I bought Dave's set-up, and he suggested running the Motul 90PA: http://matrixsyntheticoils.com/store...n_oils.html#74

 

with a Nismo diff, run Motul PA90.

also: I was wondering (anyone can answer), when rearranging the clutch packs, does it matter where in the order you put the doubled up plates to lower the lock up?

ex:

AbAbAbAbAb < 100%
AbAbAAbbAb < 80%

for the 80, the matched AA, bb plates... could they be in the beginning (AAbbAbAbAb) or end (AbAbAbAAbb) and does it work the same way or does it alter the characteristics.

 

nice write up

 

hi!

i am thinking about improving my track times and so i stand between a new LSD or some new rimes ...

actually my car is a 350z MY2007 track model OEM rays (michelin pilot sport) and spacers (F: 40mm and R: 50mm) ... additional i improved my brembo brakes with drilled brembo rotors, ferodo ds2500, brake venting, stainless brake-hoses and ATE superblue ...

now there are two items, that i would rather buy ...

- os giken LSD OR
- work cr kai (9.5x18 offset 30 all around) and 265/35/18 semislick tires

which should i do next to improve my lap times ...

thanks for your feedback and excuse my bad english ;-)

LSD, LSD, LSD, LSD, LSD, LSD! Did I say LSD? It will do far more for your track times then a set of wheels. OS Giken is a great choice and is what I'm running in my 350Z. Find a local dealer to save on shipping or if that doesn't work out I have some contacts at the US OS Giken distributor.

thank you guys ... is the factory lsd really such a crap

 

the argument could be made... what LSD?

 

LSD without any doubt.

btw.. which track there? A1? Rijeka? Nurburgring?

 

NOS = Nordschleife (at the Nurburgring) ... http://de.wikipedia.org/wiki/Nordschleife
Pannonia Ring (Hungary) ... http://www.rennstrecken.tv/strecke/pannoniaring/
A1 Spielberg (Austria) ... http://de.wikipedia.org/wiki/A1-Ring

 

The factory viscous LSD is fine for a street driven car. Nice, quiet, and comfy. But its Scheiße on a track.

 

Let me reaffirm. LSD LSD LSD LSD.

I have some nice SSRs and now I'm aching for a good LSD.

The Giken gets a lot of good reviews from across the spectrum (Miata to TT RX7, etc), and that's what I'm going with on recommendation from Beta and a few others on here....once I can save up the $1,400 or so, that is.

Still, it'll be well worth it. You won't be able to use the extra traction of those wheels/tires for anything but braking and cornering until you replace the crappy OEM LSD. Not that that won't make you faster; but the LSD will make you faster no matter what wheels/tires you're running.

 

I am coming to Austria in December, we should take your car to nurburgring or something.

and by we, I mean you should let me drive it.

 

No smiley face, no nothin - not even a "please."

 

he's Austrian right? he'll get the joke without them.

but for everyone else:

lol!

 

NOS in december ... in that case i need a 4wheeldrive and not a LSD

so guys ... i talked to adam of z1auto ... and tomorrow i will order the os giken LSD ...

looking for a limited slip (my base model isn't cuttin' it). Who has experience with an aftermarket LSD on the track? Complaints? Suggestions as to what to stay away from?

 

You really should search this forum. Lots of posts and lots of advice here over the years regarding the various LSDs available for the Z33.

And to add you can do a advanced search limited to this section.

 

how easy is it to adjust the locking on the different limited slips? is it something one can do in between track sessions?
