Looks interesting for those guys that race all the time wonder how loud the gear box it will be.
From their web site:
We at PPG are proud to announce that Keisler Engineering is now the USA stocking distributor and official assembler of the new HEAVY DUTY Road and Track 6speed gearset. Developed by both PPG and Keisler, the set is a bulletproof replacement for the standard T56 transmission found in Challengers, Corvettes, Camaros, Vipers and Mustangs.
