are any of the other sedan drivers out there experiencing peg leg syndrome? because i swear i am just spinning one tire when i turn of VDC. do they make lockers or limited slips for our cars? i figured since the g35 has traction control they dont need to lock up the rear end. correct me if im wrong.

 

the 05/06 sport package models bring a viscous LSD

 

are you spinning both tires when you VDC is off?

 

Traction control is only going to help you gain traction on the one that is slipping by limiting the power to it.
You need a LSD if you want both wheels is spin evenly.

 

Traction control (VDC) stops wheels from spinning. This keeps you from spinning out of control or and gelps traction in the wet/snow. A LSD (limited slip differential) sends power to both rear wheels when one tire slips. This is good for traction off the line but bad in turns where the rearend can slip out in an instant. All G35's have traction control but only sport models get the LSD.

 

i have a 2003.5 6pd sedan, it came with sport suspension do i have lsd?

 

Not sure on yours but I don't think so. As stated above, I think this only came as part of the sports suspension in 05/06 (someone can correct me if I am wrong).

I just know that I have it on my 05.

 

I have an oem lsd on my 04 6MT sport.

 

I believe 04 is the first year.

 

How about sport packaged '04 G_sedan with 5AT, does she have LSD too? Changing my rear diff fluid soon.

 

Breakdown of oem VLSD fitment G35 sedans, all production

03 AT with or without sport suspension: NO
03 MT: NO (has sport suspension standard of course)

04 AT: with or without sport suspension: NO
04 MT: Yes

05/06 AT with sport suspension: Yes
05/06 AT without sport suspension: No
05/06 MT: Yes

 

Wondering where you got this info from, do you know of any ID's stamped on the diff to tell?

 

It should be obvious if you have it or not. Stomp the gas and count the stripes.

 

My 03 5AT non-lsd has no problems laying two perfect stripes of rubber. With 50% of the weight over the rear axle, the tires will usually plant evenly. Now in a tight WOT turn, the non-lsd car will be prone to lighting up the inside tire somewhat and this is where the lsd works it's magic. However, keep in mind the OEM lsd units aren't that great and are viscous in operation. That means slip has to occur in order for the viscous fluid to warm up and engage the lsd clutch packs. This takes time therefore the lsd will still exhibit some "peg-legging". Also, these are "limited" slip units and DO NOT split torque evenly across the axles. The clutches, though engaged, will still slip and I believe under full operation, the Nissan VLSD are only able to direct 20% of the power to the slipping wheel hence the name "limited slip" differential. These LSDs will not spilt torque 50/50. Only a true locker differential can do that and if you had that, you wouldn't be able to turn to well

 

He,he. I tried that once with an old 1/2 ton big block chevy truck. It is interesting to squeal the tires just turning corners under normal speeds.
