After doing some research I couldn't find an answer pertaining to the 07-08 350z with the HR. I was just curious if all models had LSD or if the base model did not have the LSD like in previous years. I'm currently looking into getting an 07-08 with the HR, however I really want the LSD. Also how can you tell the difference between a base model and the others? Thanks guys.

 

Base model doesn't.. If u have steering wheel controls (audio and cruise), it's got LSD.

 

Thanks, thats the answer I was looking for.

 

The factory lsd is ****.

 

If you don't care about cruise control. Save the $ get a base model and buy an aftermarket LSD.

The Bose Radio sucks just as much as the base stereo so your not getting much for your $ buying a touring model or such.

I went with a Solar Orange 07 Base (paid $16k flat, with 39k miles). Had to replace the Clutch CSC (Concentric Slave Cylinder) about 3 weeks after i bought it. Replaced the stereo and front speakers immediately b/c the OEM are garbage.

I've got a Quaife ATB on the way and already have 4.08 gears in a spare pumpkin waiting.

In short i've got about $18,000 for 07 Base with a stereo better then the BOSE setup, a Quaife diff (not an LSD but ALOT better then the OEM VLSD), and 4.08 gears.

All depends on your needs for the car but i'm going for bare essentials and speed parts.

 

Quaife is an LSD, just a gear-type (Torsen), rather than a clutch-type LSD.

Quick overview of commonly available Diffs:

Open - has peg-legging when you overwhelm one tire, most stable directionally, can put least power down. Base models have this.

Viscous LSD - Uses a fluid that becomes more viscous (gel-like rather than watery) when it heats up. Non-base models have this. Only locks about 20% or so, and is reactive rather than proactive (requires wheelspin to lock up). Also, the fluid breaks down eventually. Functions as a 2-way LSD.

Quaife/Torsen LSD - Uses a series of worm gears to provide locking. Generally can provide up to 75% or so locking. Proactive. However, due to design, if one wheel breaks loose, it functions as open diff. Functions as 2-way LSD.

Clutch-type - Uses a clutch pack to provide locking. Can provide up to 98% or so locking. Proactive. Needs occasional maintenance, and too-high locking can cause issues in slow speed situations. Works even in zero traction conditions. Depending on exact design, can function as 1, 1.5 or 2-way LSD. Generally set up as 1.5 or 2-way. Generally the most common and most "tunable" LSD type.

Spool - both sides are locked together all the time by design. Drifters and drag racers seem to like this. Turning requires the inside tire to slip, causing lots of tire wear and general crappy handling.

 

Not to nit pick but the Quaife / torsen rear ends are not Limited Slip Differentials (LSD).

Technically they are an Automatic Torque Biasing (ATB) differential, not limited slip. That's why if one wheel has zero reistance torque it acts as an open diff.

Eitherway open and vlsd sucks

 

well i want cruise control i do 99% highway driving and i live off cruise. but after finding out its vlsd ill probably be throwing a quaife in it anyways. i mean, the car is going to be a daily driver, but i want to get into "casual" drifting. lol

 

What would be most suitable for roadcourse/street. I have an enthusiast model. Never thought about aftermarket LSDs

 

i prefer 1.5 for all around

 

Quaiffe or clutch type would be the one you want.

 

from what i've researched all around the forums, web, and vendors, everyone recommends 1.5way clutch type for street/track and 2way for track dedicated and some skills to

 

2way for drift.

 

Thanks, I'll definately look into it. Any other specific companies that come to mind? ie cusco, kaaz etc?

 

Just got my QDF11L Quaife Diff from THMotorsports for $959 with 3 day Fedex.

They are the cheapest guys around for the Quaife diff, and have a 4% off coupon code running right now on the home page.

 

I've been doing some LSD research, but the purchase is going to be delayed because I'll be needing new tires again soon...

The OS Giken seems to be the hot ticket clutch type LSD these days, particularly if you get the clutch plates treated.

 

i have a kaaz 2 way and love it, kinda noisy but locks like a ****

 

Thanks for the heads-up on that, I've been eyeing this diff myself and that was enough for me to finally bite the bullet

 

If your not drifting and stuff why would you want tires to lock up at all?
Would this help handling in a corner if you start to slip or...?

 

you don't..
