Description
The AST Suspension Lowering Springs for MINI Cooper JCW 2.0L (F66) provide an application-specific lowering solution for owners changing ride height without purchasing a complete coilover system.
The springs determine the installed ride height rather than an adjustable spring perch. Their progressive design changes the effective spring rate through compression, allowing a different response as suspension load increases. Lowering also changes available suspension travel, so damper compatibility and application restrictions matter as much as the advertised drop.
Key specifications
- Approximate lowering from supplied listing: 20 mm front / 15 mm rear.
- Fixed-height lowering springs.
- Manufacturer part number: ASTLS-25-126.
Installation and setup
Compare the exact engine, body style and original suspension specification with the application details before ordering. Stated lowering is approximate; factory sport suspension, vehicle equipment and existing component condition can affect the measured change. Inspect dampers, mounts and bump stops during installation, check tire clearance, and have the alignment measured after the springs settle.
