Important. People who plan to do Q45 brake upgrade.

It's true you got to drill extra 3 holes on a rotor to fit it into your 4 lug s13/s14.But also, mostly you will need OEM Rotors too.

Diameter of Stock S13 hub is about 143.5 mm.Okay, inner size of OEM S13 and OEM Q45 brake is 144.5 mm.Rotor fits fine because inner diameter of rotor is bigger than the hub.

When you get a rotor, you have to becareful that some of aftermarket rotor's inner diameter is 142mm. It fits to Q45 hub, and 5 lug S14 hub, but it will not fit to S13 hub.

Get oem. Oem rotor has 5 lug holes and 2 extra small holes for screws, most of aftermarket rotors only has 5 holes.

i can say that this varies. i have aftermarket rotors from bennet auto supply...............drilled four new holes..............fits up perfect..............remove the splash shield/dust shield thing and your golden. it is tru that oem rotors may be the safest way but see what the cost is before going to the dealership.

yes. and I said, "Be careful when you get after market rotor" which doesn't mean don't get aftermarket rotor.

i hope this help little. Cuz i waisted 30 bucks

or you could have a machine shop take off the few millimeters' difference. can't POSSIBLY cost the difference between OEM and aftermarket. i'm planning on using autozone or the like. good to keep in mind, thanks.
