MINI (2002-Current)

Those who used to, or still, own the older gen MINIs know how much of an improvement they get from 22mm Solid Rear Anti Sway Bar. It is essentially the best body roll management you can ever do to your MINI. The handling characteristic and steering input are so well enhanced it is almost as good, if not better, compared to installing lowering springs or coilovers.

Fits the following models:

2014-2021 F56 MINI Cooper and Cooper S Hardtop
2015-2021 F55 MINI Cooper and Cooper S Hardtop 4-Door
2016-2021 F57 MINI Cooper and Cooper S Convertible

Also compatible with the F56 GP!

Front wheel drive cars naturally understeer from the factory, including the MINIs. The NM Engineering Solid 22mm Rear Anti Sway Bar improves your F-chassis MINI by inducing more oversteer and increasing the car handling predictability.

NM Eng Anti Sway Bar features:

  • mandrel bent solid chromoly bar providing consistent diameter through out for precise torsion motion
  • forged ends (not cheaply welded plate) with two adjustment mounting holes 
  • graphite impregnated urethane bushing
  • glossy blue powder coat finish

The two adjustment mounting holes provide 3 levels of stiffness:

  • stiff = both ends at forward holes
  • soft = both ends at rear holes
  • medium = one at forward and one at rear hole

When ordering this sway bar, we STRONGLY recommend the G3NMS2105 Adjustable Drop Links (End Links) since the factory drop links are made from plastic and may not be up to the task with this performance sway bar upgrade.

Another option is the G3NMS2110 22mm Billet Sway Bar Brackets which are much more durable AND includes a zerk fitting to allow lubricating.

We at Mini Mania believe the rear anti-sway bar should be the first suspension upgrade on your MINI.  Of course, we also recommend that you drive your MINI in a drivers education event before modifications to truly learn the characteristics of this fabulous car.  Then you can appreciate the improvements you get from each of these upgrades.
