Product Description

These MX5 Springs were chosen by Mazda for their limited edition 2007 MSR package that now dominates the SCCA STOCK CLASS! 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 rate upgrade to keep 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.
