What to Know Before You Buy
G20 vs G22 vs G26
The G20 is the 3 Series Sedan (2019+), G22 is the 4 Series Coupe (2021+), and G26 is the 4 Series Gran Coupe. The H&R Sport 28662-2 fits all three platforms for 330i, M340i, 430i, and M440i xDrive models. RWD models may have different fitment — verify before purchasing.
Adaptive Suspension Compatibility
M340i and M440i are often equipped with Adaptive M Suspension. The H&R Sport 28662-2 is designed to work with both standard and Adaptive Suspension. If your vehicle has Adaptive M, the springs work with the factory electronic dampers.
330i vs M340i / 430i vs M440i
Spring rates and drop heights are tuned for the shared platform. The same kit fits 330i xDrive, M340i xDrive, 430i xDrive, and M440i xDrive. Drop is approximately 1.2" front and rear. Models with factory sport suspension may see slightly different results.
Alignment & Warranty
A 1.2" drop typically stays within factory alignment specs. Always budget for a professional alignment after installation. G20/G22 models are relatively new; factory shocks should be in good condition for spring-only upgrades.
H&R Sport Springs
The H&R Sport (28662-2) delivers approximately 1.2" front and 1.2" rear drop on the 2019–2023 BMW 330i, M340i, 430i, and M440i xDrive models. It's the primary lowering spring option for the G20/G22 platform, fitting both standard and Adaptive M Suspension. The progressive rate balances daily comfort with improved handling and reduced body roll.
H&R springs are cold-wound from 54SiCr6 steel in Germany. Fits G20 3 Series Sedan, G22 4 Series Coupe, and G26 4 Series Gran Coupe. The universal fitment across 330i, M340i, 430i, and M440i xDrive makes it the go-to choice for G20/G22 owners.
