Bassett Inertia IMCA Certified 3 Tab 15x8 Wheel, 5x5 BP
15 Inch Wheel Diameter, Steel, 8" Width, 5x5 in. Wheel Bolt Pattern (in.), Powder Coated
The 15" 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 more area, while the weight placement in the center helps the wheel rotate faster. Also, CNC spun form rim shell construction and strict quality control means runout is much lower than other 15" wheels on the market.
- Patented 5-spoke center provides low moment of inertia and more horsepower to the track
- Spun-form rim shell equals higher steel yield strength and lower runout
- Lightest weight allowed by IMCA
- Available in black or silver powder coat
- Choose three available backspacing 2, 3, and 4 Inch
The term "inertia" refers to the tendency of an object in motion to stay in motion unless some force acts upon the object and makes it behave in a different way.
The inertia of a wheel rotating on a circle track race car undergoes four acts of force each lap. Using a proprietary, in-house testing apparatus, Bassett discovered that a wheel designed with more of its weight in the center required less force to rotate.
But it wasn't as easy as simply making the center material thicker. That would raise the overall wheel weight, which was unacceptable.
So Bassett's engineers conceived the unique five and six-spoke center designs, which place more weight in the center without raising weight or affecting strength.
Many racing products claim to be "bolt-on" horsepower, but Bassett Racing Wheel's Inertia Advantage center designs are proven to be faster. You can see the difference yourself by using a chassis dyno to measure rear wheel horsepower.

For offroad use only. The following must be considered when using Bassett wheels for on highway/street use when the wheel/tire assembly is being balanced. Bassett wheels are lug centric, which means they are built off of, and must be balanced using, the bolt circle and NOT the wheel center hole. Improper use of a tire balancer that centers the wheel on the hub bore, not the bolt circle, will result in an incorrect reading for rim runout as the center hole is not in the perfect center of the bolt pattern. The only machine capable of performing a lug centric balance is the Hunter GSP 9700 with the flange plate bolt circle adapter and no centering cone.
