Just like my other topic... My 90 DX sedan has warped rotors, I have a 88 CRX Si parts car, are these rotors compatible?

 

here is how i find out if they are the same....

go to http://www.racerpartswholesale.com/ and look up hawk brake pads. then click on the "street application chart and purchasing" link. then the "honda" link.

here is what the application showed...
1991-90 CIVIC 3&4 DOOR-EXECPT 4 DOOR EX HB218.583
1989-88 CIVIC COUPE CRX -DX & Si HB218.583

so it looks like they will be the same since the brake pads have the same part number. therefore the rotors should be the same size.

 

Yes, They are the same!
