The new ACR's do not have diff coolers, but the X diff coolers bolt up to the Gen V's without much fanfair.

I know that we had one other owner at COTA the day I was there with them that mentioned to me that he saw some really high temps but after we got to talking he told me he was running the S's at COTA in second gear (he would have run that entire section at like 5000-6000 rpm). He went out next session and ran that stint faster in third gear and didn't see any where near the temps he saw running that section in 2nd.

The new ACR's do not have diff or tranny coolers, but the X diff coolers bolt up to the Gen V's without much fanfair.
