Check your LHS for what parts and brands they carry. Then check your track and see what is run there. Somewhere in there you'll get your answer. Parts support and setup advice are big things.
Otherwise, pick your favourite colour alloy that has decent parts support online in your country.
Pretty much any of the top end kits will be good enough to win. Its all about setup and much more importantly practice.
