A complete steering angle kit for BMW E9x and E8x models, designed specifically for drifting.

Compatibility

The kit fits the following BMW models:

• F80

• F82

• F87

Overview

The kit provides a maximum steering angle of up to 65°

To reduce the overall cost without compromising handling characteristics, the kit utilizes the factory BMW steering knuckles. Precision CNC-machined billet adapters are mounted to the original knuckles, converting them into a single-ball-joint design.

The result is a lightweight, durable, and easy-to-install steering angle kit, perfectly suited for both practice cars and professional drift competition vehicles.

The maximum achievable steering angle depends on wheel size, tire width, wheel offset (ET), suspension geometry, and steering lock limiter adjustment.

Key Features

• Maximum steering angle of up to 65°

• Geometry based on our proven F2x/F3x V2 kit

• Retains factory BMW steering knuckles

• Fully adjustable suspension geometry

• Adjustable Ackermann geometry

• Adjustable steering lock limiter

• No cutting or chassis modifications required

• Uses OEM BMW tie rods

• Extremely lightweight construction

• Designed and manufactured in Poland

Suspension Geometry Adjustment

Both the lower control arms and tension rods feature continuous length adjustment, allowing precise suspension setup.

Ackermann geometry is adjusted using interchangeable locking plates. The plates can be replaced quickly without removing the entire kit, making it easy to adapt the steering characteristics to different tracks and driving styles.

Adjustable Steering Lock Limiter

The kit is equipped with an adjustable steering lock limiter, allowing the steering range to be precisely matched to the wheel, tire and suspension setup.

The limiter allows you to:

• prevent tire contact with the fenders and bodywork,

• prevent wheel interference with control arms or other suspension components,

• reduce loads applied to the steering rack at maximum steering angle,

• protect tie rod ends, spherical bearings and steering components from excessive stress,

• fine-tune the maximum steering angle for individual vehicle configurations.

Billet CNC Steering Knuckle Adapters

The steering knuckle adapters are precision CNC-machined from PA4 aluminum alloy.

They convert the factory steering knuckle into a single-ball-joint design while maintaining correct suspension geometry and providing exceptional rigidity under extreme steering angles.

Upper Relocators (Camber Plates)

The kit includes a pair of upper camber plates allowing precise adjustment of the MacPherson strut position.

For proper operation, the suspension must be equipped with upper thrust bearings.

The spherical bearing (uniball) used in the camber plate is not designed to carry rotational loads. Rotating the suspension solely on the uniball would significantly increase steering resistance and accelerate wear of suspension components.

Compatible coilover brands equipped with thrust bearings include:

• YellowSpeed

• ISC Suspension

• BC Racing

• Lines Racing

• MaxpeedingRods

If your suspension does not include upper thrust bearings, suitable upper spring perches are also available in our offer.

Installation

Installation requires no cutting, welding or chassis modifications.

The kit uses the original BMW tie rods. Extended tie rod adapters with spherical bearings (uniballs) are included and are designed to work with our billet steering knuckle adapters.

Materials

Only high-quality structural materials are used throughout the kit.

Steering knuckle adapters

• CNC-machined PA4 aluminum alloy

Control arms and welded components

• S355 structural steel

Adjustment and threaded components

• C45 steel

• 42CrMo4 alloy steel

The combination of carefully selected materials provides excellent rigidity while keeping overall weight to a minimum.

Manufacturing

The entire kit is designed and manufactured in Poland.

All aluminum components are CNC-machined from solid billet material. We do not use cast components or materials of unknown origin.

Every component is manufactured from certified materials with known mechanical properties, ensuring excellent quality, repeatability and long-term durability. Replacement parts are available separately.

Spare Parts

All kit components are available individually as replacement parts.

Available spare parts include:

• Steering knuckle adapters

• Lower control arms

• Tension rods

• Tie rod extensions

• Ackermann adjustment plates

• Upper camber plates

• Adjustment hardware

The availability of replacement parts means that if a single component is damaged, there is no need to replace the entire kit. This helps reduce operating costs and allows the vehicle to be returned to service quickly.

Lightweight Construction

Thanks to the use of CNC-machined billet aluminum adapters and the original BMW steering knuckles, the complete kit weighs only approximately 13 kg including packaging.

Reducing unsprung mass improves suspension performance, steering response and overall vehicle handling.
