New from Factory Team are Vertical Ballstud Mounts for the RC10B74 series cars. These vertical ballstud mounts increase the tunability of the rear camber link, allowing for lower ballstud positions to be used as well as a further outward ballstud position. These pieces mount directly to the tower included in the RC10B74.1 kit. See below for details regarding mounting and setup capabilities.

The intent of these mounts is to allow drivers more versatility than what is available on the kit tower, particularly regarding mounting the inner rear ballstud, which affects the roll center and camber gain of the car. The extent of the available adjustment range will depend on multiple factors such as differential height, hub height, link length, and more.

The chart below shows the number of washers needed above the ballstud to match the vertical height of the positions available on the kit tower. N/A indicates positions that cannot be achieved with the Vertical Ballstud Mounts installed.

It is important to check that the camber links and ball cups are clear from interference with the outdrives, dog bones, and anti-roll bar before running the car with lower positions than the ones mentioned above.

We recommend the following items for adjustment with these Vertical Ballstud Mounts for positions lower than 2.5mm.
