want to atleast put rims and brake kit off of sti onto my wrx. maybe evetually a full engine and drivetrain swap money permitting. just curious if rims and brakes bolt on without too much hassle. any info would be much appreciated

Well the rims all depend on the bolt pattern. If the STI is an 05+ then no as they have a 5x114 bolt pattern and WRX's have a 5X100. As to the brakes, the front Brembo's will transfer over but the rears need a custom bracket.

and custom rear rotors

not sure yet what year sti is but definetly 04 or older. my wrx is an 04. thanks for the response
