Eibach Pro-Street S Kit for BMW E46 M3
BMWâ€™s E46 M3 is now firmly in the â€˜bargain basementâ€™ category, with even the tidiest examples being available for around five or six thousand pounds. As an affordable RWD driving platform, itâ€™s the perfect basis for tuning, so the announcement of Eibachâ€™s adjustable Pro-Street S coilover kit will come as welcome news to many disciples of the Blue Propeller.
Fabricated entirely by Eibachâ€™s in-house German motorsport division, this kit offers competition quality, with road car manners â€“ and is suitable for the Coupe, Saloon, and Convertible models.
Careful choice of spring and damper rate means that easy set-up and adjustment has been designed into the units from the outset and the adjustable spring seat can be easily wound up or down in order to achieve the perfect stance – or corner weighting, before being easily locked off with a stainless allen bolt. Eibach actually uses the hugely-respected, multi-championship winning ERS range of race springs on the Pro-Street units, which goes a long way towards explaining their race pedigree. Although not designed as a race-spec unit, there are numerous club-level competitors who have used the previous generation kit to great effect in British motorsport. To that end, the units can also accept any springs from Eibachâ€™s ERS range, allowing rates and free lengths to be adjusted to ownerâ€™s preference, if required.
This latest kit, designed specifically for the car, uses the latest materials and construction techniques to give any of the E46 models a wide range of ride-height adjustment, while still retaining a fantastic ride quality. As the name suggests, Pro-Street S units are designed with road-use in mind, although thanks to their stainless steel construction, precision damper units and unparalleled build quality, they will also be a pretty effective upgrade on track, too.
Ride height can be adjusted from anywhere between -20mm and -40mm from the M3s already lower ride height, offering a truly aggressive stance if required, or a more subtle drop if preferred. Damper rates are computer matched with the springs at the Eibach factory, making the Pro-Street S kit a true â€˜fit and forgetâ€™ proposition once the desired ride-height has been set.
