Description

Customize your Pro-C or Pro-S II Coilovers for the perfect balance between daily driving and track performance. Skunk2 Race Springs for Pro-C or Pro-S II Coilovers allow you to fine tune handling performance and driver feel through customized spring rates and ride heights. All Skunk2 Race Springs are CNC-wound using the highest quality SAE 9254V spring steel, shot-peen stress relieved, and corrosion-protected thanks to powdercoating and specialized phosphate treating processes.

Product Overview

Skunk2 race springs are available separately giving the experienced tuner more freedom in designing custom suspension set-ups. These are the same springs that come standard in each Skunk2 Racing adjustable coilover kit. Available as straight, elliptical, or cone tapered in numerous lengths and rates - you can be sure that perfect suspension setup is just a step away. How to read part # on spring: Example 0500.250.008 * 0500: (length of spring = 5") * 250: (inner diamater of spring = 2.50") * 008: (spring rate = 8kg/mm) Spring Rate Conversion: 1 kg/mm = 55.88 lb/in
