ok, well im either gonna go with the KDW's or Bridgestone Potenza S-03 Pole Position tire, but 48mm offset rims isnt bad or going to effect my steering/handling correct?

thats damn near stock. shouldn't effect anything unless they are overly heavy.
I say the noise from the KDW's is subjective because a lot of people hate the road noise from the OEM Potenza's but I generally don't notice it. Same with the squeal from the OEM brake pads. I hardly notice and even when I do it doesn't bother me.

Chet, did you get those black ultraleggeras? I am so tempted to get them for my summer rims. I just can't decide between Oz Ultralegger, Axis Reverb, or Tenzo DC-6, all black for my BB.
reverbs:
tenzos:
I would also go with the 48 offset ... right now I have 40 with the SPYN rims and it feels fine but I'll also be happy going back closer to stock. That and the fact that the spyns are 25.5 lbs

Yeah the oz are. Those rpf1's are light, 18 lbs. Would you go for staggered or just 35 (or 45) offset in front/back?

15mm change in scrub radius is significant. It will almost always change steering feel significantly. Mazda's product development engineers will want to give you a massive wedgie when they hear about you doing it.
Different platforms have different tolerance for change. I've driven an E46 that was ruined by an 8mm difference, other cars that were decent with 11mm change. If a wheel that's otherwise the same with 2mm change is available, why go with the 15mm change? If you want to fill out the fenders cosmetically, 9.5" +45 et all the way.

but do u mind explain urself on how the offset can make such a "huge" different feel as you said?
do u know what's scrub radius?
from what i know from school, it can only be affected by SAI and camber. Since there are not adjustment on SAI on our car. only thing that really affect the scrub radius would be our camber setting.

Moving SAI or camber will change both the center of pressure of the contact patch and the point at which the steering axis intersects the ground (claimed as the "Dave Point" by my friend who is now a Mazda product development engineer). Your school assumed you are doing alignments, not changing wheels.
