AST G80 M3 Sport Spring Kit - ASTLS-21-080

Give your BMW M3 G80 the stance and composure it deserves. This AST progressive coil spring set is tailored to the G80 chassis for 2020 onwards models, including Competition and xDrive variants. Expect a purposeful ride height drop, tighter body control, crisper steering response and impressive stability on British roads, all while keeping day-to-day comfort with the factory dampers.

Manufactured from cold coiled, high tensile chrome-silicon spring steel, these performance springs deliver durability and consistency you can trust. Direct-replacement fitment means they work seamlessly with stock shock absorbers, offering a clean, reversible upgrade for drivers who want a sharper drive and a level, aggressive look without compromising usability.

Ride height reduction

• M3 non-Competition - Front 30 to 32 mm, Rear 20 to 25 mm
• M3 Competition - Front 25 mm, Rear 10 to 15 mm

Note: Figures are a guide and vary with options, trim level and equipment. Vehicles already on sport suspension typically achieve a smaller drop.
