I had talked with Tobin at Kore3 several times about solving some of my brake issues. It seems that the master cylinder that I had was not a good fit for the front brakes that I wanted to upgrade to.
I have a 12" kit in the back and I wanted to upgrade the fronts to at least that size if not one size larger.
I have to say up front that Tobin knows his brakes and was very patient with all of my noobie questions.
We settled on a Wilwood master and adjustable prop valve along with a C6 brake kit.
I almost forgot about the hubs that also needed to be machined for the kit. Tobin had all of the measurements and drawings on line to help with the project.
It seems that I gave my drum brake hubs away a few years ago so I had to find some again. It ended up with me receiving two sets of hubs. I had that all machined down so I would have a extra set for who knows what.
Four crusty hubs.

The rotor face turned down.

Bearings and seals removed, and a sand blasting to clean them up.

New seals,races,bearings, and studs. They needed to be a little longer than the stock ones. Also put on a fresh coat of paint.

Drivers side all mounted up.
