MASSIVE GRIP UPGRADE for PORSCHE 718 GT4 and GT4RS PART 2

We take our Porsche 718 GT4 to Donington Parck Circuit to see how the car now performs with much bigger tyres. We developed a new rear top mount that allowed much bigger wheels to be fitted on the rear. Upgrading the stock 295 rear to a massive 325!! The rear top mount allowing this fitment without any Bodywork modifications, a world first for both the GT4 and GT4RS For more info about these upgrades including what wheel size head to https://shop.suspensionsecrets.co.uk/...
