I've had the car from new and ever since I had it the front brake rotors have needed skimming every 5,000 to 8,000 miles. Of course, this also means the rotors need replacing after each 2nd or 3rd skimming.

Happens on both front wheels, and, as likely expected, never the back ones

I have always used stock rotors and stock brake pads

The car is a very early '93 model

I don't do track driving. However, I do drive fairly hard, but I have several buddies with the same car and same driving habits that have no rotor warping problems. Of course, even when the car was in warranty, I got no sense from the dealer - they just changed 'em out (for free). However, now it’s my nickel, to say nothing of the inconvenience.

The only difference seems to be that my buddies’ cars are a '94 year or beyond. So I'm wondering, does anybody know of a change to the rotor, (thickness, for example), that Mazda may have made early in the gen3's life? Anyone else have this problem? Anyone solved it? Do aftermarket rotors do a better job in this respect? Are the rotors the same part for all gen3 model years?

Many questions, but the bottom line is that I want to fix it without making any major mod to the car. I'm coming up to a re-skim, (or more likely this time it will be a rotor replacement due to skim-down-caused “rotor-too-thin” syndrome. Any advice would be much appreciated.
