new e series member

[mad-ef]

just put a deposit on a ef fairmont today & will pickup on Tuesday so as of tuesday i will be a e series member instead of being a b series here is a description of the car i am buying
This car has been converted to a T5 manual. It has tinted windows, hayman reece towbar, sports suspension, XR8 rims, mandrel bent high flow exhaust, K&N filter with bigger air intake, pace maker extractors, Uni-Chip & jimmock dev 5 port & polished head which includes dev 5 cam, vernier adjustible gears, bigger valves etc
which is producing 160rwkw at the moment but the standard diff is holding it back what would you guys recommend with what ratio diff to put on this bearing in mind that i still want this to be a everyday drive as well as taking to drags. here are some photos
