Overview

These coilovers are engineered with the factory suspension geometry, shock dampening, spring rate, and ride height levels in mind, ensuring they are made specifically for your car for both performance and comfort. They are hand-assembled Monotube systems that improve ride quality, performance, and comfort.

Show original supplier description

The coilovers are built with an emphasis on minimizing adjustment time at the track, allowing drivers to go from street to track and back home comfortably. They incorporate Urethane bushing technology instead of bearings to reduce vibrations and noise from suspension movements, and use roller bearings on MacPherson type suspensions to eliminate spring twist noise. Rubber padding is also used to help eliminate potential noise from suspension movements. These coilovers offer up to 36-way adjustable damping for tuning shocks' compression and rebound to individual needs and driving conditions. For refined camber tuning, select vehicles feature upper mounts that can add 1.5 degrees of camber by rotating the plate. The front lowering adjustment range is +5-90mm, and the rear is 0-55mm. The product is listed as a Coilover Part Type.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
