RC, this is awsome car!
Personally manual is for me the way to go! BTW, rear axle differential is available for manual only! So, manual will(or is!) be faster around race track then TIP! I like te look and specs... TIP is faster only is straight line and in the hand of experineced driver. On curvy road manual will beat TIP for sure, despite the fact the Porsche probably did fantastic job on TIP this is old five-speed TIP... What about down changes on tip?
Any way, manual is the one for me!
