- Huge Spec Clubsport Package Example (£2,778) - Including Porsche Ceramic Composite Brakes (PCCB) (£5,597) & BOSE Sound System (£834) - Porsche Manufacturer's Warranty until November 2022 - UK Supplied The 718 Cayman GT4 had big boots to fill, following its late 2019 release, with the old GT4 receiving unfaltering praise due to the perfect combination of chassis and gearbox setup for track use. In light of this, Porsche have more or less kept the chassis the same, maintaining the impressive balance and stability it provides. Adaptations have been made to the previous design and incorporated into the new model to reduce air resistance around the re-designed body. These changes include a larger front splitter, with a wider bumper grille to increase airflow, a new larger single-piece rear wing that sits higher and a more aerodynamically efficient rear diffuser, which now channels air between the two separate exhaust tips. These revisions have resulted in a 40% increase in downforce on the rear axle over its predecessor. A dry sump has also replaced the old wet sump, meaning the engine can sit lower in the chassis, which in turn lowers the centre of gravity. Despite the heavily track-oriented design, the 718 GT4 by no means compromises on comfort for everyday activities. The standard damper settings allow for a firm suspension feel that is not too harsh, but still allows you to feel connected to the road through all 4 wheels. The new and refined features that Porsche have incorporated provides you with a car that builds your confidence on the track due to the precisely engineered handling and aerodynamics, whilst retaining the usual features found on a vehicle that can be used on a daily basis.
