Rear Steel Subframe and Suspension Linkage Surface Salt Corrosion
MinorSuspension & ChassisBecause the GT86 sits low to the ground and features minimal factory cavity wax on underbody suspension components, exposure to salted winter roads in the UK causes heavy surface rust and oxidation across the rear steel subframe, toe arms, anti-roll bar brackets, and rear brake dust shields. Left untreated, rusted fasteners seize firmly into suspension bushes, inflating labour costs for routine wheel alignment.
Flaking rust and heavy orange scaling visible across rear suspension arms and subframe welds, Creaking or squeaking noises from rear suspension over speed humps in dry weather, MOT advisory noted for suspension component mounting obviously rusted
- Inspect the rear subframe, exhaust backbox, and differential casing with a torch for deep rust scale
- Check if previous owners had anti-corrosion underseal or Lanoguard protection applied
