SP x Nitron R3 Coilover Kit – BMW F80 M3 / F82 M4
SP x Nitron R3 coilovers for BMW F80 M3 / F82 M4 combine Nitron's 3-way R3 platform with a Swift Performance specification developed around the BMW M chassis.
The kit uses optimised damper dimensions, Swift-specific valving and Swift-specific spring rates, together with a true-coilover rear layout and remote rear reservoirs with Nitron Dry Brake quick-disconnect couplings and the Bi-Axis hose system. Each SP kit is laser etched on the front and rear dampers.

Ordering and specification
Specification: supplied in the Swift Performance SP specification for this chassis.
Nitron Dry Brake remote reservoir system
The SP R3 rear dampers use Nitron's Bi-Axis Hose and Dry Brake system for the remote reservoirs. The quick-disconnect arrangement allows the reservoir hoses to be routed cleanly through existing factory passages, avoiding the need to drill or modify the vehicle bodywork simply to pass the reservoir line through.
The reservoirs can then be mounted in accessible locations using OEM hardpoints, keeping the installation neat while leaving the compression adjusters convenient to reach during setup.
Developed by Swift Performance with Nitron
SP x Nitron is a direct result of our ongoing BMW development work with Nitron. For each SP application we use Swift-specific damper dimensions, valving and spring rates together with the true-coilover rear layout and remote rear reservoir arrangement that define the range.
Development has included road and workshop use plus circuit testing at the Nürburgring, Spa-Francorchamps and UK circuits. Because the specification is ours, we can advise from first-hand experience, supply the kit for delivery, or install it in-house including reservoir positioning, ride-height setup, four-wheel alignment and an appropriate baseline damper setup.
Frequently asked questions
What is different about the SP x Nitron specification?
The SP range uses Swift Performance damper dimensions, valving and spring rates developed around BMW M platforms, with a true-coilover rear layout and remote rear reservoirs using Nitron Dry Brake quick-disconnect couplings and the Bi-Axis hose system.
Why does the SP R3 use Nitron Dry Brakes?
The Dry Brake quick-disconnects form part of Nitron's Bi-Axis Hose system. They allow the remote-reservoir hoses to be routed through existing factory passages without unnecessary bodywork modification, while the reservoirs can be positioned at accessible OEM hardpoints for adjustment.
Does the kit include top mounts and drop links?
Yes. SP BMW M applications include adjustable front top mounts and adjustable drop links.
Can Swift Performance fit the kit?
Yes. We can install the kit, position the reservoirs, set ride height and complete the wheel alignment.
