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. Hardcore CSP kit, 99-05, Not Sport Suspension. These drop ship direct from Ground Control and they consider this spring combo a custom order spring rate which means you should assume about two weeks ordering time! WE ASSUME YOU WILL INSTALL THESE ON KONI shocks unless you tell us otherwise.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

The Konig Lightspeeds are incredible. Perfect and the best price in the market. Thanks Chris and Robbie
