What they said - RPi is also a Board sponsor and they should have a link to their website in the list of advertisers on the right side of the thread listing page. In any event it is: RPi - Race Precision, Inc.
I also personally recommend the RPi scoops with BMC filters. Be sure to order block off plates too. They are a separate order item (but very inexpensive). If you call them, ask about their trunk placards if you have a sick sense of humor.
