Those times are similar to our (COMSCC) current class records for STGT and SPB set back in 08. We fully expect the records to fall this time around as cars have got a lot faster, and the last couple of times we have been there it was cold and rainy. So if you feel like doing back to back time trials at Mosport you are more than welcome to sign up

I happened to have some x10 front's so I put those on and the car maintained a better braking balance through the run, but I could not brake as hard without feeling the front brakes give up towards the end of the the braking zone at the end of the longest straight.
I use to run x12/x10 on my c6 z06 without any issues, but that car is lighter than the 370z and it does have brake cooling vents for the rear.
I created my own brake ducting for the 370 because the stillen kit was not available at the beginning of the season. I will be ordering the stillen kit just to get the mounting plate for the rotor so that the hose will pump air more towards the center of the rotor. The solution I created involved cutting a hole in the dust cover and riveting a flange to it. But the air is pushed more on the outer portion of the rotor than the center. |
I find it interesting that you are overheating the rear first because I normally get the reverse effect. I tend to overheat the front pads and then the rear starts to lock up. The Stillen brake ducts certainly help, but they are a little undersized to be ideal. The effect is positive, just wish they were 3" and not 2" as it would be over twice the air volume.
