What I did was a definite upgrade. People say the 1LE brakes are also better than stock, the C4 brakes are the more common but slightly different than the 1LEs, still basically the same. There are also people who run the stock iron brakes at the track and have no issues. Don't know how they pull it off but I bet they may be running DOT 5 fluid (or is it 4, i may be flipping one or the other) raising the braking fluid boiling point.
Here is the detailed explanation with all the math BS.
"The braking torque or "power" as you call is the (braking force) * (radius from center of the spindle to roughly the center of the pad). Braking force is determined by the hydraulic advantage in the system. Force = (piston area) * (fluid pressure). Fluid pressure remains the same when swapping brakes, so really only the piston area matters.
Stock
piston area: 4.43 sq in
effective radius: ~9.5"
Torque = P * 4.43 * 9.5 = 42.1 * P (P is brake fluid pressure)
LS1
piston area: 4.81 sq in
effective radius: ~11"
Torque = P * 4.81 * 11 = 52.9 * P
So the LS1 setup has about 25% more braking torque than stock at the cost of ~9% longer pedal travel to generate the same fluid pressure. Not a bad trade off for a setup that has to fit in a 16" wheel." TGO member.

Just curious, the effective radius of what in the braking system is 11"?
