It also improves the centering torque on the steering wheel for straight line stability and additional tire feedback. The result is better grip mid-corner and an improvement to peak braking by slightly reducing the need for static camber.\u003c\/p\u003e\n\u003cp\u003eAdjustable caster also allows you to adjust the wheel location (side view) to prevent tire rub with the front bumper, or fender in some cases.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEliminates Bushing Deflection\u003c\/strong\u003e\u003cbr\u003eNo More Sloppy Steering and Squishy Brakes\u003c\/p\u003e\n\u003cp\u003eThe OEM caster rod bushing is a huge, hydraulic bushing that prioritizes comfort at the expense of performance. Under braking, steering, or acceleration load the bushing will deflect significantly, leading to a rubbery steering and braking feel and an unwanted change in bumpsteer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReduces Wheel Hop\u003c\/strong\u003e\u003cbr\u003eAvoids Hammering the Drivetrain\u003c\/p\u003e\n\u003cp\u003eOn xDrive models, a hard launch on grippy tires results in the front wheels suddenly loading the caster rod. This results in caster rod bushing deflection which allows the unsprung mass (wheel, tire, etc) to lurch forward. This movement generates inertia (energy) that is poorly dampened, resulting in a rebound force that feeds into the tire and can initiate wheel hop or tire spin.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEliminates Bushing Bind\u003c\/strong\u003e\u003cbr\u003eLess Bind, More Control\u003c\/p\u003e\n\u003cp\u003eLoad transfer under acceleration, braking, or cornering results in the rotation of the caster rod bushing. The OEM bushing generates significant amounts of bushing bind, limiting the droop travel, and acting as a rubber spring, actively resisting suspension movements and releasing that stored energy. Upgrading to a spherical bushing eliminates this bushing bind, and allows the suspension to properly articulate without generating additional unwanted forces.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNoise, Vibration, and Harshness (NVH)\u003c\/strong\u003e\u003cbr\u003eProduct NVH Rating\u003cbr\u003eThe caster arm bushings are an active part of NVH control strategy for the front suspension. The trade-off for performance is additional NVH over rough roads, particularly hard bumps, a small increase in road \/ tire noise, and a greater likelihood of tramlining for some setups. However, the ride quality on smoother roads, even with some rolling bumps, will be improved over stock due to the elimination of bushing bind. Going to a high-quality coilover with suitable spring rates will further enhance this improvement and mitigate some of the NVH impact.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReplaces OEM Part Number(s)\u003c\/strong\u003e\u003cbr\u003eThis is a list of known OEM part numbers.
