I'd be more interested in cooling for track than debating calipers. Try a setup like a high quality brake fluid(Motul rbf600, 5.1, Super Blue) + stainless steel lines + master cylinder brace + a race pad + 13 rotor+ pedals for heel to toe+ and some ducting to the rotors like so.
air goes through the side and out through the vanes
I have no Idea what tires you will be running on the track but if you can lock up your tires with this setup you dont really need bigger brakes, imo you need sticker tires. But yeah if you want big calipers for bling factor or you are pushing a good bit of HP and running some nice sticky tires then I'd probably upgrade to the akebono kit myself.
