370Z Factory LSD: This thing is worse than I remembered

Sharif@Forged · 02-07-2010, 10:00 PM

Admittedly, it's been a while since I've driven a car hard, that didn't have a mechanical aftermarket locking style LSD such as Carbonetic, OS Giken, Cusco, and others.

I took my first obligatory mountain cruise with my 370Z today, and immediately discovered just how horrible this LSD is for any type of performance use. Keep in mind, I wasn't pushing the car that hard, since this is a public road but it's performance left a lot to be desired. It felt one small step better than an open diff. On tight corners, on power exit the inside wheel just spun freely and would catch and grab in a horrible way.

Next on my shopping list is an LSD, because this car will not be fun on a road course. Our Time Attack 370Z has a Cabonetic 1.5 way and is brilliant. I might try the OSG on my car and see how it compares to the Carbonetic.

I am intersted to here everyone else opinion on the factory LSD.

who has already made lsds for our cars? I have the AT and Im noy sure if any are available.

For a street car, I have no issues with the LSD. You are spoiled with the GT-R

Even on mountain twisties at 6/10th pace the difference is very noticable. If you rarely take the car to the twisties, then I am sure the OEM diff is fine for street use.

I always take the car to the twisties. That's why I bought it. Seriously, I'm not having any issues at all, I'm not some n00b, I'm race-trained in Formula Fords.

I have no doubt the LSDs mentioned above are much better than the viscous oem unit. But I think the oem LSD is quite adequate for street use. No mountain twisties around these parts, but lots of twisties, elevation changes and very challenging old New England roads. In fact, the most impressive thing about this car is it's predictability when exiting a corner at speed. Besides I like a little wheelspin, it's challenging and fun.

Without a percentage number e.g 40% lock capacity the compare discussion is use less.

http://en.wikipedia.org/wiki/Limited_slip_differential

The technology of differentials and LSDs

Making things worser than they are should not sell other things better

P.S: a VLSD has normaly a curve delta wheelspin to torque % transferred to the otherside

Sources will help to compare

Yeah, it does add a little excitement.

It depends a lot on how you drive the car. I drive mine extremely hard on twisties in the mountains, but I am not driving like on a race track where it's full brakes into the corner and full power out, for me the challenge and fun is carrying corner speed, not full g's into or out of the corner. In between the corners (if there is any) I am enjoying the view. At the limit of cornering force, you'd be hitting the traction control with more than neutral throttle anyway (and I would never do TC off on tricky unpredictable mountain roads, often damp and with moss). So I would not ever likely spin up in inside wheel. Also doesn't our car brake the inside wheel if it spins anyway? Have fun you maniacs.

I think it's OK.

370z4Steve · 02-07-2010, 11:37 PM

well..even a cayman has an open diff...

Xan · 02-07-2010, 11:43 PM

If you weren't pushing it hard, why did you need the LSD?

Did you change your rear strut/sway?

B1nks · 02-07-2010, 11:51 PM

I REALLY want the OSG LSD and have an open diff and I miss the VLSD from the factory it's so bad haha. Hopefully the OSG will satisfy my needs since it's my next mod then sways.

corner3garage · 02-07-2010, 11:54 PM

Yeah I heard the in lift is pretty bad! lol good luck with the clutch type.

How is the NISMO lsd kit different from the stock LSD? I've been eyeing that.
