Hi everyone, i'm new in this forum.
sorry if this topic was brought up again..
the biggest question i want to ask is that..

is it possible to install VDC on a base model that doesn't come with it in the first place?
if not, is there anything that does the same thing to replace it? i've read about LSD but i still know so little. if it is possible to install VDC, what is the price range?

thanks in advance

 

No. Don't even bother. To this day, nobody has figured out how to add cruise control to a base. A VDC install would probably be 10X more complicated.

VDC is a tightly integrated system, not something you'd find in the aftermarket.

 

thanks soo much for the information,
but how about LSD? is it possible to install?
i have read many replies on this forum, all are soo useful,
but sometimes i think i don't need it because i know what i am or not capable of.
but sometimes i think i should go safe just in case, is there anything that is equivalent to it just for safety?

 

Welcome. With money its possible to do anything. But the cost is prohibitive.

 

As far as I know, just installing an LSD in place of your base rear diff. shouldn't be a problem at all, it's just a mechanical part.

 

thanks again~
so installing the LSD should do almost the same job as traction control right?
sorry.. i don't understand it really well.
but what is the price range for the LSD?
what is the function really.. really similar to traction control TCS for the Z right?

 

I have a base 05'. The LSD simply distributes power to the two rear wheels based on the relationship between them.

The open diff our cars came with sends power to the path of least resistance, so it actually sends power to tire that has the least traction.

The stock VLSD in all the other Z's reacts to differing wheel speed. When one tire spins too much faster than the other, the goo inside the LSD thickens and forces both wheels to go about the same speed. (So when one tire looses traction it starts going much faster than the other and the VLSD "locks" and gives about 50/50 power to the rear wheels.

I believe that clutch-type LSD's react to differing wheel speed also, but they use clutches instead of viscous goo and can be adjusted, on install, to "lock" sooner or later in the traction-loss equation. They can also handle more power than the stock VLSD.

The Quaife LSD (this is the one I run) uses gears to send power to the tire with the most resistance. It "transfers power from the wheel that slips, to the wheel that grips." (Like the old Subaru commercials, only we are talking about two wheels instead of four) The Quaife can actually bias more power to the side with the traction where the other types can only "lock" into a near 50/50 power split.

The TCS system uses sensors to detect a loss of traction and controls the brakes, individually, and the throttle to try and regain traction. But it won't help you go faster. If you want traction to help you go faster, (i.e. power out of turns) a LSD is the right tool for the job.

Prices for LSD's range from a few hundred dollars for a used stock "pumpkin", (VLSD inside the housing, getting the whole pumpkin assembly just makes the install easier), up to 1300-1500 for the Quaife LSD. Clutch types tend to fall in the middle of the price range.

 

thanks "Z1NONLY" for all the information~
i kind of get the picture now~
so you are saying even the base model like my 04 350Z base has the VLSD? that does:

"reacts to differing wheel speed. When one tire spins too much faster than the other, the goo inside the LSD thickens and forces both wheels to go about the same speed. (So when one tire looses traction it starts going much faster than the other and the VLSD "locks" and gives about 50/50 power to the rear wheels."

?

 

Base Z's have open differentials, the are not limited slip, or LSD's. All Z's except the base have VLSD's.

I got an aftermarket LSD for my base 05 Z. (Quaife)

Sorry my other post wasn't clear.

 

Afraid not. To simplify:

TCS/VDC: Electronic system that cuts engine power when it detects
tire slippage. Does not come on a base Z, cannot be installed.

LSD: Type of differential that locks the rear wheels together when one loses traction. Does not come on a base Z either [you have an open differential], but CAN be installed.

They accomplish similar goals, but not the same thing at all, and base models come with neither.

 

thanks guys~
thanks sooo much for the data
i still love my Z, it's lighest of them all besides i know my capability.. i don't go off the limits
