AST BMW G87 M2 / G80 M3 / G81 / G82 M4 / G83 M4 Adjustable Lowering Springs - 20-46mm Fr / 10-36mm Rr
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2021-2023 BMW M3 and M4 (Base, Competition, and Competition xDrive).
AST Adjustable Lowering Springs provide the flexibility to fine-tune your vehicle's ride height even after installation, offering a significant upgrade over fixed-height springs. By lowering the center of gravity, these springs reduce body roll and improve handling dynamics while maintaining the comfort of the factory electronic dampers. Each spring is precision-engineered and cold-coiled on advanced Wafios machines, utilizing a progressive rate design to balance daily drivability with a track-ready stance.
Designed as a direct replacement for the original equipment, these springs allow for precise corner-weighting or aesthetic adjustments to suit your wheel and tire fitment. Developed and manufactured in the Netherlands, they represent the pinnacle of suspension tuning for the BMW G-chassis platform.
- Front Lowering Range: 20-46mm
- Rear Lowering Range: 10-36mm
- Spring Design: Progressive rates for performance and comfort
- Manufacturing: Cold-coiled on Wafios coiling machines
- Installation: Direct OEM replacement, compatible with factory dampers
