When to replace Stoptech rotors

I feel I was faster on OEM brakes.

Then don't use the brakes as much and you won't slow down...

The Miataheads I have been hanging around with are considering removing the brakes to save weight.

How about the type of pads being used. Jack's preference is either the Cobalt or PFC. Does not like the Hawk pads we have tried. Our rotors have either been the the stock one that were on the car when we bought it or generic NAPA ones put on prior to Road Atlanta. We haven't experienced the glazing problem Dennis has described.

I question your engineer degree.........
I still have an increase in rotational mass.

Going from 12" to 13", yes, but the total increase of inertia on the rotor/wheel/tire combination is minimal.

In fact, the increased inertia will allow you to carry more speed without your aero drag slowing you down...
