- Note: Does not fit any G20 equipped with factory EDC (Electronic Damper Control / Adaptive M Suspension). If your 3 Series has a suspension mode selector or comfort/sport/adaptive damping settings controlled electronically, it has EDC and these coilovers are not compatible
- Note: These are performance lowering coilovers. They only lower from factory height. You cannot raise the car or maintain OEM height with these coilovers
Fitment Note: These coilovers fit the G20 3 Series across all non-M body variants and engine options from 2019 through 2025 in both RWD and xDrive configurations, excluding any model equipped with factory EDC. EDC was available as a standalone option and as part of the Driving Assistance Professional Package on several G20 trims, so confirm your car's suspension setup before ordering. An alignment is required after installation. Sold as a complete set of 4 coilovers.

The G20's double wishbone front and multi-link rear suspension is one of the better platforms for a coilover conversion since the geometry adjustments are meaningful and the car responds well to being lowered. The camber plates up front let you dial in camber directly at the alignment shop rather than relying on eccentric bolts or shims. The 32 clicks of simultaneous compression and rebound give you a genuine range from comfortable daily driving to a stiffer, more planted setup without being a chore to adjust. If you ever want to push these further, Riaction rebuilds and upgrades them in the USA rather than requiring a return overseas.

- TruHart Rear Camber Arms BMW 3 Series G20 / G21 RWD and AWD (2019-2020) The G20's rear suspension shifts camber out of spec once the car is lowered and the factory arm has no way to correct it at the alignment rack. These TruHart rear camber arms give your alignment shop the adjustability to dial the rear geometry back in after the coilovers go on.
