Yes AutoX. I was running the first half of the day staged and waiting. The second part on the flip course was pretty much back to back runs for about an hour and some change. Its a really good way to get to learn the car and learn how to control it I think. I will say this, even though I didnt really see fuel starvation... If you spin the car completely around it will stall and be a little hard to start for a few seconds. lol

Say it with me!

Clutch in on a spin! Clutch in on a spin!

Same, although I found a strange thing with my group that I go out with:

They never bothered to explain the REASONING behind "In a spin, feet in". If they had, I may have survived my wreck at VIR.

Does that mean that you're posting... from beyond the grave?

Correct.

Be spooked.

Do those Carbotech pads make a lot noise and dust or are they ok for street use too?

They make a lot of noise and dust. No, they are not OK for street use, because they only work properly at temperature.

Ask bladesofchaos (he has special characters in his name, cant remember what they are) what happens when you use XP8's as your DD pads. When I took them off of his car, the material buildup was so aggressive, they dug what were probably 1/2" wide, and 1/8" DEEP grooves into his brake rotors and ruined them, simply because they werent getting hot enough to shed the pad material properly.

There ARE street-style Carbotechs. Just not the XP line...they are for the track, and track only.

thanks that's GTK! My Z is not a daily driver but most, if not all driving is on the street. I'm changing the front rotors out and was wondering if I should change the pads while I'm at it. If it's going to be dusty and noisy, I'll just keep the OEM pads and swap them out if I plan on a track day.

Just swap the pads out the night before your track day.... no reason to squeal all summer

Edit: i run XP8's all the way around. Perfect for summer tires.

I never had trouble streeting XP10/XP8s aside from dust/noise. They worked great even cold. I didn't drive the car a ton on the street though so that may be why I never had rotor problems. Swapping to Bobcats is where it's at though.

It's not necessarily recommended to run the same compound all around. Better to run a more aggressive compound up front. This will cause the front end to lock up before the rear end, preventing a mid-corner breaking spin. Just FYI..

Blades used his car as a DD, so...that could explain it.
