I have a 99 V A8 4.2 sport and I'm wanting to uprate the brakes and suspension but don't want to anything hard. Is there a difference between S8 suspension and the sport that I have and what size are the brakes on the S8 and will the fit my car(what would I need) I have brembo calipers like on the S8 but is it pointless putting them on, would I be better going for a Porsche setup. It would be great if some one could give me some advise, cheers.
