Spring Rate Options – Tuned by Nitron for the BMW F82 M4
Each NTR R1 kit is supplied with carefully chosen spring rates and damper lengths, refined through real-world testing on the F8X chassis. These configurations are ideal for performance-oriented road use and trackdays.
Choose from two optimised setups:
Fast Road Setup
Well-suited for fast road use and occasional circuit driving.
-
Front: 120 N/mm
-
Rear (Divorced): 130 N/mm
-
Rear (True Coilover): 70 N/mm
Track Setup
For track-focused builds requiring increased stiffness, improved feedback, and minimal body roll.
-
Front: 140 N/mm
-
Rear (Divorced): 160 N/mm
-
Rear (True Coilover): 90 N/mm
True rear spring rates appear lower due to different mounting ratios and spring positions – overall stiffness is comparable.
Custom Options Available
Custom spring rates, spring lengths, and damper lengths are available on request. Contact us before ordering to have your kit tailored by Nitron to your specific needs.
True vs Divorced Rear – What’s the Difference?
True Rear Setup
A single coilover unit combining spring and damper – ideal for track-focused builds and maximum performance.
Divorced Rear Setup
Uses the factory-style separate spring and damper layout – easier to install and retains OEM suspension geometry.
Which Should You Choose?
-
Choose True Rear for adjustability, precision, and outright performance
-
Choose Divorced Rear for simplicity and ease of install in factory-style builds

Bought the Infinity Design S65 Modular Carbon Plenum for my E9X M3. The finish is excellent and it completely transforms the look of the engine bay. It feels like a properly engineered piece rather than just a cosmetic upgrade. Really pleased with how it looks once fitted.
-
I went with the Endless MX-72 Plus Brake Pads for my G8X and they've been a great upgrade. The pedal feels positive and the pads give plenty of confidence when braking hard. They also work well for normal road driving, which was important to me. CPC Clubsport made the whole ordering process easy.

Had the Nitron NTR R3 Coilovers fitted to my E9X M3 and the difference is impressive. The car feels much more controlled and planted, particularly through faster corners. The adjustability is a big advantage as well, allowing the setup to be tailored to how I use the car. Excellent upgrade for a car that sees both road and track use.

Fitted the Ferodo DS1.11 Brake Pads F8X (Front) to my F82 M4 and they've been excellent. The initial bite is strong and the braking feels much more consistent when pushing the car hard. They’re particularly impressive on track where the brakes stay predictable through repeated heavy braking zones. Very happy with the purchase and service from CPC Clubsport.
