DESCRIPTIONBillet Performance Products solid diff ear mounts replace the factory rear differential ear mounts on Toyota JZZ30 and JZA80 applications with a rigid billet setup.They are aimed at higher-grip and higher-power cars where the factory rubber mounting allows too much movement, leading to wheel hop and a less direct feel under load. For workshop builds that see hard launches, sticky tyres or aggressive driving, solid mounts are a straightforward way to tighten the rear driveline.This is a functional driveline part rather than a comfort-focused upgrade, so it suits owners chasing response and durability over extra isolation.FEATURES MPN: BPP1008 Vehicle fitment: Toyota JZZ30 Soarer and JZA80 Supra Construction: Billet aluminium solid mounts Function: Helps eliminate wheel hop and diff movement Purpose: Improves rear driveline response and traction consistency Manufacture: Made in Australia TYPICAL APPLICATIONS Toyota driveline upgrades for high-power street cars Drag, drift and circuit rear-end preparation Tailshaft, diff and gearbox conversion builds Cars using sticky tyres or firmer suspension packages FITMENT NOTES Designed for Toyota JZZ30 and JZA80 rear differential setups Solid mounts will typically add more NVH than soft factory mounts Best suited to performance builds prioritising traction and driveline control Inspect diff bushes, subframe mounts and related driveline hardware during installation
