and the tranny consists of a stock flywheel, Cusco cerametallic clutch, and some internal modifacations done in house. its held up to heavy abuse at the track, including numerous 40 or more 1.6-1.7 60ft times. i dont care what anyone says about the stock trannys, they are good to 300 at the wheels, IF driven correctly. although i dont expect it to last too long w/ this set up
