I don't think you have anything to fear. A lot of cars in AMS were 100% done by Renato, plus he always put the finishing touches on the cars I did as well. Over the years I kinda became known as the GSC / AMS physics guy, but at most I was about 50% of the equation!
Being so handsome and incredibly talented as a driver and comedian, and master of the English language, obviously I became the guy on video .. ;-) ;-)
Plus we're not just thrown in the deep with this engine, as there is documentation and expertise available for Reiza to (ab)use.
