these rotors will fit a 90-91 prelude definitely. probably will fit the 88-89, but i dunno. they are slotted and are for the front brakes. as in front left and front right. i had them on mine but i need the money. they are good rotors askin $75, have pics on comp,, but cant figure out how to get them online. i can email pics if u want to see them. tarheelsoldiercs@hotmail.com is my email address.
