MMX Lowering Springs for F40 BMW M135i
BMW M135i lowering springs from MMX Performance deliver the ideal balance of improved handling, refined aesthetics, and everyday ride comfort for the F40 M135i (2020-2024). The factory M135i carries a noticeable nose-up rake from the factory, with more front wheel gap than rear, which undermines the visual aggression the car’s performance intent deserves. The MMX BMW M135i lowering springs address this directly: a 25mm front drop and 20mm rear drop eliminate the factory rake, giving the car a balanced, level stance that closes up the wheel arches and lowers the center of gravity simultaneously. Carefully selected progressive spring rates enhance dynamic response, reducing body roll, sharpening turn-in, and improving mid-corner stability while preserving compliant ride quality at lower speeds so the car remains genuinely comfortable for daily use. Fully compatible with both static and Adaptive M dampers across all drive modes, requiring no recalibration after installation.

Frequently Asked Questions
- Why is the drop asymmetric on the BMW M135i lowering springs? The F40 M135i has more front wheel gap than rear from the factory, creating a nose-up rake that looks mismatched with the car’s performance character. The MMX BMW M135i lowering springs use a 25mm front and 20mm rear drop specifically to eliminate that rake and give the car a balanced, level stance rather than simply lowering it uniformly.
- Are the BMW M135i lowering springs compatible with the Adaptive M damper? Yes. The BMW M135i lowering springs are engineered to work with both static OEM and Adaptive M dampers, keeping every drive mode fully usable after installation with no recalibration required.
- Will the BMW M135i lowering springs make the ride harsh? No. The progressive spring design retains low-speed compliance for everyday comfort while firming up progressively under load, so the car feels more composed in dynamic driving without becoming punishing on imperfect roads.
- Do the BMW M135i lowering springs require new dampers? No. This is a pure spring-only upgrade that replaces the factory springs at the existing mounting points with no damper changes, no modifications, and no additional hardware required.
- How much improvement in handling does a 25mm drop actually deliver? Lowering the center of gravity by 25mm front and 20mm rear meaningfully reduces body roll in corners and sharpens turn-in response, as the car’s mass shifts less during direction changes. Combined with the progressive spring rates, the BMW M135i lowering springs improve mid-corner stability and overall agility while retaining the compliance the F40 platform is known for at everyday speeds.
