The BMW 3 Series can be adjusted to the needs of the driver, making the ride variable from comfortable to sporty stiff. Adjustments can be made with the kit installed using a spindle on the end of the piston rod. Dampening can be adjusted without removing the wheels. At the front, adjustments are made on top of the strut, in the rear removal of the trunk liner is required to access the top of the rear struts. Adjustments to the ride height requires removing the wheels for your BMW 3 Series.
