How do I adjust the ride height and rebound on these coilovers?

You can adjust the ride height by altering the spring perch position. The rebound damping is adjusted using the knob on the top of the damper, with 12 distinct positions available to fine-tune the suspension's return rate.

What is the benefit of a monotube damper design?

Monotube dampers use a large piston and have no aeration or foaming. This results in more responsive valving and consistent damping performance, especially under demanding conditions.

Can these coilovers be rebuilt if they wear out?

Yes, these AST dampers are rebuildable. If any issues arise, they can be serviced at a certified AST service center.

Product Details

You get front and rear dampers, springs, and top mounts in this AST 5100 Clubracing coilover package for your 1999-2005 Acura NSX. These are built for track use but can be set up for a good road balance. They let you fine-tune grip by adjusting how the suspension returns after hitting a bump, and you can also change the ride height. This setup prioritizes adjustability and performance.

The monotube design uses a large piston to control rebound damping. This means no air gets mixed into the fluid, so the damping is more responsive. These dampers can be rebuilt at a certified AST service center if needed. The package includes camber-adjustable front top mounts and solid rear top mounts, which let you adjust front-end geometry for better grip.
