AutoX in the Rain

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.

Wrong.

By increasing the tire pressures, you reduce the contact patch and help reduce hydroplaning. Had a rain event last year, one run at the normal pressures I run and the next with 4 psi more all around. The higher pressure was noticeably better.

I said "may be beneficial" because conditions and tires and setups vary. I formed that view over countess wet events, and at least 6 different tire brands on the Z alone.

That being said, I don't recall running RE11's in the wet. I don't assume that all the dry runs I have had in different cars on those particular tires make me informed on the re11's wet behavior.

My advice is the result of what worked best on most of the tires, at most of the rain events I have driven in.
