So I know Subarus are very picky when it comes to aftermarket parts/modifying. I am looking to do a few modifications to my WRX all of which are exterior and are not related to the engine or involve the vehicle going faster. So I was wondering if anyone knows what particular items or actions would void factory warranty. Not sure if there is just a few basic components or if it's a list of items. If someone could share the things that would void factory warranty or if there is a website that would provide said information that would help answer my question. Thanks in advance to those in advance that provide information!
