Unlike some other wheels on the market, Classic centers cannot be changed from standard (face) mount, to front register (reverse) mount. The machining process between the two parts is noticeable different.

One of the major differences between our “Race” version, and “Street” version wheels, is in the hardware they are assembled with.

Race version wheels are machined for, and built with 6-pt cadmium plated Grade 8 hardware. Where Street version wheels are machined for, and assembled with 12-pt stainless ARP hardware.

The two are NOT interchangeable, as the depth and diameter of the bolt holes are not consistent between race and street version parts.
