McPappy Racing Caster Blocks & Bumpstops

McPappy Racing has now released a number of new items for their Dart 1/10th scale oval racer. First up is a line of 0, 5 and 10 degree Caster Blocks, which feature 3 holes for the upper wishbone mount that allow you to choose how much camber gain you want ,while providing 0, 5 or 10 degrees of active caster. To compliment the new blocks are these precision machined, adjustable bumpstops that allow you to independently control exactly how far each front wheel suspension will travel. You can engage them just a little bit to keep your chassis from bottoming out, or you can engage them earlier to control how the car reacts in the corner. One of the biggest benefits of running bumpstops is getting more weight on the left front wheel in the corners. As the car enters the corner weight shifts diagonally to the RF wheel. The RF bumpstop engages and now the weight travels to the LF wheel. Then the LF bumpstop engages and applies weight down on the left wheel. Bumpstops also can prevent rolling and keep the car level in the corners. These bumpstops are slotted so that you can slide them forward or rearward depending on how much caster you are running.
