There won't be enuff to go around thats for sure, there isn't 5X100 hardware to be had.

You didn't read my post or his. 04-11 STi/STI Front Calipers fit. 04-07 (at least) STi/STI rear calipers fit.

However, fitting doesn't mean working correctly due to the caliper design and mounting location, UNLESS the STi/STI calipers have a second spot for a bleeder on the opposite end of the caliper. The reasoning for that is that the calipers are differential-bored so they are directional. If you keep the left on the left but move it from the rearward side of the rotor (like the STI is) to the frontward side of the rotor (like the BRZ) the pistons will be correct but the bleeder will be on the bottom, which isn't good. If you swap sides, the bleeder is fine, but the piston bores are backwards, which also isn't good.

So literally the *ONLY* 2004 STI dependant part are the rotors. Nothing else.

A much cheaper upgrade will hopefully be newer LGT front rotors and caliper brackets (and maybe calipers if the BRZ calipers have smaller pistons and/or don't fit on the LGT brackets).

And that's assuming a brake upgrade will be needed. It absolutely WILL NOT be needed for the street, and even on track cars will only be needed if the OEM brakes can't keep up with the repeated high speed stops, assuming the car has enough power to even experience repeated high speed stops without cooldown (assuming track pads and good fluid).

If you are doing it for looks none of this would probably concern anyone though.

Price difference for the same model and size wheels just because of the bolt pattern btw? Example? I've never seen that.
