MINI did a wonderful job with the handling on the new 3rd generation F-series MINI, but their design is on the conservative side to appeal to the widest segment of the market. This leaves room for improvement for the 'enthusiast' type driver.

When we talk about 'improving' the suspension, we always begin with a larger rear sway bar. This upgrade reduces the inherent 'understeer' built into the car for safety and provides a more 'balance' car. This allows you to carry more speed into and out of the corner while keeping the car 'flatter' in the corners. The Adjustable Drop Links replaces the factory 'plastic' units for reliability and adjustability.

The KW Coilovers lower the center of gravity and keeps the tires planted on the road. They are height adjustable with some versions offering variable damper settings.

Anytime the MINI is lowered, the rear negative camber is greatly increased and needs to be corrected. This is the reason for the Adjustable Rear Control Arms included in this kit. This kit includes a pair of the adjustable arms which will allow you to optimize the rear alignment.

KW COILOVERS - Variant 1

Sporty, Balanced with KW factory pre-set dampening

The ideal system for customers wishing to rely on the experience of our engineers to set the damper setting, yet determine their own degree of lowering. In extensive driving tests our engineers have set the dampers for the best balance between sporty driving, comfort and safety. The user is then free to decide the best height setting for their use and preference.


  • Optimally adjusted, sporty and comfortable dampening technology
  • Inox-line stainless steel technology at no extra charge
  • Individually height adjustable
  • German TUEV-tested lowering range
  • High-quality components for long life
  • Comprehensive documentation for ease of use

Front: 0.8" to1.8"
Rear: 1.2" to 2.6"


Front wheel drive cars naturally understeer from the factory, even the MINIs. The NM Engineering 25mm Rear Anti Sway Bar improves your F-chassis MINI by improving rotation and increasing the car handling predictability.

NM Eng Anti Sway Bar features:

  • mandrel bent solid chromoly bar providing consistent diameter through out for precise torsioning motion
  • forged ends (not cheaply welded plate) with two adjustment mounting holes
  • billet 7075-T6 aerospace grade sway bar bracket
  • 90° Zerk fitting for ease of re-greasing
  • graphite impregnated urethane bushing
  • glossy blue powder coat finish
  • 3-way adjustable preload


MINI cuts cost by equipping the new F55/56 with links made from plastic. It may be sufficient for factory 17-18mm hollow bar but it will not perform optimumly when paired with the larger 22mm Solid Anti Sway Bar. NM ALL METAL Sway Bar Links are far more superior by providing these following benefits:

  • Replacement of factory weak plastic links
  • Provide direct sway bar feedback
  • Adjustable to 15mm shorter than factory length to accomodate extreme suspension drop
  • Can compensate sway bar pre-load from poorly manufactured sway bars (uneven arms)

Key features includes:

  • Heavy duty ball joints with Teflon® lining
  • Stainless Steel Spacers
  • Grade 10.9 Trailing Arm Bolts


One Pair of the NM Engineering Adjustable Rear Control Arms to allow Rear Camber correction.

Introducing the newly redesigned NM Engineering Control Arm kit. While others use 1" diameter 6061 aluminum material, NM machines our control arms utilizing aerospace grade 7075-T6 1 1/4" hex aluminum bars, finished with titanium tint Type III / Mil-Spec Anodize. The use of larger material provides rigidity and strength of steel bar but without the weight.

NM Control Arm Kit also features precision heavy duty rod ends made from heat treated hardened steel with self lubricating nylon race. The threaded rod ends allow user to dial the suspension camber to desired specs, crucial for the weekend track enthusiasts and professional racers. T-303 stainless steel is used for the spacers to avoid any flexing and crushing caused by suspension load.

Optional Rubber Rod End Boot Kit protects the rod ends against dirt and grime that may cause performance noise. Available separately
