I saw a set on Ebay, it went for about $150, and theres some on there now. last time i checked, they were about $75.
im just wondernig, if theyre supposed to bolt straight up to a MA71 or if it how it mounts up. i dont think ive actually ever seen any installed on the car..
heres some that they just put up for sale
JZA70 Brake coolers
i dont know if they actually duct air directly to the rotor or just direct air to the vicinity of the brakes...
