i have followed these guys a little bit and only pertaining to the razzle dazzle sand car. they can build engines no doubt but they lack some basic fundamentals on suspension design and no idea where they are getting their info on those trans.  this sequential up grade video is entertaining for sure. will be interesting to see how that rear end works out. not just because they are running 930's and proposing to turn it up to 700 hp but also because the pivot points were off a fair bit before the new trans. they really need to add some frame work to protect that trans too!

Aaron is badass.
