I'm gonna say yes. There are two "standard" brake size offerings from Honda, the 9.4 inch found on the CX, LX, DX, SE models, and the 10.2 inch found on the EX, SI, SIR, Integras and some Del Sols.

the difference is the CDN Si (EX in the states) had rear drums, while the SiR (Si in the states) had rear rotors.

96-00si, sir, 1.6El all have the 10" rotors, and calipars, booster, master are the same. If you really want to make sure just take a tire down and measure the disk. Its either gonna be the 9inch or the 10inch

ya~ you can tell the difference between the DISK and DRUM very easily
so CHECK the rear see if you have a dick or drum.
SIR suspension can sometimes means the shock and spring only.
