I've not observed it, but I wonder if one of the rear wheels isn't moving when you have to wheel kicked over all the way.

It's crazy tight.

That, combined with the sharp steering...coming from Ford's and Chevy's to this - yeah...it's different :)

I think what threw me a bit too was that the tires bit down unexpectedly too - but, hey, I won't know. If I do it again, I have more knowledge about how the car reacts to driver input now than I did before last night.

we have a locking diff?:confused:

No offense to those who will buy one of those - but I'd buy just about anything else before buying one of those.

That rear window :icon14:

Sport package has something like a locking differential...viscous something...

All I know is it's easy as hell to slingshot the rear end - soapy tires or not ;)

Apparently, I found a limit relating to the amount of available traction, and my expectations of what the input I was doing with the car, and the output it gave me.

"Lesson Learned"


The place to learn the limits of a car is at a Driver's Event, not a public street. Controlled, safe environment where people are prepared for the limit to be crossed. The masses on a public road are not expecting a car near them to have a tank slapper. They do not know how to react and you could hurt others...

I am getting too old and too out of shape to keep climbing onto pedistals.

It was 11:00PM out in the country with absolutely no traffic around for at least a mile in every direction. While it is/was a public street, but it was also pretty desolate.

That said, I absolutely agree with you...

Get over yourself.

Yes, you actually nailed it. It is in fact my personal responsibility on the internet to flame people whom I view as being "l3ss sup3r $kiLl3d" than I. You just keep giving me ammo and I thank you for that, however I think I'm just saying what everyone else is thinking without being coy.

I love this forum for all the info and good folks in it, but its a joint effort to keep at least a slight hint of substance in the threads. AK can't yell at you because you've done nothing wrong, but I have no affiliation with the forums other than being a member and that gives me the right to say whats on my mind. There's been a huge (and growing) number of ridiculous nonsensical threads popping up lately and I'm frankly just tired of sifting through the crap to get to the worthwhile ones.

I dont mean to speak for anybody else, but I have a feeling that I am, when I say that nobody cares about how you almost crashed your car leaving a deserted car wash in the middle of the night. I wasn't going to jump in until you said your "quick reflexes and experience" are what saved you, when in fact it was the lack-there-of that got you into that mess. The only thing that saved you was space, luck and low speed. Try those shennanigans at pace and I will be the first in line for the part out.

I'm not singling you out because I dont like you... I dont know you, you may be a cool guy, but people please stop posting junk , no one cares... about who called you out in a parking lot or how many SRT-4's want to race you on a daily basis.

BTW: Are we allowed to call dibs on part outs before they happen? if so DIBS!

Next time just tell everyone you were doing the " Finish Flick ".

RCZ - you have some really informative posts, and I really appreciate a lot of your passion about vehicles and driving, but from an outside perspective, you're way out of line here.

If you don't like wasting time, don't post (repeatedly) about a timewasting thread. The internet is a timewaster, in case you haven't noticed, and internet skillls *always* involve separating the wheat from the chaff. Personally, what's hard for me to read is someone drilling something when they have no idea where they're coming from.

And sorry to say it, but you're projecting way too much onto this guy. He didn't say he was some jackass street-racer, nor was he crowing about his crazzzy exploits. He just had a moment where he jumped on the throttle on soapy tires and the car got out of hand - and he shared about it on a board where people share about car stuff. If reading about it isn't your cup of tea, fine - skip to the next thread. I'll bet that any person on here doesn't care about at least 50% of the threads on here (including threads on how to set up their car for the track). That's because people are different.

From the outside, you're the one who comes across as a showoff, trying to act like you have never made a mistake on the street, or talking down to them about attending driving classes (which, again, is a way for you to emphasize your mad skillz).

And I hate to tell you, but it actually isn't your responsibility to sanitize the boards for everyone else. Some people aren't on here for the same reasons you are. I have taken driving classes, and I do try to keep it safe on the street, but I could totally see being stoked on my clean wheels, juicing the throttle, and getting a bit sideways. I'd like to assume that wouldn't be 45 degrees sideways, but then I'm not going to judge a street or a situation that I don't have a clue about.

Anyway, I'm sure I'll get flamed back. I just think you seem to view yourself as some kind of cop trying to check other people, and I think you might want to check yourself on this one and apologize.

That's pretty funny.

I did a 900 degree spin in a Suzuki Samurai 20 years ago. It was on an off ramp to the Capital Beltway and completely unintentional. It scared the hell out of me.

FricFrac 07-02-2009 06:25 PM

Since I have no experience on the track slot me under the "you suck hard you pathetic excuse for a driver" category before the flaming begins.... but I was surprised when I tried to get the rear end loose how quickly the rear bite came back and the car felt quite planted compared to doing the same thing with my 280ZX (only had 225s on the rear in comparison to 275s)....

Here's a good explanation from a G35 forum:

Quote:

VLSD = viscous limited slip diff

The stock viscous limited slip works by immersing a series of round plates, alternately attached to an axle or the differential housing, in a fancy viscous goo. When you go around a corner, the outer wheel will turn faster than the inner wheel, but because the differential housing itself is going at a speed halfway between the two wheels, the differential housing sees the outer wheel turning forward and the inner wheel turning backward.

The plates can be stacked various ways, but let's assume that on each side of the differential there are eight plates, with half of them attached to the axle, and the other half attached to the differential. Call the axle plates "A" and the differential plates "D", and they will stack up like DADADADA.

The plates in a viscous limited slip don't actually touch each other. Instead, they are separated by a thin film of this viscous goo. When you go around a corner, and the A and D plates start turning at different speeds, the goo trapped between them heats up. Some chemist somewhere figured out how to make a magic fluid that expands and thickens under this shear load, making it more difficult for the plates to go different speeds.

While the fluid tries to lock the plates together, the tires try to rip them apart. At low speeds and gentle turns, the fluid doesn't get thickened much and the tires win. Boot it and try to spin one tire and the plates suddenly are going dramatically different speeds. The fluid thickens just as dramatically and, with the stock tires, the fluid wins, locking both rear tires together and letting you have your glory slide. A little less throttle and you have the smooth, seamless acceleration Nissan engineers had in mind. If you have really sticky tires, though, the tires win, and the long, gooey molecules of the stock diff's viscous snot get sheared into smaller, less thermo-reactive visco-thickening stuff; stuff that would make that mysterious chemist blush with embarrassment.

FricFrac 07-02-2009 09:06 PM

....and that's how it (sorta) works in our R/C vehicles. That being said we can change the viscosity of the fluid based on the type of racing/driving size of the vehicle, etc. Can we change the diff fluid in our car for a more agressive driving style?

Really good info...

Thanks!


That said, I know with oil sheering is what damages it's ability to function - I also seem to remember reading about the viscous stuff needing to be replaced every so many miles because it gets weaker with time.

Maybe I read it in the manual - lol, I don't remember...but it does have me curious if we'll have issues in the long term.
