Race Kit Tubular Subframe

Just Engineering Race Kit Tubular Subframe - VW MK4 / Audi TT (PQ34)

The Just Engineering Race Kit is the ultimate bolt-on solution for drivers looking to transform the handling characteristics of their PQ34 platform vehicle. Designed to correct roll center and restore a functional bump steer curve on lowered vehicles, this kit provides professional-grade suspension geometry without the need for custom-fabricated knuckles. By optimizing the suspension arm plane, you reduce body roll and gain the ability to run softer spring rates for improved mechanical grip on the track.

This comprehensive package includes a high-rigidity tubular subframe, Stage 3 tubular control arms, and a specialized steering correction kit. Engineered over five years of development, this system cuts 25% of the weight compared to the stock unit while offering unparalleled adjustability in camber, caster, and track width. Whether you are building a dedicated time attack car or a high-performance street machine, Just Engineering delivers the precision and strength required for competitive driving.

Key Features

• Advanced Geometry Correction: Features multiple LCA mounting positions to correct roll center by 1" (25mm), allowing suspension arms to sit level or upward even on extremely low cars.
• Stage 3 Tubular Control Arms: 100% Chromoly construction with 4130N billet bearing cups and a double-pinch bolt design at the trailing arm junction for maximum strength and zero movement.
• Full Adjustability: Provides up to -3 degrees of camber and caster adjustment beyond chassis capacity, with the ability to extend track width by 5/8" per side.
• Integrated Steering Kit: Includes a unique bracket connecting the tie rod to the ball joint for added stiffness, utilizing rod ends to allow for precise bump steer tuning via supplied spacers.
• Weight Reduction: The tubular design provides a 25% weight saving over the OEM subframe while significantly increasing chassis rigidity.
• OEM Compatibility: Maintains the stock rack and pinion location to ensure original clearances for downpipes and surrounding engine bay components.

Fitment / Applications
