Verkline BMW M2/M3/M4 F8X Fully Adjustable Wishbone Kit – Stage 1 Track Package

Verkline Fully Adjustable Wishbone Kit – BMW F8X M2, M3 & M4 (Stage 1 Track Package)

The Verkline Stage 1 Track Package is a complete suspension geometry solution for the BMW F87 M2, F80 M3 and F82 M4. Unlike most competitors who offer only a front or rear kit, Verkline have engineered both axles together in a single CAD model, meaning every arm, link and bearing is designed to work as one cohesive system.

This 20-piece kit corrects the factory geometry compromises that become apparent once the car is lowered or driven on track. It gives you full control over caster, camber, toe and bump steer, with all adjustments made externally – no need to disassemble the suspension between sessions.

Why the F8X Needs This Kit

The F8X M-chassis is an excellent platform, but its factory geometry was set up for road-car comfort. Once you lower the car or push it on track, two main issues appear:

• Rear bump steer: At factory camber settings beyond -2.5°, the rear toe curve becomes non-linear. In simple terms, the rear axle starts to steer itself under load, making the car feel unpredictable mid-corner.
• Limited front adjustment: Caster and camber on the OEM arms are interlinked, so changing one affects the other. Wide wheels also risk contact with the inner arch at full steering lock.

Verkline addresses both problems directly. The rear bump steer curves are linearised at any camber value (0, 2 and 4 deg/m), giving consistent and predictable behaviour throughout the full range of suspension travel. At the front, caster (6° to 10°) and camber (2° to 5°) adjust fully independently of each other.

Engineering and Materials

Every component is built to withstand the demands of track use:

• CNC-milled billet caster arms – the curved design eliminates tie-rod collision by geometry, not by instruction
• 42CrMo4+QT alloy steel, heat-treated to over 850 MPa yield strength
• EU-manufactured Getecno PTFE spherical bearings throughout – maintenance-free
• FEA-validated across 28 load scenarios including kerb strikes, combined cornering and braking loads, and jump landing forces

What’s Included – 20 Pieces

Front Axle

• 2x Adjustable Caster Arms (WAS-450) – ±22 mm
• 2x Adjustable Camber Arms (WAS-451) – ±25.5 mm
• 2x Adjustable Tie Rod Ends (WAS-452) – bump steer corrected via shim stack
• 2x Adjustable Front ARB Drop Links (WAS-453)
• 4x Steering Rack Limiters – prevents tyre-to-arch contact at full lock with wide wheels
• 1x Ride Height Sensor Bracket – retains OEM headlight levelling sensor (left side)

Rear Axle

• 4x Rear Upper Arm Inserts – spherical bearing replacement, retains OEM forged arm
• 2x Adjustable Lower Trailing Arms – full camber and bump steer adjustment
• 2x Adjustable Toe Links – extended range
• 2x Rear Subframe Inserts
• 2x Adjustable Rear ARB Drop Links

Adjustment and Setup

All Verkline arms adjust externally with the wheels on the ground. Once installed, you can change geometry between sessions on a standard lift, garage floor, or directly in pit lane using the string method – without disassembling anything.

Every kit ships with complete setup documentation, including arm length presets, bump steer correction shim configurations, and recommended alignment targets for both street and track use. Hand the document to your alignment technician and the car will be correctly configured from the first session.
