The ZX Series is designed for cars that spend more time on the track or drifting than on the road. It combines a monotube shock absorber, digressive piston, and double piston with a high-viscosity index synthetic oil that barely changes when heated. The external reservoir increases oil capacity, ensuring the feel remains consistent session after session. Its main feature is the 3-way independent adjustment: 30 clicks of rebound, 20 of low-speed compression, and 12 of high-speed compression.
Complete kit for all four wheels of the BMW 3 Series E46 RWD (98-06), excluding M3. It uses an integrated rear configuration: the spring and shock absorber form a single unit instead of being separate as in the factory setup, which allows for rear ride height adjustment directly on the shock absorber. Weighs 24 kg. Manufacturer reference I-31-ZX.
Features in the front and in the rear. The front axle supports camber and caster adjustment, a feature not available in all applications. Ride height is adjusted independently of spring preload, and the conical lower collar prevents the adjustment from shifting with use. Includes dust covers to protect the seals and a 1-year warranty against manufacturing defects.
There are 9 spring rate combinations available. The one BC Racing defines as the default for this car is 6/5 kg/mm.
Before buying
Before installation, the chassis must be reinforced at the rear mounting points. The integrated assembly introduces loads that the original setup distributed differently, and BC Racing makes the validity of the kit conditional on this work being performed. This is a task for a specialized workshop and should be factored into the budget.
