4. wheel hop frequency? seriously? on zilvia?

5. it doesn't matter

i use aluminum 30mm. in front with 350z rotors. when i replace my rotors, i'm probably going to try some two piece, slotted rotors for weight savings and cooling efficiency, and upgrade to some ferodo pads and real tires. i do track the car, probably at infineon again.

having driven there twice already i should be able to feel the difference in equipment and stopping power, even though i'm not an elite driver by any means

most people here, however, will never use their cars to the extent necessary for these concerns to matter
