viscous slip differential
 
is it worth getting sports package on the car due to the viscous slip differential it comes with? is it a big improvement or what u guys think?

The LSD was a factor in my choice. So to me....yes.

the sport package offers big wheels, brakes, sycrorev, and an lsd. Try getting all that for less that what the sport package upgrade costs. Personally, yes I think it's better, I've had cars without it and I hated when only one wheel spun out.

the Viscous LSD, no, everything else, great value. Viscous LSD's are garbage, overheat quickly and lose effectiveness, there have been alot of problems with the stock LSD, check out the track threads.

And Quote:
"Viscous LSDs are less efficient than mechanical types, that is, they "lose" some power. They do not stand up well to abuse. In particular, any sustained load which overheats the silicone results in sudden permanent loss of the differential effect.[5] They do have the virtue of failing gracefully, reverting to semi-open differential behaviour. Typically a visco-differential that has covered 60,000 miles (97,000 km) or more will be functioning largely as an open differential; this is a known weakness of the original Mazda MX-5 (a.k.a. Miata) sports car. The silicone oil is factory sealed in a separate chamber from the gear oil surrounding the rest of the differential. This is not serviceable and when the differential's behaviour deteriorates, the VLSD centre is replaced."

In closing, dont buy it for the LSD, buy it for Synchro Rev Match/Wheels, etc.
Best LSD's in my opinion are the 1.5 way Carbonetics.

For normal street use, the LSD is fine. If you want a track car, then the diff is one of many required upgrades.

I don't think the guy is tracking his car. For the street, the viscous LSD is a fantastic item. The whole sport pkg is a steal, imo.

Sold a house in Brooklyn, got the asking price in cash. Hence the new car.

Woof, we derailed this thread. Well in this neighborhood, the average is at least that. It's become like Little Russia...huge influx of Orthodox Hasidim, you know, the guys who wear black hats and have lots of curls...and they have the $$$$$$$$$$$$$. AND, they have to walk to the temples on Saturday, they can't drive, and this house is like 2 blocks away from their temple :icon17:

Back to topic :ugh2:

I guess one way to find out if your VLSD has worn out, would be to dump the clutch and do a burnout (6MT), or stomp the gas (7AT), and observe if you have 1 wheel or 2 wheels leaving rubber...

And if your LSD isn't burned out already mebbe you'll do the deed! Sorry Kann, couldn't resist. :tiphat:

zellsexy 11-24-2009 07:36 PM

so all in all, the sports package is worth it? also what if i decide the 7at? then the syncro rev match wouldnt matter right? or does it affect 7at still? im just worried if i get 6mt i wont be able to drive it to the ful potential cuz i dont have alot of mt experience ><
