2019 Porsche 718 Cayman GT4 Clubsport

A track-dedicated race car derived from the road-going 718 Cayman GT4, the GT4 Clubsport pairs a 3.8-liter flat-six with a 6-speed PDK dual-clutch transaxle and a mechanical differential lock. Built to a full factory competition specification, it comes equipped with an integrated roll cage, a fire suppression system, a 115-liter fuel cell, an air jack system, three-way adjustable dampers, 18" forged wheels, a Recaro racing seat, and a Cosworth LCD driver display. This 2019 example was campaigned by ACI Motorsports in endurance racing before passing to the current owner for track-day use in the Pacific Northwest. Showing approximately 24k miles, this GT4 Clubsport is now being offered for auction in Illinois. Finished in white and wrapped in a blue and black livery, the GT4 Clubsport features yellow-tinted headlamps and silver 18" forged wheels. Its bodywork includes an aluminum composite bodyshell, lightweight natural-fiber composite doors, a plastic windshield, a roof escape hatch, side air intakes, tow straps, hood pins, a fixed swan-neck-mounted rear wing, and dual center-mounted exhaust tips. The seller notes that the hood was not pinned during a recent track outing and flew up against the windshield, and a replacement hood in like-new condition is included in the sale. Detailed images are provided in the gallery. The stripped racing cockpit features a fully welded roll cage, a Recaro racing bucket seat with a Schroth harness, and a 911 GT3 R carbon fiber steering wheel on a quick-release hub. Additional equipment includes a carbon fiber switch panel, carbon fiber door panels, a fire suppression system, a brake bias adjuster, an air jack system, a lithium-ion battery mounted in the passenger footwell, automatic climate control, and a Cosworth LCD digital display with an integrated data logger. The GT4 Clubsport uses a 3.8-liter version of the road GT4's flat-six, producing up to 425 HP, with drive to the rear wheels through a 6-speed PDK dual-clutch transaxle and a mechanical differential lock. Competition hardware includes a 115-liter fuel cell, variable-ratio power steering, three-way adjustable dampers, adjustable ABS, bias-adjustable twin master cylinders, and slotted multi-piece rotors with 6-piston front and 4-piston rear monobloc calipers. The seller reports recent maintenance including new drive shafts, a PDK service with a new clutch pack and anti-rotation blocks, new rear suspension uprights, and new fuel pumps in 2026. A recent leak-down test returned healthy figures of 7 to 10 percent across all six cylinders. This sale will include a bill of sale, a replacement hood, two sets of wheels, an air jack wand, several sets of brake pads, and a set of rotors. The seller would like you to know: "This car was run by ACI Motorsports and then sold to the current owner for track-day use in the Pacific Northwest. It has been very well cared for and maintained, with new drive shafts, a PDK service including a new clutch pack and anti-rotation blocks, new rear suspension uprights, and all-new fuel pumps in 2026. A recent compression check and leak-down test read very healthy across all cylinders. The car has more miles than average, but everything checks out great."
