ok... well i still want to know the size of the 93 integra rear discs for self satisfaction...i do understand what you mean and i was thinking about and your right i think i will keep the stock rotor and brake pads for a while since its not like im going to try to stop a prelude engine or soemthing, but like said i would like to know what size those rotors are just to know the size of my brakes, also i nthe front i said i had 90 civic si front brakes i would like to know that size as well because i am going to have a chance to take out the integra spindle as well and if those have bigger brakes ill take those that way i dont need to do any big brake conversions that cost me alot of money in the future, other brake components that im using are the inegra booster and master cylinder, i think that after those things i will not have a problem at all try to stopp that crx even with that Ls motor in it. so if you know these sizes please let me know thanks
