E93 convertible and non-M3 applications require separate checks.

Confirm the actual supplied mounts and rear spring arrangement before ordering. Spherical or rigid mounts can transmit more noise and vibration than rubber mounts, which matters on a road-driven M3.\u003c\/p\u003e\u003ch2\u003eDevelop the damping setup\u003c\/h2\u003e\u003cp\u003eIndependent compression and rebound controls are useful with a defined tyre, spring and alignment baseline. Reservoir placement and hose clearance must suit the installation. A particular lowering figure cannot be guaranteed without checking the starting ride height, travel and selected build.\u003c\/p\u003e\u003cp\u003eNitron R3 dampers are serviceable.
