... see the thing is I enjoy the stock ZTT performance and I want to get bored of it first before I buy those upgrades, but good point thanks. About the brake kits, I am getting all mix up on this some say I needed a big-one. I need that streetable and beneficial to the track, i heard a lot of good things on ST Brake kit and I know someone that use Porche brake rotors, caliper and few things too, is that any good at all?
