    I guess I'm gonna go against the grain here and say the Z32 doesn't slide out easily enough. Generally requires more input than a silvia or 180sx or whatever to get it going sideways.

    Mines always to the left. I'm guessing my suspension settings are off.

    dude your question is like asking how long is a piece of string... there's so many reasons a car can slide out while turning... you gotta be more specific... it's hardly a design flaw, more driver technique/error as the others have said.
    but be more specific and you might get some less-sarcastic answers...

    Dam i was going to ask the same question about grip. Mines not that great in the wet even with good 275's. It also starts to spin at about 55ks if i floor first in the dry. Does anyone know whats involved in changing the camber angle?

    probably best to let a wheel alignment place do it. my zed was running -4 degrees camber and +2 degrees toe (this is on the rears btw...) so a good wheel alignment (took it pedders) fixed it all up for me.

    Charger

    Many years ago I had a Valiant Charger with a big hemi engine and must admit the zed handles almost the same lotta weight up front and light in the a .....got used to handling the Charger and treat the Zed the same.

    wet= low grip (less friction b/w tryes and road)
    300ZX= rear wheel drive, high powered

    wet + 300ZX = wheelspin if you don't control your throttle inputs (and steering inputs) properley.
    even in my NA, a wet road has to be treated with respect. Gotta be very gentle when bringing in the throttle, same goes for steering inputs.

    yeah i get that...but does weight distribution have anything to do with it???

    what....
    if i wanted smart ass answers i would have titled the thread...

    'post your smart ass answers here'

    :bash: :eek: :D :p

    thanks to the people that gave me an answer.....this thread only had to be 5 posts long to answer my question...not 30....sorry if im not as knowledgeable as the rest of you but not all of us have the 'smarts' about this car like a lot of you have :eek:

    The zeds are quite heavy for ther size:cool: the lighter the car the more grip you get ;) the less weight on the car the less the engine has to work to get the car moving and less strees on the tyres = more grip :) simple enough

    vvt gives lots of low rev torque

    The valve timing gives a lot of torque low in the rev range, that can break the tyres loose.
    My car had 275 tyres on and I found they were too wide; massive difference between dry and wet grip.

    I use the hold switch in my auto when its wet, given sydney roads are so rough and slippery. Plus theres diesel on most of the turns and roundabouts.

    Its relative too. They are a low and stiff car. You dont get too much warning like squeeling tyres or body roll to gauge how hard youre pushing it.

    I have 2 x 2+2 Zeds, an N/A and a TT. Both are manual. They handle wet conditions differently but both are very stable.

    I suspect the 2+0 Zeds with a shorter wheelbase are less predictable at the limit (or to sense where the limit is). The NA is easier to lose traction low down than the TT and with the TT it is easier to lose traction coming onto boost.

    I took the TT to an Eastern Creek skidpan event that CAZ1 organised a few months ago. It stuck "like sh_t to a blanket" and I had to spool up the turbo with clutch in to break traction, or use the handbrake. Then, as soon as I backed off even slightly, it gripped hard and damned near threw me out of the car. I did not expect this level of grip on the wet surface. I have to say, if I did it again, I'd take the NA.

    Of course, the first 24 hours of rain after a dry spell is the most slippery until the oil slick drains away, and a time to be careful.

    Cheers,

    Peter

    I second that. Ever tried "drifting" and I mean "drifting" in the true sense of the word - not just power oversteer. The zed is one of the hardest and snappiest cars to get sideways and to hold it. There is so much chassis grip in a 300zx its not funny.

    they handle beautifully in the dry (except when i go round round abouts a tad too fast and flick the tail out a bit on the exit ;) )...what, work is a bit drab sometimes so i gotta have fun when i can. And yeah i've found the z can be a little finicky in the wet. Doesn't like puddles at 100 km an hour or sharp turns. Skims over and nearly pulls me off the road sometimes. It's not too hard to get out of a skid or a slide. I find it's best not to back off the throttle when in a slide, and don't plant the brakes.

    It's mostly to do with how you drive it. If you hoon round expecting the same amount of grip as the dry, you'll end up dead, same with any car.

    I have a 2 seater so apparently my handling is a bit more touchy than a 2+2. But that's ok, i love my car and i've learnt it's limits and it's fine by me. It is possible to drive quite fast in the wet, it just takes practice and you don't wanna be a dick :p

    happy zedding

    NOTE: "When in doubt, power out" is NOT a reality and more often than not will get you into more trouble. If you start a slide, point the front wheels where you want to go and roll off the throttle - don't jump off it abruptly.

    nah i didn't mean keep pushing it further and further cos you'll just end up crashing into something at an even greater speed. I meant to slow down, but don't try to get out of the slide quickly in a panic. I did this a few times when i first switched to a rear wheel drive car and ended up in a mess. Like you said, backing off the throttle gently is the key :D

    ps: reading back on what i said earlier it kinda did look like i meant keep on the pedal. Sorry guys.

    my recent accident came down purely to driver error, lack of experience and a wet, mountain road. essentially i was comming down a mountain, at night, had been raining during the day and thought roads were dry but hit a wet patch in the middle of a switchback, back stepped out and before i knew it i was in a guard rail....quite a disturbing and humbling experience abuot my cars and my own limits.

    id say there are a few factors as to why zeds suddenly 'snap' oversteer
    1. DRIVER (even after going to this years qld skidpan day adn thinkign i could control my car well, it all changes when you loose it in less than perfect circumtances ie. off camber corner, sudden grip level changes etc.)
    2. Large rear tyres-many people (myself included) have aftermarket wheels and inevitably wider tyres, this means more grip yes, but also means when you lose grip it will be less controlable than with stock sized tyres because you have more speed. Also, fat tyres aqua-plane alot more than skinnier tyres, all in all wide tyres can become a liability more than an asset in the wet
    3. power- now tt boys think they're alone in this (and im sure this is breatly amplifyed, especially when turbos first kick in) but the na has alot of torque from low revs, so you need to be careful
    4. low center of gravity and rear camber setup which can be less than ideal at times

    anyway, this is all just my oppinion, hope this answers your question
