My boyfriend has a wrx 2015 that he truly loves. Unfortunately, our driveway causes a little bit of a scrape when he drives up. It's like a little bit of his soul gets scrapped off! An inch would likely do the trick, can somebody help me pick a kit? I'm fearful of picking from a bad source with my miniscule bit of car knowledge. If it wasn't already obvious, this is a surprise gift 😁.
