This is DoctorDiff's kit. It uses Mustang Cobra calipers on a 10.7" Toyota rotor. It's 17 lbs lighter than 11" drums per side, for a total weight savings of 34 lbs.

The main benefits of this kit are:
1) All new parts. There is no scrounging or core charge involved.
2) Fits in stock 14" and 15" drop-center wheels.
3) Will work with stock tapered roller (set-7) bearings.
4) The price will be competitive with the TSM kit, and cheaper than everything else.
5) Easy/Clean install.

He's also coming out with a larger 11.7" version that will fit in some but not all 15" wheels.

Cass didn't bring this kit to the Nats, as it is being shipped to a customer, but you can talk to him there. Otherwise, he will be back around August 22nd. It should be for sale by the end of August.
