For the street driving I do the factory one hooks up nicely.

 

It's a known fact. VDC is never completely disengaged.

Drive aggressively with VDC off, notice the slip light come on? Feel the power drop as the light is glowing?

 

is the LSD a direct swap into our cars? (i have the 7 a/t) without changing the gears?
anyone know how many hours approx of labor for the job?

 

Update.... The shop got a late start on the install. Ran into a snag as well . It's not a direct drop in. Cars that have a vlsd need to have one of the stub axels shortened by 1.7 inches. You would think quaife would have instructions on this. They do not . We had to search the Internet to find that info. Other than that everything else is fine. Car won't be on the road until Tuesday due to the delay and holiday. Will let u peeps know more next week..

 

They should have told you about that. When I was talking to z1 about this diff they asked if I had a factory LSD just for this reason. Its a $150-200 from them Iirc.

 

sounds like a very interesting project.. can't wait to hear ur feedback on it!

of course, a video with 0-60 launch and a 70mph cruise would be a great compliment to this thread

 

No, actually I haven't really noticed the power drop; neither at the strip nor during drunken drifting sessions.

But I'll pay closer attention now ...

 

I've had mine activate even after turning it off on multiple occasions.

 

But do you feel it actually pulling power - or just see the "slip" light?

I've seen the light, but I can't say I've felt it pull power like it does with VDC on - which is obviously noticeable.

 

By activate I meant feel it kick in. It's not as brutal but it's very noticeable.

 

Did you have to do shimming when you reinstalled? I am fairly new to this area of upgrades and dont know much about the rear diff. I know I don thave the VLSD and the install looks easy but i keep hearing about shimming but no one shows or talks about it.

 

Varies from set to set and no two are the same.

 

^^^ huh?

 

No two vehicles are built the same and no two LSD's are built the same and no two ring and pinions are built the same. I got lucky and my car shimmed up perfectly the first time with the 4.08s and factory LSD. Your's might have to be shimmed multiple times to get the proper gear mesh. It's best to let somebody who is familiar with rear ends set them up as it can be quite tedious and time consuming.

 

^+10 If the gears aren't set up right, they can "howl or whine"... you might too a few hours of listening to them.

If anyone can, before and after 0-60's or 1/4 miles would be good to know.
