Thank you. You have rated this product.
These springs have been designed with a rate increase of approximately 20% (front - 145 lb/in) and 20% (rear - 112 lb/in) with a modest drop of 1-inch (front and rear).
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 or Koni performance shocks. Although the ride quality will become noticeably firmer, the handling improvements will be a much-welcomed improvement.
These springs are available separately for replacement or special applications: Front (PN 14018) or Rear (PN 14019) - contact Racing Beat for ordering information.
