It is specifically designed for motorsport-style wing installations that use the BMW GTS-style mounting configuration.\u003c\/p\u003e\n\u003cp\u003eLarge rear wings can transfer substantial aerodynamic and mechanical loads into the trunk panel during high-speed driving, track use, and repeated loading cycles. Without proper reinforcement, these concentrated forces may place excessive stress on the outer and inner trunk skins, potentially causing movement, deformation, cracking, or damage around the mounting holes.\u003c\/p\u003e\n\u003cp\u003eThe reinforcement sleeves create a rigid connection between the upper and lower trunk structures, helping distribute wing loads through a stronger and more stable mounting point. This provides improved support for the wing uprights while reducing localized stress on the trunk panel.\u003c\/p\u003e\n\u003cp\u003eEach kit includes four precision-machined M6 reinforcement sleeves designed to be installed directly into the trunk lid at the rear wing mounting locations.\u003c\/p\u003e\n\u003ch3\u003eCompatible RM Engineering Wing Systems\u003c\/h3\u003e\n\u003cp\u003eDesigned for use with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRM Engineering GT4 MK2 Rear Wing\u003c\/li\u003e\n\u003cli\u003eRM Engineering Ring Spec Rear Wing\u003c\/li\u003e\n\u003cli\u003eRM Engineering M235iR Rear Wing\u003c\/li\u003e\n\u003cli\u003eRM Engineering M240iR Rear Wing\u003c\/li\u003e\n\u003cli\u003eOther compatible BMW GTS-style wing mounting configurations\u003c\/li\u003e\n\u003cli\u003eCompatibility may vary depending on the wing mount, trunk lid, and installation configuration.
