The CRT bushings were developed for use in modified vehicles as well as for clubsport and motorsport applications.\u003c\/p\u003e\n\u003cp\u003eThe bearing design is based on the solution that was very successfully used by BMW Motorsport in the \u003cstrong\u003eWTCC \u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe focus is on \u003cstrong\u003eweight savings compared to the standard bushings and the targeted adjustment of the roll center height on the rear axle.\u003c\/strong\u003e Especially on lowered vehicles, the suspension geometry and thus the position of the roll center can change. The corresponding roll center correction allows for a targeted adjustment of the rear axle geometry to the respective vehicle and suspension setup.\u003c\/p\u003e\n\u003cp\u003eThe rigid aluminum construction massively reduces the elastic deformation of the bearing compared to standard rubber bearings. This allows the rear axle to be guided more precisely, creating a more direct driving feel and more consistently reproducible vehicle response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLightweight construction: Weight reduction compared to the standard bearing:\n\u003cul\u003e\n\u003cli\u003e0.95 kg lighter than the OEM bushings\u003c\/li\u003e\n\u003cli\u003eadditional 1 kg savings by eliminating the aluminum strut bar (non-M E46)\u003c\/li\u003e\n\u003cli\u003eadditional 4.5 kg savings by eliminating the steel strut bar with V-brace (M3)\u003cbr\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEliminating the factory rubber bushings also removes the need for the support provided by the original thrust brace, making the brace redundant.
