I'm getting very frustrated with my car. We've had 5 events and 2 were full downpour events. I've place next to last and mid pack respectively. My car just does not want to go fast in the rain. I know it's not me since I jumped in someone else's car and beat my own time and almost tied the owner.

My setup:
205/50x15" Azenis (almost new, almost full tread - 2 autocrosses), 15x7" Kosei K1s, 350f/400r Ground Control springs, Koni Yellows, Skunk2 camber arms (-2.7 front), Ingalls rear camber kit (-2.0 rear), ES suspension bushing kit, and Neuspeed rear strut bar.

The course:
weather was in the 70s, course was DRENCHED all day. Asphalt is cured. We haven't run on the lot since last month.

I tried everything:
1st run 38f/34r, shocks all soft - 36.1
2nd run 36f/32r, shocks all soft - 35.8
3rd run 35f/31r, shocks all soft - 35.7
4th run 35f/31r, 1/2 turn front, 1 turn rear on shocks - 36.9
5th run 38f/34r, shocks all soft - 35.7

Then on my fun runs:
1st run 42f/38r, shocks all soft - 35.9
2nd run 41f/35r, shocks all soft - 35.3
3rd run 40f/35r, 1/2 turn front, 1 turn rear - 35.7

So what's going on here? I keep hearing you should go down in pressures when it rains. But when I increased my pressures my car was a bit easier to turn (now I admit NOT great, but turned better than before).

In the dry I get my competitors by at least 1/2 second consistently. But in the rain I loose bad.

Thanks!
