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.

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
