Product Description
Swift Spec-R lowering springs give the 2023-2025 BMW M2 G87 a lower, more settled stance with an even 1.3-inch drop at the front and rear. They are a fixed-height spring option for M2 owners who want to reduce the factory wheel gap while keeping the car on a conventional spring-and-damper setup.
The 4X931R set uses a 5.0 kgf/mm front rate and 13.0 kgf/mm rear rate, selected specifically for the G87 chassis. It is a straightforward suspension upgrade for street-driven M2 builds, track-day cars, or owners looking to improve the appearance of the car before moving to a fully adjustable coilover system.
Before You Buy
This is a fixed-height lowering spring set, not a height-adjustable suspension system. The kit lowers the M2 approximately 1.3 inches at both ends. After installation, have the alignment checked and confirm tire, wheel, and fender clearance at full steering lock and suspension compression, especially if the car uses aftermarket wheels or spacers.
Popular Performance Upgrades for Your G87 M2
- Eibach Pro wheel spacers for BMW M2 G87 can help bring the factory wheels closer to the fender after lowering. Select spacer thickness and required hardware based on your wheel-clearance goals.
- IRL V2 stainless axleback exhaust for BMW G87 M2 adds a more distinctive rear-end presence to a lowered G87 build while retaining vehicle-specific fitment.
