rear bias plugs?

Todd TCE:
Pads work, so too do larger rotors, but the best value is larger piston area. There's more return on torque value with this, followed by pad Cf, then rotor diameter last. Sorry all you would be 14"ers...lol

I completely agree with all the previous cautionary posts on this.

This last statement leaves me a bit confused, though. While a larger piston generally does give better pressure distribution to the pad, it also requires more fluid displacement to get the same pressure, which should move the bias away from the caliper with the increased piston size (all else equal).

Did I misinterpret what you were saying, Todd? Did you mean putting a caliper with a larger piston on the rear, maybe?

ed. Okay - I think I need to start getting more sleep. I was thinking of a front-rear split system, where the increased fluid displacement required for the larger pistons would result in lower pressure on that circuit for a given pedal travel.

Since the SHO is diagonally split, the pressure is essentially equal front to rear (until the prop valve comes in, at least), so a larger piston in the front should move the balance to the front in this case.

Gary M.:

One time on a road trip a few years back, I inadvertently had too much rear bias dialed in, and encountered a panic stop situation on the highway. On I-70 through Glenwood Canyon in the Colorado Mountains, concrete barrier on both sides of the road, due to rear lockup, I ended up backwards facing oncoming traffic.

That would be enough to get my heartrate up! I can't think of a place along I-70 that would be pleasant to be the least bit out of control on.

Sorry, the statement had nothing to do with bias. It was a simple formula for increasing brake torque. At either end of the car. Or conversely; reducing it via the opposite. Remove the thought of valving for this.

Bias takes into account a lot of other factors as you understand.
