The same is nearly true for Stoptech, however. They don't have a rear kit to match the front 332. The 332 kit is designed as a front only kit to be used only with a stock rear setup. There are a few racing series that allow a front upgrade but not a rear and this kit is perfect for that.
As for configuring it to work on the rear, the first problem would be the correct caliper mounting bracket. Since they don't sell a 332 rear kit, they wouldn't have a bracket. I've looked into a similar situation in the past and the way Stoptech breaks up the parts, you would spend almost as much as buying a brand-new kit. Even piston sizes are different.
