So have you scraped your diffuser yet? I drove to my parents house for the first time today, and I scraped one of the fins a little on the way in the driveway, but I scraped the fuck out of it leaving the driveway. I ended up scraping up 4 of the fins and bent the furthest outboard one on the passenger side. I guess bcuzracecar even though I never scrape with my SpecE30.
