D2 Super Racing coilover kit for BMW M3 E30 51mm strut combo springs

Specifications of the D2 Coilovers Super Racing

The new Super Racing range from D2 is specifically intended for competition. These new suspensions have been designed to be adjustable in rebound and compression separately. The internal pressure of the gas (Nitrogen) can also be controlled and adjusted, allowing extremely precise adjustments to be made (more than 1000 different positions per shock absorber). The tanks are separate and ensure a maximum oil and gas capacity, in order to limit the rise in temperature of the shock absorbers for optimum endurance and foolproof. The reservoirs are separate attached to the shock body directly.

There are an infinite number of adjustments on these coilovers so they allow tuning of the chassis suspension that will delight the most demanding teams. Also, camber and caster are adjustable at the front via the shock absorber cup (McPherson type struts only). The kit will be entirely designed and custom-made at the D2 Racing factory, depending on your use (circuit, rally, drift, etc.) and according to your requirements, taking into account the specifics of your vehicle.

The diagram in photo 2 shows you the difference between the separate springs (identical configuration to the origin), and the combined springs (spring around the shock absorber) for E36 and E30. On the E30 version, the strut must be welded at the front: it is a complex job that must be carried out knowingly and with responsibility. STR Performance can perform this installation for you, contact us for more information.

We also specify that your struts must come to us completely disassembled (please remove all the removable parts: springs, flanges, bearings, etc.).
As an example, here is a photo of the struts from a BMW E30 as they should reach us:
