Verkline Fully Adjustable Wishbone Kit — BMW M2 F87 / M3 F80 / M4 F82 — Track Package — Stage 1
Complete kinematics & geometry correction system — 20 pieces — both axles
Key Features
- The only kit on the market covering both axles simultaneously, engineered in a single shared CAD model
- 20-piece complete system — all control arms, tie rod ends, drop links and inserts. Competitors average 8–10 parts
- Fully independent caster and camber adjustment — caster 6°–10°, camber 2°–5°, each without affecting the other
- Rear bump steer linearised — consistent, predictable toe change throughout full suspension travel at any camber value
- CNC-milled billet caster arm profile — tie rod collision eliminated by design
- FEA-validated across 28 load scenarios — same pre-production standard as professional motorsport
- EU-manufactured Getecno PTFE spherical bearings throughout — maintenance-free, no greasing required
- 42CrMo4+QT alloy steel, heat-treated to over 850 MPa yield strength
- Includes complete setup documentation for street and track — ready to hand to your alignment shop
The F8x Problem
The F8x M-chassis is one of the finest performance platforms ever built. But the factory geometry reflects road-car compromises that become real handling problems the moment you lower the car or take it to track.
-
Front camber — Fixed at −0.8°: Not adjustable without aftermarket arms. Far too little for track use — causes understeer and uneven outer tyre wear.
-
Rear camber vs. toe — One bolt, two axes: OEM eccentric bolts link rear camber and toe. Improving one compromises the other — you cannot optimise both simultaneously.
-
Anti-dive on lowered cars — Up to 60–70%: Lowering the F8x dramatically increases anti-dive — far beyond a Porsche GT3 (40%). Under braking it rises further, killing pedal feel and front-end feedback.
-
Rear bump steer — Non-linear & unpredictable: At track camber values (−2.5° or more) the OEM rear bump steer curve becomes non-linear. The rear axle actively steers itself under load.
The Solution
Every other manufacturer for the F8x sells either a front kit or a rear kit. Verkline is the only manufacturer to have engineered both axles simultaneously in a single shared CAD model — clearances, bearing axes and adjustment ranges are guaranteed compatible by design, not assumed.
-
CNC-milled billet caster arm: Not a straight rod. The milled profile routes around the tie rod — collision risk eliminated by design. Bearing housing angled at 4° to keep the spherical bearing within its articulation range across full suspension travel.
-
Fully independent adjustability: Caster 6°–10° and camber 2°–5° — each without affecting the other. Camber adjusted via the lower arm widens the track, reducing lateral load transfer — more grip from each tyre, not just more camber angle.
-
Rear bump steer linearised: Camber and bump steer are fully decoupled. The rear bump steer curve is linearised — consistent, predictable toe change throughout full suspension travel regardless of camber setting. No other F8x manufacturer addresses this.
-
FEA validation & material quality: Every component validated across 28 load scenarios — kerb strikes, combined cornering/braking G-forces, jump landing loads. 42CrMo4+QT steel (>850 MPa yield strength). EU-manufactured Getecno PTFE spherical bearings throughout — maintenance-free.

Fitment Notes
A full professional 4-wheel alignment is required after installation. The kit ships with complete setup documentation covering arm length presets, bump steer correction shim configurations and recommended alignment targets for both street and track — ready to hand directly to your alignment shop.
All Verkline arms adjust externally with wheels on the ground. Subsequent geometry changes between sessions do not require suspension disassembly — adjustable on a standard 4-post lift, garage floor, or directly in pit lane using the string method.
