I bought an ST insurance wreck and converted my sedan to ST spec with everything I could, the entire powertrain, suspension and even interior including the nav, apple car play and so on. I love ripping 3rd gear tires loose with my E30 tune from Jason. I'll upgrade to big turbo when the time is right. I love that even right now, I can merge onto the freeway at over 100mph if I need to get into fast traffic.
