Why Convert Your McLaren 570S to a Longtail? The McLaren 570S is the most accessible supercar in the McLaren lineup — and the most popular platform for owners who want track-level aggression without selling a kidney for a 600LT. The longtail design language represents everything McLaren does best: lower drag, higher downforce, and a visual stance that separates your car from every other Sport Series on the road. The YPG Longtail Aero Kit is a complete bolt-on carbon fiber body conversion that transforms any 570S, 570GT, or 540C into a longtail-inspired machine — with a performance exhaust included in the...

The AMG GT platform demands heads that can flow under sustained high-RPM, high-boost, high-heat conditions — lap after lap. Our M178 CNC-ported heads are flow-bench developed for the dry-sump 4.0L V8, assembled with upgraded valvetrain, and sold as a matched pair. Built at YPG Motorsport in Kuwait, shipped worldwide. What Are CNC-Ported Heads? CNC porting reshapes the intake and exhaust ports using computer-controlled machining to our flow-bench program. Every port is cut to identical runner volumes and matched flow rates across all eight cylinders. On a twin-turbo engine like the M178, ported heads reduce pumping losses, improve turbo spool, and...
