Yeah I like my Brembos too but I'm not sure I would have spent the money if I was not going to the road track.
To the OP, I'd suggest you look at wheels and tires first, and consider the brake clearance as you select wheels. The spacers throw off the correct geometry / offset and you might need so much spacer to clear the brakes, that you would move the tires outside the wheel well (not sure how much is needed).
The one thing I don't want (read: can't justify) is buying new rims to fitt new brakes.
maybe I will look into rotors and pads that are more head resistant.
Than again, wider rims and tires look damn nice :-) ...... I am afraid the mod bug got me again :-(
