Gem Forged C8G 20x8.5 / 20x11 wheels for Porsche Cayman
Gem Motorsports GEM C8G Forged Wheels Porsche Cayman The GEM C8G brings its signature Y-split spoke design to the Porsche Cayman — a mid-engine platform that deserves a wheel with genuine visual intensity. The Y-split spoke architecture flows from the hub outward with each branch sharply angled near the rim, creating a layered, high-detail face that complements the clean, precise character of the Cayman body perfectly. Deep concavity, premium finish options including Chrome Gold, and a fitment engineered specifically for the Cayman arch give the C8G everything this platform has been asking for. Crafted from precision-forged 6061-T6 aerospace-grade aluminum, the C8G is stronger and lighter than any cast or flow-forged alternative, engineered to the 5x130 bolt pattern of the Porsche Cayman with no modifications required.

Each wheel is handcrafted, hand-powder coated, and undergoes quality control to meet U.S. customer standards. Due to the nature of the manufacturing and finishing process, minor imperfections such as microscopic blemishes under the clear coat may occur and are considered normal in the aftermarket wheel industry. These do not affect performance or appearance from a standard viewing distance.

By purchasing our products, you acknowledge and accept these terms. All wheels are still covered under the manufacturer's powder coat and structural warranty. Cancellation Policy All wheels are custom built to order. Cancellations requested within 7 days of purchase may be eligible for cancellation, depending on production status. However, after 7 days, all forged wheel orders are considered final and cannot be canceled under any circumstances.
