Useful info for suspension buyers:

• Rear suspension type – On cars with separate springs, the system can in many cases be built either OEM-style or as a “true coilover” with a pencil-type damper. Let us know your preference when ordering.
• Shimming and spring rates – We can fine-tune your suspension configuration for FAST ROAD, TRACK, or full RACE use depending on your goals.
• R3 series features built-in reservoirs by default. On request, these can be relocated to the engine bay or trunk with custom-length hoses.
• Many kits can be upgraded with adjustable top mounts as an option – ask if needed.
• For many vehicles, an “EDC Delete” kit is available for purchase to properly deactivate the OEM electronic damping system. Note: This is not included by default. If your car has an electronic suspension and you don’t order a delete kit, it may still be possible to code the feature out in your vehicle’s system depending on the model.
