Brake Upgrade

Keep in mind that the great majority of braking is done in the front. So if it was me, I would upgrade to 13" cobra/mach/bullitt brakes up front, as well as slotted rotors and some good pads all around. The rears arent a huge difference, unless you qwant the look.

for suspension, would you be looking for bang for the buck, or pricier upgrades? you could go coilovers at one end, or C-springs at the other. all depends on the ride, price, and ride height you want and need.
