Now switching to the newer Yoko AO 48 Tires (40 TW) 285/295 18's with Baer 6 piston 14" all around. I'm considering the late 2nd gen dual diaphram booster & 1 1/8 master and already have a rear bias valve to use instead of a prop valve.
JT, you'll want more tire than a 255 street tire if you're going to try and run fast at Road Atlanta or you'll end up with greasy tires by mid session. I've run there several times and it's one of my favorite tracks. Without good brakes & tires you'll have to brake early for turns like 10A which costs lots of time.

John, how did you like the Porterfield pads?
