BC Racing ZX Series — Three-Axis Adjustability for Street and Track
The BC Racing ZX Series takes the three-axis, 3-way damper architecture of the race-spec ZR Series and valves it, out of the box, for drivers who split their time between the street and the track. That means you get race-grade adjustability, independent control over rebound and both compression ranges, without the harshness a full race setup brings to daily driving. Each application is extensively tested per chassis, and True Rear configurations are available on applicable divorced-rear platforms. It is the coilover for someone who wants serious tuning range and a car that is still enjoyable on the road.
Race-Grade Three-Axis Adjustability, Tuned for the Street
The ZX Series carries over the three-axis, 3-way damper design of the race-spec ZR Series, giving you independent control across rebound and both the low-speed and high-speed compression ranges. What sets it apart is the valving: it is set from the factory for drivers who move between street and track, so you get the depth of adjustment a race coilover offers without the constant harshness on the road. You can soften the car for a daily commute and firm it up for a track day using the same hardware. It is a genuine dual-purpose setup rather than a compromise in either direction.
Extensively Tested, with True Rear Options
Every ZX Series application is extensively tested per chassis, so the setup arrives dialed in for your specific car rather than adapted from a generic template. On applicable divorced-rear platforms, the ZX Series is available with True Rear configurations, which replace the factory separate spring and shock with a full rear coilover for unified height and damping control at the back of the car. That combination of chassis-specific testing and platform-appropriate hardware is what lets the ZX Series deliver on both the street and the track.
