What is rebound adjustment and how does it affect my car?

Rebound adjustment controls how quickly the shock absorber extends after being compressed. With 12 positions, you can fine-tune this return speed to achieve your desired road balance and handling characteristics, whether for track use or daily driving.

Can I adjust the spring rates with this kit?

Yes, you have the flexibility to adjust spring rates on these dampers. The initial setup and spring rates are based on extensive development and testing by AST.

Are these coilovers rebuildable?

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

About this part

Product Details

The AST 5100 CLUBRACING SUSPENSION set is built for 1989-1994 Porsche 911 models. These coilovers let you fine-tune your car's grip and handling, whether you're hitting the track or want a better balance for daily driving. They offer adjustability in both rebound damping and ride height.

These are monotube dampers, which means they have a large piston for better control over rebound adjustments. Monotube designs also prevent aeration and foaming, leading to more responsive valving. The dampers are also rebuildable at a certified AST service center.
