Adding a larger sway bar reduces body roll and puts the tire in better contact with the road. This is the H&R 25mm rear sway bar for the 2015+ F87 M2, F80 M3, and F82 M4.

Adding a larger rear sway bar is done to make the rear end rotate easier in a corner. This gives the car more oversteer, especially with heavy throttle input (i.e. - drifting, sliding). Larger rear swaybars are used in track events like autocross or on very tight circuits where the bigger bar is needed to avoid understeer in slower corners. It's not very common to add only the rear bar for street use as too much rear bar will make the car feel nervous and tail-happy. Changing rear bar sizes is common on track cars to find the best handling balance in combination with a larger front swaybar. This rear bar is not adjustable.

H&R designs and manufactures their sway bars in Germany from very high quality spring-grade steel. Each bar is shot-peened and hardened for added strength and powder coated for corrosion resistance. H&R's exclusive sway bar bushings are made from a special polyurethane and Teflon composite material that eliminates the need for lubrication and prevents squeaks. No mess, no noise, no maintenance, and perfect fit.
