Just curious how many FI guys are running their stock VLSD (who have one)

My 2006 G35 came with the VLSD stock, and I'm wondering if I should start saving up for a new dif...

I have a GTM stage 2 kit and just dyno'd at 515/510. How many people have grenaded their stock dif?

 

SP uses stock rear end at 1250whp. YOu have a long way to go before you have to worry about blowing it up. Now getting one for better traction is a reasonable goal.

 

Stock one here with 688ft/lbs @ high boost.

Ive driven Carbonetics diffs and didnt think it was as much of a diff as its made out to be, in other words I wasnt impressed.

 

stock vlsd here...and just made 801rwhp (don't know tq yet...didn't have tach reading).

The rear mounting bolt on the cover is the weak point not the diff itself.

How do I know if I have a VLSD? I just picked up an 03 Track.

 

I know 240 guys are opening the diffs and adding an additional shim between the sides, that makes it 1.5 way lock , and they get better traction, not too sure about how long it will last you , i'm about to get on this project myself

 

Every model other than the base has an LSD

The fun way to get the answer would be a redline clutch dump and observe the tracks!

Wating for thread on broken Axles......

or if you jacked the rear up and spun the tires. they should go opposite direction if you have a lsd.

redline dump is probably more accurate though

 

My 6speed street car went low 9's on the stock LSD. Our auto drag car made many 8 second passes on stock dif without fail. I wouldn't worry too much about the dif

I would suggest using an IP dif brace if you plan on racing or use an aggressive-engaging clutch.

 

My dif makes an awful sound and kick when changing gears driving hard

More stuff to buy

 

is there a weak point in the rear end that we would need to worry about when dragging the car..... in other words do i have to worry about running my two step on slicks and dumping the clutch at about 7 psi..... what are necessary upgrades to not have it snap something .... not to knowledgeable on the rear end!

 

Worry about slicks? I wouldnt enough to not run them. When racing you WILL eventually break $hit, its a reality you have to accept.

I can tell you however if you DUMP the clutch as opposed to preloading and doing a quick slip or launching your chances of breaking are significantly higher.

 

The dif should be fine with the above-noted brace, as should the stock driveshaft. The axles on the other hand, definitely need to be upgraded. I would suggest DSS Pro axles. These are a little more expensive than DSS Stage 5 axles, but come assembled with upgraded ends, whereas the Stage 5's require swapping your stock inner hubs onto the DSS Stg5 axles.

DSS Pro:


DSS Stage 5:

 

+1 , I agree.

 

the diff gears are fine...the mounting isn't great...look at the diff braces (IP and SP both offer them).

Next would be the CV joints and Halfshafts.

EDIT- Darnit' Hal...beat me on the clicks lol

 

also running slicks is WAAY easier on the car then DR's

Funny because in the Supra forums, they are adamantly against DR's on 6speed cars, but here DRs are the norm.

 

They do tend to have a bigger "hit" of power in the big singles that makes it hard for the tires to handle....we have a little more tq to help make things a little more linear. I'm sure everyone here will eventually learn that slicks are the only way to lay power down eventually.

Thanks for all the input! I have a lot of friends that drift and are always destroying stuff.. lol makes a guy wonder

 

I completely agree with breaking sh*t, it will happen and makes sense not to dump it completely.... I know launching hard will have its wear and tear. thanks

thanks for the info i will look into buying this after the build is done ....




sorry OP i took the opportunity to ask....
