I agree to turn the TCS off at all times ,wet or not. To intrusive IMO I've got a JDM so they might be different but had to drive it like a granny for it not to light up, even on uneven surfaces coming onto a highway the bloody thing would light up and behave irratic. What really made me decide to put it off always was when I was entering a roundabout (bigish one) at sherrywood industrial estate outside of Dublin (if you ever been driving in roundabouts in Dublin you'll know what I'm on about) saw a car coming out from the DELL office and felt that I'd easily make it through the roundabout, coming into the roundabout I looked again and saw that this dude was belting it around (like everyone seems to be doing over here), so needed to give it a bit of power and the TCS light flashed, car lost ALL power and shugged out in the roundabout (freaky) was almost hit by the oncoming car in the process. THIS wouldn't have happened with it off, a slight wheel spin (POSSIBLY) and then adapt power accordingly and easy avoided the stop at the next junction getting grief from the guy that almost rammed me. He would have been in the wrong btw if he'd hit me (off topic but still). And this wasn't anywhere near dangerous until TCS destroyed my pants It's very possible that my TCS isnt 100% but instead of fixing it I rather drive with it off and adapt my driving style to whatever condition there is, people need to get trained up to handle the power these cars provide and drive with the head. It's all about giving power nice and slowly and not upset things to much, tried driving last winter with the TCS on in the snow (late December with loads of snow) That again proved it useless, couldn't get anywhere. Off TCS and spin a bit to get going and then camly move on I can't provide input on the LSD replacement that I've got since I've not really driven it properly since I got it installed. Don't think it's that expensive mod to be over looked though. Hoping it be well worth the monies I spent on it. (got a feeling that I'll need to retrain my brain driving the Z once I get her back though )
Going around a race track on a motorcycle does help to understand smooth power delivery, nothing worse then a high side on a bike.
As a side note, people with dodgy TCS's might have crappy tires or to high pressure or even @*!# camber settings. I had neither but not wide enough
