CAtuned Dynamic Drift Coilover System Compatible with E30
E30: 51MM- 10KG Front/ 8KG Rear
Rear is Shock & Spring integrated in to one unit.
We suggest reinforcing the rear strut towers with a good X brace to support the strut towers from ripping.
Some modifications are required in the rear. We can guide you with this.

The monotube inverted design is utilized to reduce the effect on the damping oil and shock piston resulting from high temperature from the brake system, engine and much more. Also to take side loading better without major deflection. The damper rod is made up-side down to save unsprung weight for better suspension response. The inverted strut is built stronger than a regular shock due to different shock body construction with an added outer sleeve. For the suspension system with rear A-Arm strut model, the rear damper rod has been thickened to 20mm, which enables to support a bit more side G Force, and makes a vehicle more stable. In addition, the thickened damper rod can prevent from being bent or deformed. See pictures of the difference between the Dynamic Drift and the Performance coilovers.
The spring is made from high quality SAE9254 steel for optimal durability and high tensile strength. The spring rate remains unchanged and undeformed even after the spring has been subjected to long term wear and even if compressed or extended. The spring seats are made from forged aluminum for durability and rigidity. At the front the wave alloy steel thrust washer is installed between a lower locking collar and a bottom mount. The wave thrust washer can provide a controlled amount of friction between the lower locking collar and the bottom mount to effectively prevent the lower bracket from spinning around or becoming loose. PENDING Patent
Spring bearing is mounted between the spring and the top cap to make the handling more agile and to eliminate the spring noise caused by car cornering. This design enables the spring and the shock to perform together more effectively. Clean and grease the spring bearing periodically to prevent from rust or corrosion, which can make the spring bearing last longer.
Note: 55mm steel shock body is coated with zinc plating for corrosion resistant in the harsh conditions of motor sport and road grime. The rest of the pieces are anodized and powder-coated where possible.
