well, imho...i think you should ask yourself how much you want to spend. if you're willing to put in about 3 to 4k...trust me my good g35 fellow...you will see the difference with brembos. im not talking about the brembos that infiniti offers. for the price they ask...contact one of the car boutique centers in the country...and theyll install the brembo gran tourismo kit or even better ones. the brembos that infinitim offers is one of the cheapest in the line of brembos and they charge a lot for it to make money off the name. if i were you....save up to 5 or 6 grand. with that...put nice 18" wheels/tires, eibach springs, and nicer brembos than the ones that come on the coupe...once you do that....get on a highway and see the difference. youll probably corner better than the coupe. enjoy.
