rotor life
My 1988 turbo rotors have the following thickness:
Front: 26.30 mm
Rear: 22.75 mm
Clarks-garage says minimum are:
Front: 26.00 mm
Rear: 22.00 mm
How much normal driving miles can I get out of them? What happens if I go under the minimum thickness?
Front: 26.30 mm

IMHO get the rotors as soon as possible, after all they do stop the car.

You're still above the minimums so it is probably fine to drive your car as is, but when you do hit those minimum values I would replace ASAP. May even want to order new rotors now so you have them available when it's time to replace the rotors.
But that's just my very uninformed opinion and I'm sure many here with more experience will disagree...

Almost exactly one year (and 17,000 miles) ago I replaced my rotors because they were a bit warped and they were at their thickness limit. About six months ago I started noticing a lot of vibration during braking, and last week I had the rotors resurfaced. The shop said they had to take them down close to the minimum thickness. Granted, I did one day of a PCA-sponsored "high performance driving clinic" back in November, and there was a lot of hard braking. Should I expect one track session to kill a set of rotors?
I purchased the rotors from Vertex. They are supposedly OEM. Should I buy different rotors in the future? Should I go with cross-drilled or slotted?
Also, I noticed there is what looks like a dust shield inboard of each rotor. Would removing these allow the brakes to stay cooler?
