Specifications of DRAG D2 Coilovers
D2 Racing being very present in the automotive world and also in the DRAG environment, they were able to learn and develop a specific range for the discipline of DRAG for the practice of the 400 meters standing start. Note that for this discipline, very special attention has been paid to the phenomenon of compression of the shock absorbers at the start. Indeed, by limiting the compression of the shock absorbers at start-up, traction is markedly improved and the power is transmitted to the ground more quickly, which allows the racing driver to gain a few precious hundredths of a second, while increasing the stability of the vehicle. his vehicle at very high speed. For all coilovers in the DRAG range from D2 Racing , the height regardless of the spring preload, which ensures efficient damping in all circumstances, down to the lowest lowering levels. Camber is also adjustable at the front via the shock absorber cup (valid for McPherson type struts only).
D2 Racing coilovers have a single-tube oil design and offer a lowering range of up to 10 to 12 centimeters depending on the model. The damping (also called "hardness") is adjustable in 36 positions. Its shock absorber body is made of aluminum, which provides them with foolproof anti-corrosion protection. In most cases, these aluminum shock absorbers are less heavy than the original, and therefore also save a few precious kilograms, weight being the sinews of war in the race!

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.
