What do you think of my set up

[oasis]

Excessive is a value judgment. I never found having rear disc brakes excessive. I had TopLine front and rear brakes. If my next project parallels my first, I will probably upgrade the front brakes further and do something very similar for the rears.

One way to straddle the decision is go with Type 3 rear drums. I have no experience whatsoever with the set-up, but the consensus I have heard is the Type 3 drums are an upgrade over stock Type 1 drums.
