Additional Notes

• Customize at your own discretion. Please ensure you are selecting the right specs when customizing your coilovers.
• We highly recommend ensuring your struts are properly valved to match your chosen spring rates. If you’re increasing or decreasing spring rates by 4k or more, it’s best to revalve your struts accordingly. Failing to properly match your springs and struts can lead to coilover damage, reduced performance, a noticeably harsher ride, and may void the warranty.
