BC Racing DS Series Coilover Suspension Kit - E30 M3 (51mm Front Struts)

Product Details

Looking for a coilover kit that will provide reliability on street driven vehicles but also deliver the same type of predictable control and increased feedback you would expect from a track car? BC Racing's DS Series Coilovers may be just the ones for you.
 
The DS Series Coilovers use a proprietary digressive piston design that offers the driver increased damping force at low-speed piston velocities while maintaining a linear damper feel at higher piston velocities.  One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g., roll, pitch, dive, and quick weight transitions on technical road courses. You will notice a much more planted and confident chassis feel, with increased feedback through the steering wheel.

The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.

Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.
The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability. 

All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.
