 05173-12 Helper Coil Spring - 61 mm ID - 7.5 N/mm - BMW F87 M2, F80 M3, F82 F83 M4 - R&T DFV

Unlock consistent grip and quiet, precise suspension behaviour with the genuine Öhlins 05173-12 helper coil spring. This tender or keeper spring is the correct 61 mm internal diameter unit used on Öhlins Road and Track DFV kits for the BMW F87 M2 and M2 Competition, F80 M3, and F82 F83 M4. Rated at 7.5 N/mm, it maintains main spring tension through full droop, stabilises the chassis, reduces noises from unseated coils, and keeps the tyre in contact with the tarmac for sharper turn-in and traction on both road and track.

We choose this Öhlins helper spring for our own builds and customer cars at MJ Modifications, and the feedback is consistently positive: better balance, more predictable handling and smoother operation from quality hardware that just works.
