AutoX in the Rain

Z1NONLY

The only thing I would do is soften the suspension a bit. (if it's not too much trouble) In the wet, you will get less lateral g forces and thus less deflection on your tires' side walls. Lower pressure may be beneficial.

My 350Z on Kumho XS's in a lot of rain:


It felt like I was driving a shopping cart with those "spinny" wheels at all 4 corners. With water on course, the same input can give you wildly different results from one spot on the course to the next. Traction was "like a box of chocolates" and steering response was like a game of "Marco Polo".

I can't imagine any tire with tread on it being as bad as Kumho XS's in the wet, so I expect your RE11's won't be as bad.
