Setup and installation
Spring rates and mounting parts are selected for the application. Have the kit installed and aligned by a suspension specialist. Check wheel, tyre and body clearance through the full steering and suspension travel, and follow the instructions supplied with the kit.
Ordering and lead time
This kit is made to order. The supplier currently advises an approximate four-week lead time, but this can change. Contact GSM Performance before booking installation if timing is critical.

Will this fit my car?
This listing is for the Subaru Impreza WRX GD, Impreza WRX GG, Impreza WRX STI GD and the other models listed. Chassis code, model year, engine and drivetrain all matter, and MOTON often use different part numbers for cars that look the same, so check your car against the vehicle table in the description. If anything is unclear, send us your registration or VIN and we will check it before you order.
What can I adjust?
The MOTON 1-Way Clubracer is a monotube coilover with 15-position rebound adjustment, and the ride height is adjustable too.
What comes in the kit?
Coilovers front and rear. Camber-adjustable front and solid rear top mounts are included where applicable. Springs are included.
How low will it go?
The height is set on the threaded body. How low it sits in practice depends on your wheels, tyres and how much bump travel you keep. Our guide Ride Height, Preload And Getting A Coilover Setup Right explains how to set it without running out of travel.
Is it right for road or track?
It depends how much of your driving is on track. Our guide Fast Road Or Track: Choosing The Damping On A Set Of Coilovers explains what 1-way, 2-way and 3-way adjustment gets you.
Can I fit it myself?
Our guide Fitting Coilovers At Home Or Having Them Done covers what the job involves. Either way, have the wheel alignment checked after fitting and check wheel and tyre clearance through full steering lock and suspension travel.
Can they be rebuilt?
Yes. AST and MOTON dampers are rebuildable through an authorised AST x MOTON service centre, and how often depends on how hard the car is used. Ask us and we will point you in the right direction.
How long does it take?
Each kit is made to order and the supplier currently quotes about four weeks. That can change, so if you have a fitting date booked, ask us before you order and we will confirm it.
