Good luck! How has it handled thus far? Have you been able to drive it okay? I remember reading an article a while back (it was by one of the Ryans....I think Cavaleiri) where he provided good tips/setup to tame the vehicle for club-racers while they gain experience with it. I'll try to find it and send your way.
Are you sticking with that 053 on your P5? I'm throwing 053 on my Savage (F4.6) this afternoon to test it out. Not sure how I'll mount it but the header looks like it will just barely fit.
