The Eibach PRO-KIT is a lowering spring set built on the manufacturer's progressive spring technology, aimed at the BMW G80 M3 generation. Eibach describes the PRO-KIT line as a way to lower a car's stance while keeping ride quality close to stock, which is the main reason to choose it over a generic drop spring. Owners who want a tighter front fender gap on the G80 M3 are the buyers this line is designed for. Confirm the exact configuration of this part number before ordering, because Eibach's G80 M3 PRO-KIT listings include both front-only and front-and-rear sets.
Eibach says its PRO-KIT springs are meant to lower the center of gravity, which can reduce squat under acceleration, body roll in corners, and nose-dive under braking. Searches for G80 M3 Pro-Street springs, BMW G80 M3 progressive lowering springs, and M3 fender gap springs will lead to this kit. Because the springs are designed to be used with the factory dampers, the install is a spring swap rather than a full suspension rebuild, though you should still get a professional alignment afterward. Check the M3 trim (RWD, Competition, or Competition xDrive) against the manufacturer's fitment chart before purchasing.
