Dinan Lightweight Tubular Anti-Roll Bar Set for BMW M2 M3 and M4

Dinan's lightweight tubular anti-roll bar set (D120-0605) replaces the front and rear bars on the F80 M3, F82/F83 M4, and F87 M2. The factory bars are sized for comfort. These hollow bars are larger—32 mm in front versus a 24.7 mm stock bar, and 24 mm in the rear versus 22.9 mm—so they cut body roll and add mechanical grip without the weight of a solid bar of the same size.

The front bar is adjustable from 57% to 103% stiffer than stock. It has four holes and, with the supplied adjustable end links, can be mounted in seven positions. The rear bar is adjustable from 0% to 13% stiffer than stock. It has three holes and three positions and uses the stock BMW end links. Dinan quotes 7 hours of labor. Emission code 6 applies. The published package is 44 x 10 x 4 inches at 30 pounds.

Dinan titles the set for 2015-2020 M2, M3, and M4 cars on chassis F80, F82, F83, and F87. The US table below cuts those years by model: F80 M3 through 2018, F82/F83 M4 through 2020, and F87 M2 from 2016 through 2020, which includes the M2 Competition and M2 CS years that fall inside Dinan's 2015-2020 window. The later 2021 M2 Competition year that appears on some dealer lists is not added, because Dinan's title ends in 2020. The M3/M4 store page and the later DNN-prefixed listing share this part number and redirect here.

Coverage follows Dinan's standard limited warranty: the remainder of the vehicle factory limited warranty (up to 4 years / 50,000 miles) or 2 years / unlimited miles, whichever is greater.
