MMX Performance G8X M2 / M3 / M4 Height Adjustable Spring Kit

Unlike conventional fixed-drop lowering springs, the MMX Height Adjustable Sport Spring Kit (HAS) gives you a fully customizable ride height across the full range of factory G-chassis M-Cars. The kit is engineered specifically for the G80 M3, G81 M3 Touring, G82 M4, G83 M4 Convertible and G87 M2, covering the full G8X family in a single product.

The adjustable design pairs MMX-developed sport springs with billet height-adjustment hardware, giving you 20-45mm of lowering range at the front and 10-35mm at the rear versus factory ride height. That means whether you want a subtle daily-driver drop or an aggressive track-day stance, you can dial it in without buying a different spring set.

Front and rear are independently adjustable, so you can fine-tune corner balance and rake to your exact preference. The sport-rate springs improve dynamic response over the OE setup (sharper turn-in, less roll, more direct mid-corner feedback) while remaining fully compatible with both static and Adaptive M dampers.

The end result is a single suspension upgrade that adapts to how you drive: lifted slightly for daily use and clearance, or dropped fully for a planted track-day stance, without the cost or complexity of a full coilover setup.
