I was driving on a wet and slippery road today in Caifornia and my 93 NSX lost control. I started spinning until hitting the curb on the side. Luckily, I only got a flat tire. However, one of my sideskirts came off. I am going to order a bodykit or something to replace it. Does anyone know why it lost control?
PS: Drive SAFELY!!!

The same thing happened to me three weeks ago, and it was like the worst nightmare I've ever had. My car spinned out because the stock tires were almost flat.

"Does anyone know why it lost control?"

Umm... slippery road? Rear wheel drive? Braking or lifting at high RPM? In a turn?

There are lots of factors that can cause you to "lose it"... but you didn't tell us enough of what you were doing at the time (and at what speed, etc.) to derive any possible answers for you.

Almost flat (not enough air pressure) or almost bald?

Obviously you need to maintain proper air pressure in the tires. Remember, particularly this time of year, that as the ambient air temperature gets colder, the tire pressure goes down, so you may need to add air to your tires to adjust them if you last measured them when it was warmer outside.

Also, the OEM tires have a reputation for being very good on wet pavement when they have a lot of tread, but not very good when they are worn.

I agree that your incident could have been caused by one or more of a lot of different things, and it's difficult to pinpoint any single cause. "Driving too fast for conditions" comes to mind, too. Most people underestimate their traction (and may drive slower than they need to) on dry pavement, and overestimate their traction (and drive faster than they should) on wet pavement.

I think Jack spin out when going straight. Right? In that case, it could be that one rear wheel suddenly enter an area with lots of water, causing it to completely loose traction, while the other wheel still has traction. So the car suddenly turns, and Jack probably didn't catch it in time, so the car spins.
Just my guess...

(First post here, please be nice...)

I wanted to add that if you haven't already, you should have the suspension on that wheel checked. Once upon a time I kissed a curb while fishtailing in my M3 and only discovered my lower control arm was bent *after* a spinout at the track!

If you are running low tread -especially with wider tires - the NSX will hydroplane increadibly easily because of its low wieght. The low polar moment of inertia, because of the mid-engine layout, will also make it worse. It is really, really easy to get the car into a spin when the rear loses traction. I have owned a long string of different sports cars and I have never had anything more willing to hydroplane and wiggle, even when going straight, than the NSX. Still love the car, just don't like it's wet weather manners.

Thanks for the input guys,
I really appreciate it! Just a few words of caution. Try not to drive in a bad weather! I really thought the "TCS" system is targeted for the car to drive in harsh conditions? Why is it not working?

Your TCS may very well be working, but it can't save you from the laws of physics.

You can test it on a wet parking lot. From a stop, floor the accelerator and see if the green TCS light flashes. (You'll probably be able to feel it cutting the power briefly, too.)

Based on what I have seen, the main reason for this to happen is either low tread on your rear tires or tires which are not good for the rain.

Don't run the car in the rain when you're down to the wear bars on your tires. With good tires I have no problem running at normal highway speeds even in heavy downpours. But as soon as the tread gets low the rear gets twitchy in the rain.

The reason the rear gets twitcht in the rain with low tires I believe (I have not done exhaustive experiments to prove this) is the alignment setting on the car, particularly the toe settings.

While great for dry conditions or as long as you have good tread on your tires, in my experience it will cause the rear to become unsettled if you lose traction on one side briefly (slick spot on the road, uneven road surface, etc.) AND your tires on the other side are not up to the task (low tread, not designed for wet weather, etc.)

The obvious solution again is that if you plan to run the car in the rain, use tires that are good in the rain and make sure they are not worn out.

All these problems become even more magnified if you run in snow.

TCS does one thing and one thing only on the older cars: It limits the amount you can spin the wheels with the throttle.

On the newer models it will also maintain some throttle if you lift in a turn when you shouldn't have.

That's it! Neither it nor anything else can change the laws of physics and prevent you from spinning a car in every situation.

Anybody in Northern California knows how wet it was this weekend. Saturday I drove from San Jose up 101, across the golden gate, over to Napa, and then took one of the best twisty roads in Nor Cal, from Napa past Lake Berryessa to Davis, Ca., where I live. This entire drive was in the rain, varying from downpour to drizzle. This was the first time that I had the car in the rain, and frankly I could not have been MORE impressed. The car broke loose many times in the turns, however just about every time it was intentional, I was trying to learn limits of adhesion and the manners of the car. TCS was nice, but the behavior of the car was predictable without it. However, the car never broke loose in a straight line, even under hard acceleration to pass other vehicles – even when very wet. Going up 101 I was cruising at 85-90 MPH (traffic was light once I left SF) and the car never felt anything but stable, even when encountering standing water. One other incident of note, the dreaded “deer in the road” required me to slow from 110 to 20 MPH, obviously straight line. No problem, especially since the deer finally decided to move. Note, I have almost new tires.

Jackmac, could your situation have been driver error, not the car? After my experience this weekend I feel the NSX is a great handling car, WET OR DRY. The best comments I have read in this thread come from nsxtasy, you truly can not defeat the laws of physics. I do not agree that wet weather should be avoided, you should spend time in your car in all conditions and learn what it can and can not do at a gradual pace, making sure the car is set up correct beforehand. It is not realistic to expect the same level of performance in the wet.

Sunday was my first real drive in the rain as well, but no problems to report. My NSX held up well in a real heavy downpour. I was heading down the carpool lane just under 80 and the only time the car felt a bit twitchy was when the tires grabbed a groove towards one edge of the lane and started to follow it.

Gave it a quick wash to remove the muck on Monday morning...

'98 NSX-T, thanks for your post about the ride last weekend. For me, this was not the first time to explore the cars' limits in the wet. Being the lead car that day (FSTR N U) was pretty exhilirating, not knowing the road or the surface conditions, but I was always certain of the car. In my opinion, the NSX is as stable as any other passenger car in the rain. Even at high speeds. I have driven at the track in conditions that were worse than our 101 North Coast drive and found the NSX to be very predictable in the rain at speeds of over 100 mph (with OEM Yok's).
I think it is a disservice to other drivers to try to dissuade them from driving simply beacause the weather may change for the worse. Instead, I urge drivers to learn how their cars behave in wet conditions so that they will feel more at ease in adverse weather.

ChopsJazz, I agree.

Regarding the drive, I assume you are referring to the Pantera Club drive? Unfortunately, I was not able to attend and was not part of the group, but hope you guys had fun. I think some of my friends from the Sacramento Chapter were planning on going.

The drive I described was solo. I had business run longer than expected in San Jose. I tried to make it to the club drive but was late, so I decided to do my own "fun run" and take the long way home.
