Front brake discs at 1.4 mil,should i change?

[thstone]

I have driven my Boxster on solid, cross drilled, and slotted rotors. On the street, I don't notice any difference in braking performance or feel in regards to rotor type. They all work fine, cool fine, and have pretty much the same feel to me.

On the track, drilled rotors cool better and therefore have better feel when really hot, but they also crack and need replacement earlier than solid or slotted. Solid and slotted felt the same to me on the track.

The pad will make much more difference than the rotor because each pad will have somewhat different characteristics of initial bite, stopping power, and heat resiliency.
