I would have just got the preinstalled motor that comes with the pro model since I would not have been spending big money on I high end motor. I have already bought an extra pair of mugen shoes with 2 sets of 1.0 springs, so I will be good there. I have stayed with the stock clutchbell for now, until I get some time to practice on my track once the weather gets nicer. If I get a new clutchbell it will be one of the OFNA vented ones. I already own a LST, so I have many of the basic setup things like high end tools, shock oil, afterrun oil, filter oil, temp gun, diff silicone, etc. I have just found that I now need a new toolbox to keep all my extra Mayhem stuff in
