Been told by my local subaru stealer that the pff7's on a 2005 sti wont go on a 2003 Anyone know why?

 

Different PCD. The 2003 car is 5x100 and the 2005 car is 5x114.5 IIRC?

Basically, the bolt holes will not line up between the two models.

 

Impreza's up to 2004 had a 5x100 PCD, for 2005MY they changed the STI to 5x114 (I think, something like that anyway).

 

So occasionally your 'stealer' saves you a few quid by stopping you buying stuff that won't fit eh

It it helps the PCD's are unchanged on the WRX (AFAIK), so if you find rims that come off even the latest '06 WRX they will fit earlier ones..
