IND | Fall Line Motorsports F8X M3/M4 Rear Upper Control Arm Bearing Kit
Standard rubber bushings found in the F8X M3/M4’s rear upper control arms are the last weak link in an otherwise rigid suspension. The original BMW bushings yield to cornering forces applied to the suspension, resulting in camber and toe change that is not ideal for performance driving. The Fall Line Motorsports kit replaces the soft upper control arm bushings with military spec spherical bearings, enabling the rear suspension arms to move smoothly through their travel and giving the rear of the car a more solid, planted feel. The reduced geometry change allows for the vehicle to retain its desired alignment, maintaining better control and predictability of the tires under heavy load. The Fall Line Motorsport F8X M3/M4 Rear Upper Control Arm Bearing Kit is available with the bearings pre-installed into a new OEM set of control arms, or as the bearings alone. The Fall Line Motorsports F8X M3/M4 Rear Upper Control Arm Bearing Kit may be viewed here in our online store: https://ind-distribution.com/product?sku=FLM-F8X-1BRUCA Please contact IND by phone or email for more information or to place your order. 866.963.4520 | info@ind-distribution.com Fall-Line Motorsports is a premiere builder and fabricator of racecars for all levels of competition.

How's noise / vibe after these?
I'm always trying to walk the line between the fact that I daily drive my M4 but enjoy a track day whenever I can make it happen |

There's only a very slight increase in NVH. I barely notice it, but everyone has different tolerances for these things.
