as far as motors go the 750 hondas are the most used to date but a few 600 are showing up. you should be able to get a full season as long as nothing breaks.
i think just about every chassis has won.
tires dry slick you can burn up a right rear a night. last year tracks were wet run same tires all year. pavement new tires are everything.
10 to 12 psi fronts 3 to 8 left rear 10 up for right rear.
any more question you can call 812 871 1030 will help you as much as i can
