From HB Racing:
This new Front Suspension B-Mount is a middle setting between the 1 dot and 3 dot mounts. It was developed based on feedback from our Team Drivers as a good all-around setup for the HB Buggy & Truggy 1:8 platforms. These B-Mounts allow racers to fine tune the front kick-up and roll center. The B-Mount controls the location of the rearmost end of the front suspension hinge pins. A higher B-Mount location makes the car smoother and easier to drive when the grip is high. They’re machined from aluminum, anodized black, and available in +0.0mm, +0.7mm, +1.4mm, and +2.8mm.
Compatible with: HB Buggy & Truggy 1:8 platforms
