Description

BMW F80/F82 M3/M4 5-bolt True Rear (14-20) BC Racing DS coilover kit 6/6 kg/mm

The BC Racing DS coilover kit M3 M4 F80 5-bolt True Rear (part number I-133-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 5 bolts, model years 2014 to 2020, in True Rear version. The spring rate is 6 kg/mm front and 6 kg/mm rear.

With the DS you choose BC Racing’s track-focused line: monotube dampers with a digressive piston, 30-click adjustment and a satin chrome damper body. The digressive piston damps more firmly during slow body movements (0 to 50 mm/s), which makes an M3 or M4 calmer through fast sequences of corners.

This True Rear variant is for cars with front top mounts secured by 5 bolts and also has the spring around the damper at the rear. Pillowball top mounts or camber plates are fitted front and rear, and you set the ride height independently of the spring preload.

Key benefits

• For 5-bolt top mounts: fits the M3 F80 and M4 F82 with this front mounting.
• Digressive monotube: more damping during slow body movements between 0 and 50 mm/s.
• True Rear: the rear gets a complete strut.
• Pillowball or camber plate all round: the same construction front and rear.
• 30 clicks: compression and rebound adjusted together.
• Ride height independent of the spring preload: lower the car while the preload stays the same.
• Concave lower lock ring: locks the set height.
• Rebuildable: the dampers can be rebuilt.

Suitable for

BMW M3 F80 Sedan and M4 F82 Coupe with rear-wheel drive, model years 2014 to 2020, with front top mounts secured to the strut tower with 5 bolts, in True Rear version. If the front top mounts are secured with 3 bolts, choose the I-132 kit. The M4 Convertible (F83) is not listed by BC Racing; please contact us for that version.

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 ordering, check whether the front top mounts are secured with 5 bolts. After setting the height, have camber and toe adjusted again, especially if you use the car on track. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the manufacturer does not have the kit in stock, you can still order and we will let you know when it is shipped.

Why choose this DS coilover kit M3 M4 F80 5-bolt True Rear?

The DS is made for drivers who like to use their M3 or M4 on track but also drive it home. Thanks to the digressive piston, the body stays calmer on turn-in and during load changes, and with True Rear you also set the height at the rear via the coilover kit. After a few seasons you can have the dampers rebuilt.
