Can anyone tell me the difference ie width , offset etc between wrx alloys (2003) and Sti alloys (2004)the grey ones that were originally fitted to WR1 before Subaru UK changed them to 18's thanks in advance.

 

dont know but they DO fit

 

Not sure they're any different in offset measurement. The STi wheels fit over the big brembo calipers when the WRX one's don't, not because the whole wheel is offset out more, but because the spokes are much more curved out towards the outer rim than the ones on the WRX wheels which are straighter.
