BC Racing Coilover Suspension Kit - BMW M3 (E46) (OFF CENTRE)


The BC ER Series Coilover Suspension Kit features 30 levels of separate rebound and compression damping force adjustment, full-length height adjustment allowing extremely low ride height, and external reservoirs. The BC ER Series Coilover has been especially designed and developed to meet the demands of the serious driver for professional competition use. Its external reservoirs allow more oil to be contained than a conventional coilover, to slow down oil temperature increase.

The separate compression adjustment provides a wider range of tuning settings than a traditional coilover, in which only slight changes occur to compression when adjusting the rebound.

The BC ER Series Coilover offers complete adjustment for the individual that demands serious performance and wants to fine tune their suspension setup to their needs
