Get the heights RIGHT for your NC2 Generation MX-5.

Too many spring makers did not adjust their springs after NC2 MX-5 arrived starting in 2009, the springs from those other guys end up with back end low and front end relatively high. That dreaded 'Speedboat' effect is avoided by these springs made specially for the 2009-2015 MX-5, after a few thousand miles on our Project PRHT 2012 they settled to 13.5 front and about 13.8 rear (your results may vary depending on which shock you use and the age of the shocks, as shock pressure declines over time the car will settle lower).

The engineering staff at Progress has decades of experience in the design and tuning of performance suspension systems, including CART/Indy Cars, IMSA, SCCA, NASA, and SCORE competitors. These MX5 springs reflect their ability to develop a successful blend of appearance, handling capability, and ride quality.

These MX5 springs feature increased spring rates for upgraded handling capabilities with reasonable rates to maintain superior ride quality. These MX5 springs are designed to work with OEM shocks but will benefit from using high performance shocks such as our adjustable choices from Koni and Tokico. Progress specifies only certified high-tensile SAE spring wire materials. Their MX5 springs are cold-wound on modern CNC coiling machines, then stress relieved, pre-set, and shot-peened for maximum durability.
