The stock brakes suck. Vented rotors are a huge improvement. I am basing
this project on the excellent information provided by Terry
Oxandale (you should see pictures of
his race car!). He details the use of the 84 vented rotors with the 80s
280ZX caliper (instead of the fatter, heavier 4 piston Toyota truck
caliper). It all made sense to me.
