I talked to the Cobb guy from Utah at the wicked big meet. From what I gather everything they package is researched and tested on that specific model its packaged for. So, it must be good.
sidenote; I asked about a Baja-t accessport. He said they'd gladly develope one if someone dropped off their Baja-t in Utah to use as a guinny pig for a couple weeks, but the long answer was no because there isn't enough Baja folks wanting or asking for the Baja AccessPort.
do you really necessitate an upgraded clutch? and as far as a lightweight flywheel goes, fidanza makes a good one which can be had for lots less @ places like http://www.boxer4racing.com
