and I would most certainly spend my hard earned on them, they are an excellent setup for the price. I have them on my stagea, 350z and race car (when I am allowed to by rules)
anyway, when I put the set from my race car onto the stagea I was replacing 32 gtr calipers. the 32 gtr caliper sat a mm or 2 closer to the wheel spokes than the ksports do so if that is where you are worried about you will be fine. they are smaller and squarer than the brembos.
If you mean clearance to the inside of the rim, I can't answer that for sure, depends if you mean 330mm or 355mm rotors, but it will probably fit. I have fitted the 355mm set under 17" weds so pretty much any 18" wheel should be OK.
