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. This is version for factory BILSTEIN shock Sport Suspension (and these ONLY fit the Bilsteins so if you don't have the Bilsteins on the car at this point then order another choice...). Base CSP kit 375 front, 250 rear, 99-05, Sport Suspension version!

We can do CUSTOM spring rates on request!

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.

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,

Good morning Brian, I finally got a chance to put the exhaust on, great advice, it's just loud enough, solid product. I'm running without the baffles, sounds great in power band. Take care, you have all my future upgrade business.........regards.
