Bassett 37ST4L Details

The 13" Bassett Inertia Advantage series wheels use the Inertia Advantage five-spoke center design and a high quality spun-form shell
The brake cooling holes feature almost 9 square inches more area, while the weight placement in the center helps the wheel rotate faster
CNC spun form rim shell construction and strict quality control means runout is much lower than other 13" wheels on the market
Light weight and low runout (under .030") thanks to spun-form wheel shells produced in-house
Reinforced torque ring and forged coining on center increases durability
The 5/8" valve stem hole is located behind the center to avoid clipping
Larger brake cooling holes reduce brake temperature and prevent fading during long feature races
PLEASE NOTE: Bassett Racing Wheels are lug-centric, which means the wheel is constructed and trued off of the bolt circle
The center hub bore hole can not be used to balance Bassett Racing Wheels
We recommend using an experienced tire mounter with a bolt pattern adapter plate that allows for balancing off of the bolt circle
Bassett Racing Wheels also require 45 degree chamfer lug nuts
