Enkei - enk504-885-4535GM - GTC01RR 18x8.5 5x112 +35 Gunmetallic Wheel

Enkei GTC01RR wheels represent the pinnacle of track-focused engineering, combining ultra-high rigidity with extreme weight reduction for circuit racing and high-horsepower road applications. Built using Enkei’s advanced M.A.T. DURA process, this wheel utilizes a split six-spoke design that optimizes force distribution under extreme cornering loads while delivering crisp steering feedback.

• Tested to Enkei’s Spec-E quality standard, requiring higher impact drop energy and 20% more fatigue cycles than standard JWL requirements
• Dual valve stem architecture enables precise tire pressure monitoring while simultaneously purging ambient air during nitrogen fills
• Anti-slip bead surface treatment increases friction against the tire bead to prevent rim slippage under heavy torque loads
• Side-spoke pocket machining derived from Formula One engineering removes non-critical mass to minimize rotational inertia
• Deep rim barrel profile provides generous internal clearance for oversized multi-piston brake systems

The Enkei GTC01RR is a track-focused cast wheel engineered for circuit racing and high-horsepower road applications. Its split six-spoke design is intended to optimize force distribution under cornering loads while providing crisp steering feedback. This wheel features Enkei’s M.A.T. DURA manufacturing process and a gray gunmetallic finish.
