Thank you. You have rated this product.

Adjustable coil-overs allow easy adjustment of ride height and the ability to adjust the weight at each corner. With this simple sleeve design, any shock can now be a race ready coil-over.

Ride height is adjustable from stock to 2" lower and more. All aluminum CNC manufacturing makes for light weight parts with smooth and precise adjustment. Performance shocks are recommended...such as our standard Koni Sport shocks. This is Ground Control's standard kit for the Miata with spring rates of 375 front, 250 rear, fits 90-97, Not Sport Suspension. We recommend our standard koni sport shocks with this standard rate Ground Control kit.

We assume KONI shock application version unless you tell us otherwise!!! Yes, includes all four sleeves, perches, and four springs.

BRIAN'S APPLICATION NOTES: I daily drove this combo for many years. This combo was designed for the dual purpose Miata user, somebody driving their Miata to work and then racing it on the weekend. It's a compromise between full race setups like 700 pounds front, and the stock rates that are well under 200 front. It's a racing combo you can drive every day without getting beat up. Front spring is 6 inches, rear is 7 inches.
