Those are exactly what i have just put on the girlfriends car. I had a pair on my 2000 Eclipse GT for 5 years and not once did they crack or break or anything else. Maybe it's the pads you're using or something else causing it, but i've had zero issues with these on any cars i've put them on.
If i could i'd upgrade the girlfriends brakes to Brembo's like my STi. But her car is worth less than the brakes would cost, so not worth it.
You guys pay about 200 shipped, i get em for $100 dollars with a friend discount, but i dunno if he'd sell me more than 2 sets without knowing something is up, and i wouldn't defraud a friend like that. I can see about a group buy if there is interest?
