Can anyone tell me if the 2004 17 inch BBs rims will fit on a 2004 WRX wagon

 

Yes they will, 100x5 bolt pattern.

 

Yes, and they will let you run 235/40/17's. Wagons and GC/GM's work great with these wheels, especially if you want to run a decent width tire for the track. I recommend 235/40/17 Toyo RA1's.

 

Thanks for the info. I am selling my stock wheels and the guy who want them has an 04 wagon. I wasn't sure if the off set was the same.

 

They will fit fine...too bad they changed it for the 05's...

 

WHAT??? 2004 = 5x114 bolt pattern. 2005+ = 5x100 bolt pattern!

 

^^ WRONG! You should verify your info. before you try to correct someone else, especially since that person was right to begin with.

CORRECT INFO:
04 STI=5x100;
05 & 06 STI=5x114.3;
2002-06 WRX 5x100.

And if you still think that you're right after this post, then you should also note that your atmospheric-bov gives you 10 whp, and your cai gives you 50whp and gives you full boost at 500rpm.
