DSC has saved me a couple of times on the road for sure .
On the track - I agree with dannobre .
Turn it off in the dry
In the wet it - is a revalation . I found that I was lapping faster than cars that should have whopped my *** . Several drivers commented to me how they could not keep up in the wet . It just gives you so much confidence to throw the car into the corner knowing that if you screw up - DSC will save you.

...correct me if I'm wrong, but in short, traction control is designed to make sure the wheels driving the car aren't moving faster than the road under them, right? In other words, if you floor it and your tires spin, or you give it too much gas on a slipery surface, the TC will kick in to slow your wheels down until they grip. Dynamic Stability control, however, watches all 4 wheels to make sure that the car is only moving in the direction the tires are pointing it. In instances like a fishtail, a hydroplane, or any other type of skid/slide, the SC will work to get all 4 tires back in full grip of the road.
I think you just suck at driving......
......Also rotary engines can go a long way, most of the time is idiots who blow them up

Also, I whole-heartedly agree with you that 95% of the 13b's out there that blow up @ 35k mi is the result of a dipshit driver. My FC ran like new all the way up to 110,000mi - only reason it died was because it was garaged for 3 months in the blazing hot & humid texas heat. I just give rotaries a hard time for ***** & giggles.
Dynamho:
When a vehicle slips, regardless of what kind of vehicle it is, the DSC is going to end up crunching the same general numbers. What makes writting a DSC program eaiser for the RX is the fact that you can be rougher with a sports car than you can an SUV.
Think about it - a computer can figure out how to get all 4 tires back in full grip in less than a second. Making an RX go from big slip to big grip in an instant results in nothing more than the driver getting jarred around. Making an SUV go from big slip from big grip could result in an even worse slip in the opposite direction and/or a roll over. If you're writting a DSC for a small sports car, you only need to worry about one thing: getting grip back. If you're writting a DSC for a large SUV, you need to make sure that getting grip won't result in losing it again.
To someone who knows the mathematics involved, creating systems for both cars is just as doable - it's all basic mechanical physics. It's just that one system requires a little bit of "read-ahead," and thus, more precision, so it's not quite as easy.

You (0.5mv^2) said:
"50/50 is nice for cornering, but not so much for regaining control.

In the first sentence you say 50/50 is not so nice for regaining control but in the next sentence you seem to be saying that 50/50 weight distribution is easier to regain control than a 10/90 weight distribution. So what are you saying about 50/50 weight distribution and its relationship to car control?

^^not really relevant to the conversation, but I think he is saying that it's harder to physically regain control of a 50/50 car but writing the program to do it is easy and so subsiquently it should be just as easy to write the code for a crappy SUV.
I agree that the DSC is great on the road. I've had plenty of times going around corners and the back end slips out only to be caught by the DSC at the same instant I react to it. It calmy plants me back straight and then gives me a little push on my way like a good little boy an a pat on the head. Only intrusive when I'm not paying enough attention. Love it and never turn it off. I imagine the needs on the track are different but I think it's perfect on the street. Gives me just enough room to chirp the tires and throw it around and doesn't totally kill the car when it gets involved. I've never driven other cars with DSC and involked them so I don't know how they react comparatively but I would think they should all be aiming for similar performance. Having the car bog down for 1-2 seconds after it's straightened out is pretty bad.
Once again proof that the Grrmans are not as cool as all the car magazines want us to think they are.

Traction control is standard on all 350Z except the base
Stability control is standard on all 350Z except base/enthuasist

pretty[/i] sure I know the difference between the two, I just have a bad habit of referring to all driver assists as "traction control." I've never been called out on it before, so now I'm second guessing myself on that...
...correct me if I'm wrong, but in short, traction control is designed to make sure the wheels driving the car aren't moving faster than the road under them, right?

If you re-read my inital post, I openly admit to my shortcomings with this car. It's my first manual tranny, and my first RWD car with more than 150hp.
Also, I whole-heartedly agree with you that 95% of the 13b's out there that blow up @ 35k mi is the result of a dipshit driver. My FC ran like new all the way up to 110,000mi - only reason it died was because it was garaged for 3 months in the blazing hot & humid texas heat. I just give rotaries a hard time for ***** & giggles.

Issues with my DSC
Hello fellow RX8 owners!
Just wondering if anyone can help me!?
I'm having issues with my DSC at the moment (DSC dash light flashing and traction control symbol on). Myself and my mechanic have tried resetting the system with success for a couple of hours then the same problem.
With further investigation, my mechanic is telling me it's a faulty steering angle sensor.
I'm in Sydney, Australia and struggling to find that part for my 2004 RX8.
Does anyone know where I could get one?
Thanks in advance!
Cheers
