I stand corrected, $35 gets you the mid priced, but still brand name, rotor.
From the Advance Auto Parts site:
Raybestos 66442RGS
Disc Brake Rotor: Aimco-Gs; Front; Originally Equipped With Noise Dampening Iron; Rotor Only
3 Month Limited Warranty
Ships in 1 day
Weight: 15.6 lbs.
$32.99
They have 3 listings for rotors for a 94, all in the $35 range. They also have rotors as cheap as $21.88 and as high as $54.99(still cheaper then the $115 you paid for the pair).
If you go to the 96 rotor, they start at $24.94 and go up to $66.96(only about $20 more then what you paid for a pair). You pay the same and get a larger rotor. Now you just need to get the pads, which you probably were going to replace anyway, and mounting brackets. AZ, NAPA, Rockauto all probably have similar pricing.
You'd have spent ~$200 on brakes that will work better, won't warp as easily as the stock size, won't crack, and you have the best parts you can buy. Do you know what quality your rotors were originally? I'd bet they are probably one of the cheaper parts store "Made in China" ones...
