Id recommend getting a tranny cooler asap.
I did not drive DD in them, but did get caught in the rain a couple times, just went really slow, but it was sketchy at times.
The downside to good track tires is that they all are not going to be "good in the rain" i would highly not recommend counting on them for extreme weather, but you can get through rain if your very very careful. All in all though the gforces and mt 2s should be better then what i had in the rain.
But you def will see better 60ft times
