The MeisterR ZetaCRD coilovers are designed for fast road and occasional track day use. Engineered to reduce body roll while providing compliant handling. Damping and ride height adjustable gives you full control over the vehicle suspension setting for the road or on the track.
ZETA is the symbol for "damping ratio", a measurement describing how oscillations in a system die down after a disturbance. The ability to control oscillations is the most important function of a suspension system and it is the concept that the ZetaCRD coilovers are build upon.
Brian's Feedback: MANY customers asked us to try them. The upside is lots of BIG VALUE here, good quality springs and anodized everything and top mounts. Ride is firm on softest setting to full stiff and cracks in pavement are sharp even on the soft settings when these are fresh from the box, but they break in nicely and get reasonable on ride for the 6kg/5kg spring rates and will charge a canyon or autocross reasonably well. If serious about autocross and track jump to a higher rate kit. No dual flow valve like the much higher cost Ohlins to mask the impact of track curbs and real world potholes but just half the money here too, lots here for the low cost. Not DOT or TUV approved, they come marked 'For Off-Road Use Only'.
Mainly bought this to eliminate some roll that i had with stock ones installed. I had it installed over at Wrench Monkeys in Sacramento and had the height set to 12.75F 13R (might raise it up a bit), dampening 16 from full on front and 19 on rear. Drove down to San Diego with these. I would say these are comfortable but to a certain limit since the miata isn't really designed for long hauls. Roll has been eliminated; it doesn't say in the description but product includes more smiles per gallon. Would buy again if needed.
Had some trouble with another product not being able to fulfill shipment with my schedule due to the move but I was easily able to contact customer service from Good win racing and it was easily resolved.
