A pair of Billet Specialties COMP7 rear wheels in 1/24 scale.

Includes:

• Deep Outer Rims
• Inner and Outer Center Inserts
• Instructions 

Wheel dimensions:
Width .730"
Outside Diameter .730"

Note the difference between the 1/24 version (left) and the 1/25 version (right) below. The 1/24 rear wheels have a 'lip' or 'rim' at the front and rear edges. Some slicks have a more pronounced rounded sidewall and this lip will help fill in space. A flatter sidewall won't need this and the lip may even protrude a little.

Left wheel below had the optional bead lock ring and back half of the wheel center painted black (before polishing the center). 

The right example shows an unpainted optional beadlock ring, the outer wheel center is polished, and the back section is unpolished.

Matching front wheels are also available (photo of real world wheel)
