It removes the deflection that allows rear toe to move under load, which is what makes a powerful rear-drive chassis feel unsettled on corner exit.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhere Rear Toe Movement Comes From\u003c\/h3\u003e\n\u003cp\u003eThe traction arm takes the longitudinal load of acceleration and braking, and its rubber bush deflects under both. On a car making S55 or S58 power that deflection is significant, and it changes rear toe exactly when the driver is asking the rear axle for grip. The sensation is a rear end that moves around under power in a way that does not correlate with throttle input.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eConsistent Geometry Under Power\u003c\/h3\u003e\n\u003cp\u003eFitting a machined pillow bush removes the compliance and holds the toe setting regardless of load. Corner exit becomes predictable, the throttle can be opened earlier with confidence, and rear tyre wear evens out because the contact patch is no longer being dragged through a changing angle.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eA Direct Bush Replacement\u003c\/h3\u003e\n\u003cp\u003eThe bearing is a direct OEM-fit replacement for the factory bush and works with the standard arm, so there is no need to buy complete replacement arms. It suits road and track use, and pairs naturally with the MMX rear camber arm bearing for a complete rear axle solution.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMachined 6061-T6 aluminium pillow bush design\u003c\/li\u003e\n\u003cli\u003eEliminates the deflection of the OEM rubber bush\u003c\/li\u003e\n\u003cli\u003eHolds rear toe consistent under acceleration and braking\u003c\/li\u003e\n\u003cli\u003eMore predictable corner exit on high-torque applications\u003c\/li\u003e\n\u003cli\u003eReduces uneven rear tyre wear\u003c\/li\u003e\n\u003cli\u003eDirect OEM-fit into the standard arm\u003c\/li\u003e\n\u003cli\u003eSupplied as a pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e MMR55-1650\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pillow bush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As:\u003c\/strong\u003e Pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW G80 M3, G81 M3 Touring, G82\/G83 M4 and G87 M2\u003c\/li\u003e\n\u003cli\u003eBMW F80 M3, F82\/F83 M4 and F87 M2 including Competition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eShould these be fitted with the camber arm bearings?\u003c\/strong\u003e\u003cbr\u003eThey work well together.
