C6 Corvette Rearend - More Grip, Less Slip

A pro-quality differential demands a suitably stout housing, so we decided to yank the '05's famously frangible factory rear in favor of a heavier-duty piece from a C6 Z06. Fortunately, RPM Transmissions makes a conversion kit to facilitate this swap, complete with a media-blasted case, fresh seals, and micropolished gears in a choice of ratios. Although RPM typically loads these rears with factory Z06 internals, the company agreed to outfit ours with the OS Giken Super Lock hardware instead.

Next, to address the brake-fade issue, we pulled the 5-year-old factory pads and installed Hawk PC (Performance Ceramic) pads in their place. The PCs use one of Hawk's less aggressive compounds, making them suitable for street driving as well as occasional track use.

And finally, since all the braking and driveline upgrades in the world are meaningless without adequate rubber, we had a local tire shop strip off the car's old mud-and-snow Michelins and replace them with a stock-size set of Nitto's excellent Invo performance radials.

So, did our curative ministrations have the desired effect on the C6's track performance? We'll get to that soon enough, but first, let's take a closer look at the parts we used in the project and some of the work involved in installing them.
