I'm building my car for the curves,not straight line power..I've looked at all kinds and i just havent had anything jump out at me..any sugestions?

 

Quaiffe!!! FTW!!

Here, read my old write-up:

I had the quaiffe in my celica.I wasnt sure if there was something better for the Z,But since you share my driving style.I'll gladly take your opinion!
thanks man

 

I have the nismo in mine. And like everyone says its poppy and clunky. I want to save for a quaife now dammit.

 

Here's a list of more handle-***** mods you should consider:

- Adjustable Coilovers (must have for corner balancing)
- Underbrace (GT Spec/Tanabe, I'd suggest Tanabe though)
- Tie-Bars (GT Spec)
- Solid Diff mounts (SPL)
- Solid rear-subframe mount (SPL)
- Solid End-Links (SPL - to set the pre-load on the sway bars and helps corner balancing)
- Fender Braces (Sunline has the only set I know of. A set is being mailed in to me within the next weeks and I'll be sure to write a review on this one as well)
- Roll Cage (Greatly stiffens up your chasis!)
- Weight reduction! (However, I added a 70lb system in the rear of my car and I actually handled better with all that weight holding down the back-end, LoL)
- Last and last for a reason: CORNER BALANCING!!! (cannot stress this enough!) Ferrari of Washington does this and Ptuning will soon be able to offer this service

I think everything else you already have though so you should be good to go!

 

Quaiffe is the only gear-driven LSD available for the Z which makes no pop and clunk noises. HKS has a gf: this mod has the "GF Friendly stamp of Approval"

Other LSD's I've looked into sound like your car is breaking and our stock VLSD is crap.

 

Yea haha its so embarrassing when I go into a parking lot and its popping and making all this noise. But do I love it in the canyon and streets. Its a real nice lsd. I have to try the motul fluid. They say it quiets it down a bit.

 

Motul 75w90 gear oil FTW!

I run Progress adjustable sway bars, Gt-spec front and rear tie bars, adjustable camber arms, Project Kics 20mm rear spacers.

The Progress sways are pretty nice and I love the adjustability.

Gt spec tie bars install in a matter of minutes and are noticable right away.

The project kics spacers are more for looks but widen the wheelbase a little, call me crazy but I can feel a slight diffrence (especially when I bomb exit 77 at 110mph)

Camber and toe arms help get you alligned properly, go with camber arms that use busings as the heim joint type tend to creak under lots of stress and daily driving.

 

Carbonetics Carbon LSD-Ive driven one it handles nice and is smooth and quiet in its operation. If I still had the 3.5FD Id have one....

 

I am thinking about buying the quaife. Was a straight drop in for the stock vlsd pumpkin or did you need to get new output shafts.

 

It drops straight into the base pumpkin only

 

Ahh ok. So I need one new base output shaft then.

 

I must politely disagree.
My Carbonetics 1.5 way LSD is awesome and does not make any noise under normal driving. The ONLY time I have ever had an issue is when doing the tail of the dragon and that was expected because were tearing through chicanes at 30 - 40mph... Without a doubt definitely a difference in keeping all those wheels working for you. I have even taken the 3.3 pumpkin back out (after the Salt Flats run) to put this back in my car.

But as others have said the Quaife is a awesome unit to.
Just my $0.02 of course.

 

good thing i kept my base final drive assembly. once i get the quaife then it is easy and cheap to install

 

I drove a z with the rtune lsd..itsa nice!

 

Does anyone know if a 3.357 ring gear can be made to work with either the ATS carbon or the Quaife?

Quaife is apparently no longer selling for the 3.3 rear diff any longer...
