The Nitron NTR R1 coilover kit for BMW G82 M4 Competition xDrive provides single-adjuster suspension for road and occasional track setup.

Key features and intended use

  • Combined compression and rebound adjustment simplifies damper setup.
  • Spring specification can be chosen for road use or a stronger track bias where listed.
  • Allows a suspension setup to be matched to use without the separate compression controls of R3.

How to choose the setup

Choose the spring package around tire grip, track frequency and the intended ride quality. FRS means Fast Road Specification; TDS means Track Day Specification. These are spring/build choices, not electronic driving modes. The supplier base part number alone does not capture every ordered configuration.

Coilover or divorced rear springs

A divorced rear arrangement keeps the spring separate from the damper. A rear coilover places the spring around the damper. Select the intended rear layout in the options; it is an installation choice rather than a cosmetic preference. Have the installer check the load path, mounts, spring clearance and travel for the selected arrangement.

Factory electronic damping

This is a manually adjusted suspension kit. If the car has factory electronically controlled dampers, confirm the appropriate cancellation or conversion hardware with the installer. The listing should not be interpreted as retaining factory electronic damper adjustment.

Installation and ordering

Provide the model year, chassis, factory suspension equipment and intended use when specifying the order. Have the installer verify the mounts, usable travel, wheel clearance and any required electronic hardware. Confirm lead time for the selected configuration; catalog availability is not a promise of immediate dispatch.

Product FAQs

Can I adjust compression separately from rebound on R1?

No. Manual NTR R1 uses a combined adjustment. R3 provides independent controls if separate tuning is a priority.

What should I evaluate before changing the damping setting?

Start with tire pressures, alignment and a consistent baseline. Assess one change at a time rather than using damper adjustment to compensate for an unresolved chassis issue.

Can I use the rear-wheel-drive listing for my xDrive car?

Use the application that explicitly identifies xDrive. Do not establish compatibility from the G80 or G82 chassis name alone.
