Description

BMW F80/F82 M3/M4 3-bolt True Rear (14-20) BC Racing DS coilover kit 6/6 kg/mm

The BC Racing DS coilover kit M3 M4 F80 3-bolt True Rear (part number I-132-DS-DH) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M3 F80 and M4 F82 with front top mounts secured by 3 bolts, model years 2014 to 2020, in True Rear version. The spring rate is 6 kg/mm front and 6 kg/mm rear.

The DS series is BC Racing’s track-focused coilover kit. The monotube dampers have a digressive piston that damps more firmly during slow body movements, between 0 and 50 mm/s; this keeps an M3 or M4 calmer on turn-in and during load changes, while the kit remains usable on the road.

This version is True Rear: the spring also sits around the damper at the rear, whereas the standard DS kits for the F80 and F82 keep spring and damper separate at the rear. The kit fits cars with front top mounts secured by 3 bolts and has pillowball top mounts or camber plates front and rear. The damper body is finished in satin chrome.

Key benefits

• Digressive piston: firm damping during slow body movements (0 to 50 mm/s).
• True Rear: a complete strut at the rear with the spring around the damper.
• 3-bolt front top mounts: for the M3 F80 and M4 F82 with this mounting on the strut tower.
• Pillowball top mounts front and rear: or camber plates, on all four corners.
• 30-click damping adjustment: compression and rebound together, per damper.
• Ride height independent of the spring preload: lower the car without adding extra preload to the spring.
• Concave lower lock ring: locks the set height firmly in place.
• Satin chrome damper body: the recognisable finish of the DS series.
• Rebuildable: the dampers can be rebuilt.

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. Please note: BC Racing specifies that the body shell must be reinforced before a True Rear kit is fitted. Before you order, count the bolts of the front top mounts: this kit is for the 3-bolt version. After setting the ride height, have the alignment checked and recorded; for track use, a careful camber and toe setup pays off. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. No stock at the manufacturer? You can still order and we will let you know when the kit is shipped.

For the BMW M3 F80 and M4 F82 with 3-bolt front top mounts, BC Racing supplies the DS True Rear kit I-132-DS-DH, with a digressive piston, 30 clicks of damping and 6/6 kg/mm springs.

Why choose this DS coilover kit M3 M4 F80 3-bolt True Rear?

An M3 or M4 that regularly goes on track needs damping that keeps the body calm during quick changes of direction. The digressive piston of the DS does exactly that, and with True Rear you also set the ride height at the rear via the coilover kit. The dampers are rebuildable, so after a few seasons of track work you can have them rebuilt.
