The big thing is to make them effective. I had the huge 326 fronts and 298 rears on my S13 and that car didn't stop worth a shit. I think big twin-piston fronts, stock rears, and Hawk HPS all around will be much better.
My only thing with Q45 brakes they have an even worse front brake bias than Z32 fronts according to everyone on NRR. I've been meaning to do the Z31 bracket / Altima rear rotor conversion to shift a little more braking power to the back of the car (whole set up is like 60$). I have Hawk HPS in my car and have yet to have a problem with them. And hardly dust at all. But I've been wanting to try Carbotech for the next set.
The nice thing about Q45's is the pedal feel is pretty much stock. I've never once felt my brakes felt vauge or squishy like some of the guys say about their Z32 set ups. I think some of it has to do with the booster/master cylinder being different.
