These springs have been designed with a rate increase of approximately 30% (front - 157 lb/in) and 20% (rear - 106 lb/in) with a modest drop of .33-inch (front) and 1-inch (rear). (As compared to a Miata equipped with a manual transmission.) On 1993 models equipped with Bilstein sports package, these springs will lower the rear approximately .75-inch. Although this lowering combination may seem rather "odd", the final appearance of the springs on the car offers a balanced "front to rear" look.

If your car is still running on the original shocks, it is certainly time to consider a replacement! We do not suggest installing aftermarket performance-based springs on a set of tired high mileage shocks, as this may produce a "springy" and bouncy ride. If you prefer to keep the ride quality of your car more "stock like", you may wish to replace your old shocks with a set of Mazda units, or an equivalent set of aftermarket OEM style replacements. However, if you wish to noticeably improve the handling performance of your car, combine a set of new springs with a set of aftermarket Tokico, Koni, or KYB performance shocks. Although the ride quality will become noticeably firmer, the handling improvements will be a much-welcomed improvement.

Price shown is for a complete set of four (4) springs.
