Jason is one of my favorite SR20 vendors. I've spent about $3k with him now over the last two years I think. Every time I've dealt with him every e-mail I've sent to him got answered (very promptly) and he answered all my phone calls. I recommend him to people when they ask about stuff and that says alot.
Wanna see dedication?
He got down and dirty working on my car for a job that I think he underestimated how dirty and long it was, but never quit, did it right, and charged me exactly what he originally quoted me. Awesome!
