H&R Super Sport Spring Kit – BMW M3 (G80, S58)

OVERVIEW

Suspension is one of the biggest factors in how a car drives day to day, and upgrading the stock springs is the first step in suspension tuning. H&R Super Sport Springs for the G80 M3 and M3 Competition drop the car about 1.4" at the front and 1.0" at the rear, reducing body roll and improving handling while keeping the ride comfortable.

Super Sport Springs carry all the features of H&R Sport Springs plus additional lowering, with a progressive rate design that stays composed under load without turning the car harsh on the street.

H&R Special Springs will not set or sag. They are crafted from a special (hf) 54SiCr6 spring steel and shot-peened to increase their life by more than 200%. All production is completed in-house, and each spring is 100% tested before leaving H&R's ISO9001-certified production facility in Germany.
