Rule #1 in the rain is DON'T touch the gators (curbs) when they're wet. They will be slick as glass. In fact, when it's wet you want to move a couple of feet away from the apex. The reason is there is rubber ground into the groove and when it becomes wet it becomes slick as glass. Moving a groove outside puts your tires on more virgin territory that has less tire and more asphalt for better traction. You must also be very smooth with your throttle response coming out of a wet corner.

Assessing your situation will be viturally impossible without video. All we can do is guess. Get a GoPro and start videoing your sessions. A used one on ebay can be purchased for cheap money. Very valuable learning tool to see what you're really doing vs what you think you're doing, regardless whether you're diagnosing a spin or just assessing your driving in general. Then we have something to look at vs basing analysis on a paragraph description.

Are your dry track spins early or late in the session? If early, do you have enough heat built up in your R comp tires? You can't just come out of the pits and hit that 1st turn full blast on cold R comps. It might take a full lap to warm them up. If ambient temps are low, R comp tires may not heat up for quite a bit of the session. If late, maybe you have too much air pressure in your rear tires. Tires heat up as the session progresses and if you have too much air in them at the start, they will lose traction as the pressure increases throughout the session. Monitoring tire pressures during a session is important to drivability.

If you're spinning out at or past the apex, that means your weight transfer is occurring where the weight is moving from back to front, resulting in less traction on your rears. Chances are this is because you're carrying too much speed into the corner and then try to slow down by braking or taking your foot off the gas. This will cause the fwd weight transfer. Remember the famous adage: slow in, fast out. And not every corner is capable of trail braking, but that's a way to keep your car balanced in a corner rather than having a front biased balance (resulting in less rear traction). A balanced car is a happy car.

But as stated earlier, we can only guess unless we have video. Hang in there and it will become more fun as you master your car and track.
