Better tahn before, but I still want to make my car run alittle bit cooler. Maybe oil cooler kit? I already have dual ducted r1 oil coolers but I will research on that.

EBC yellowstuff brakes with motul 600 worked beautifully. NO fade at all.

------For those of you interested: My lap time was ~1:35 which is not too good. I still need to smooth out my braking and follow the line better. Tires became an issue also. (Im running 225/50/16 RE0-1R's) and I need more grip overall but more so in the back.

A big set of dual oil coolers and you will be golden for those 100degF days.

FWIW,

someone may have covered this (i looked some)........but why would you want 70/30 mix in the cooling? any coolant is a real reduction in heat transfer, just 100% water with some 'wetter' is the way to go

you'll get lower viscosity and better heat transfer, put coolant in for 'off track only' but on track days get coolant outa there......besides, coolant is slicker'n'snot on the track surface........especially when its yours dumping in front of your rear wheels........

update:

Same exact setup as before, track temps were in the 60's (farenheit) and max water temp was 91celcius and AT was max 35celcius.

Questions:

-what were your oil temps?
-what boost pressure were you running?
-what track was this on?
-still running stock dual oil coolers?
-any special ducting for your oil coolers/radiator/IC (I know you have a v-mount)?

Glad to hear your setup is working well.

- Here is a one session long vid I took right after I had spun 720+degrees going 110mph trough the chicane.
