My First Hydroplaned This Afternoon

I should take a session of High Performance Driving School. I mean, I'm not a terrible driver but I have plenty to learn.

they are not bad...they have around 65% thread left. i think they are not all season.
i have to check them out.

what helps when oversteer happens in the rain, oppposite lock and no throttle and the car should correct itself pretty quickly.
you might have oversteered and then hydroplaned if the car kept sliding depending on the grade of the road.

I noticed with the ZT (zexel-torsen) differentials if you let off totally - meaning clutch in, feet off gas, it tries to straighten itself as long as you dont give it too much steering input.

Although, if you read his post he does say "clutch in" which is different from letting off with the throttle. There's no engine braking and actually that would be best from a control standpoint... to have all the wheels spin at the same rate with the same drag.
Agree that lifting off the throttle to cause engine braking will slide the back around... but that's effectively the same thing as giving too much gas as well. Perfect throttle maintenance is crucial (if you're going to do that), but extremely difficult to do if you're starting from a sudden over-revving rear due to broken traction. You have to back off traction perfectly. That's what a system like the Racelogic TC does. It works great, but I can tell you that few humans have that kind of reaction and execution prowess.

FYI... not trying to be a Mr. smarty pants but that was not hydroplaning. Hydroplaning is when you are moving fast enough to actually ride on top of the water. It is quite the experience! Happened in my CRX a few times when hitting few inch deep puddles that had collected under an over pass while doing about 80 mph IIRC. You lose ALL steering control until the tire reconnects with the road.
You simply lost traction, I highly recommend that you go find an empty parking lot both wet and dry and find out exactly where the limits are and practice correcting them. Tapping the brakes or even lifting the throttle during a slide will upset the balance and cause the fish tailing that you described. Best thing to do is keep the gas steady and point the front wheels where you want to go. You should also find out how long it takes to stop in both wet and dry under FULL braking. You might feel like you are abusing your car but it might save your life someday.
I wish it was mandatory for everyone on the roads to take a driving class (in their own vehicle) to know their cars limits, it would make the world a much safer place.

Yup, unless you're running on slicks, it would be impossible to generate the thin layer of water necessary for hydroplaning at that speed. Even then, at 15 mph I would think a slick would squeeze enough water out to maintain contact with the road. Hyrdoplaning requires enough speed that a tire that can't evacuate water effectively and begins riding on top of a thin layer of water. Usually this would be 40 - 60 mph. The fun continues until you lose enough speed that the water can no longer support the weight of the car on the surface area of the tires. Same principle as skim boarding or water skiing.
This sounds like the OP was caught off guard by the massive low speed torque of the S2000.
Solution = learn to drive.In the interest of complete honesty, I did the exact same thing with a Vette on a curving on-ramp at about 35 mph in the the rain. I knew the Vette's limitations well. Wide tires and massive torque with heavy throttle tip-in are great on dry pavement. Not so much in the rain. Anyway, I was using what I thought was near nuetral throttle input. Oops, think again! Three seconds of heart pounding excitement while I got a 360 degree view of the horizon. Luckily I pulled it out of the spin and continued on my way without ever leaving the road. Felt like a complete a$$ though.

Clutching at the first sign of traction loss at the rear is poor practice even for the uninitiated. Lift abruptly or clutch and you're just asking for it.
I was referring to the situation that the OP was in... when it's too far gone to save.
The problem with new drivers is that they miss the first, second, and third signs of traction loss... by that time, with that amount of driver skill... I think clutching in is best.
I mean, C'mon, how ham-fisted and lead-footed to you have to be to lose control at 10mph?
