DESCRIPTION
The MeisterR ZetaRace Coilovers for the Mazda MX5 Miata (NC) 06-15 are designed for high performance track usage with high-grip compound tires. ZetaRace 11k/7k spring rates for FUN in the Curves, Track, and Autocross.
The core of this performance is the MeisterR SRV (Speed Reactive Valve), which is developed and manufactured in our UK workshop. With over a decade of experience, the SRV is an innovative valve design that combines the quick response of a double digressive valve with the predictable characteristic of a linear valve. This improves steering response, body roll control, and stability while maintaining traction over curbs and rumble strips. The result is a more confident driving experience and faster lap times.

BRIAN'S FEEDBACK. First Impressions! Finally had a local autocross event with these. Finished Top Time of Day. Spring rate equals speed and these have really good rates for a car with a lot of grip like our Supercharged NC. Pavement at venue is breaking up in places and I did start full stiff and find that I needed to back down the damping to 10 clicks off full hard just to keep tires in contact with the pavement, because smooth is fast and tires not on the pavement are not giving us grip. Our Ohlins and ClubSport are smoother, but for the money these are very fast and street ride with reasonable wheel and tire package is not bad at all for the big 11kg/7kg spring rates.
Brian's Track Test. While my autocross impression on rough pavement was positive but perhaps not thrilled, the track day performance really showed these can be fast. Chuckwalla Raceway in our supercharged NC, lap times consistent, and we felt VERY confident in cutting the curbs in this setup. There are lots of choices that cannot cut across the curbs at 80 to 100mph and have you not worry about a spin, this setup absorbs that blow of the curb at speed without upsetting the chassis. They call it their 'SRV', or Speed Reactive Valve, and the track day filled with intentionally cutting over the curbs convinced me it works. For the money, a solid budget track day choice.
