For the fronts, yes. You can either use your RS front calipers with an 02-05 WRX caliper bracket, or you can swap the 4-pots from an 06/07, which bolt directly to the front hub.

The rears are more complicated. 06/07 WRX 2-pot rear brakes require either an 06/07 WRX backing plate, or an aftermarket adapter bracket. More information on this can be found in the first post. Stock WRX rear brakes should bolt right up, but I think they're identical to the RS brakes, so they won't make much difference.

Yeah, I'm inclined to think they're aluminum. The fronts are definitely iron.

Yes its shorter.

I have no brake bias issues. Seems very balanced.

That's a really good question. I see you have a FWD L, and there are some differences between the AWD and FWD rear hub/suspension assemblies. I have seen some catastrophic failures when FWD is converted to AWD without using all the AWD components, which leads me to believe the differences are substantial. Therefore I would not recommend trying to swap your drums to 2pot rears unless you are switching to AWD, or at least to the AWD cars' suspension components in the back.

However, I expect the 4pot fronts should bolt right up to your front hubs. If you have a friend with an AWD car you may want to compare your front hub designs to see if they are identical.
