well... i have 4 rotors on my prelude si that are cross drilled and slotted. Im currently parting the car out but i want to keep my rotors for the next car im going to get. now the question is if anyone knows if these rotors from the prelude si will fit an integra or civic. i know they have the same bolt pattern so the rotor will go on and i have 17'' rims so i know the rotors wont hit anything but will i need to use the same prelude si calipers or can i use the integra or civic calipers (if i get a civic or integra) if someone or if you know someone who has done a prelude to civic or integra rotor swap pls let me know. thanks.

 

No. They do not have the same bolt pattern. Ask me how I know.

 

You could have them redrilled, but I strongly recommend you get some blank rotors from brembo or honda. Cross drilled and slotted rotors offer less performance, more cost, and if they're made by someone other than brembo they're probably likely to crack over time.

Drilled rotors also shorten pad life. Do they really look that cool? They sure cost a lot for a performance decrease.

 

hmm i thought the bolt pattern was the same... lol nvm. but i dont think these rotors "decreased performance" if anything these rotors really woke up my braking, sure the pads dont last as long but thats only because its obviously on a cross drilled and slotted rotor!!! :D anyways thx for the help guys.

 

You'll increase initial bite, but initial bite means nothing. Cross drilled/slotted rotors have less mass, therefore heat up more quickly.

These cars are tiny, eliminating brake fade should be the braking modification mentality, not bite.

Preludes, by the way, are 4x114, and civics/integras are 4x100.

If it "woke up" your braking it's all in your head. There is less metal there than a regular rotor. Meaning less mass, and quicker brake fade. Your rotors get hotter quicker than blank rotors.

Not to mention better initial bite isn't necessarily a good thing if you're trying to do any performance racing like autocross. Having less touchy brakes that are strong when you need them is a good thing. Too much bite can cost you seconds on a lap.

If you're daily driving it, you're just doing it to look cool. Which is fine, just know the above. Anyone who knows anything will know you're doing it just to look cool, not for performance. Which is contradictory considering that 9/10 people think cross driller/slotted is better.

Check out the brakes on an F1 car, they're blank rotors. $25,0000 blank rotors made from a carbon/steel mix that's heated and cooled for days, but blank non-the-less.

 

lol. preludes are actually pretty big. they have the same wheel base as a supra and the really long. cross drilled and slotted rotors may have less mass but the rotor is still a lot bigger, thats why they dont make it in the stock size. for my car i need at least 16'' rims. and with these rotors and hawk pads...... all i can say is !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! big difference. i mean they wouldnt make them and sell them if they didnt do anything. i guess willwood or brembo are really good at false advertising and taking peoples money.....
