Z1 LSD compared to others

Jinxx · 03-16-2020, 02:50 PM

Looking for info of the Z1 lsd vs quiafe and wavetrak....I cant seem to find much for comparison ....or really any info on lsd. When do people with boosted Zs switch out the lsd and when are signs of the VLSD being worn out.

For those wondering, this is probably the one he is talking about. Both it and the Quaife will operate similarly.

Neither them nor Quaife go into torque bias ratios, but I'm going to guess they are both somewhere between 2:1 to 3:1.

A good time to upgrade LSDs is when you are getting noticeable single wheel spin from a launch or spinning just your inside tire and not putting power to the outside one when powering out of a turn.

The Wavetrac acts very similarly to the Quaife with the exception that it will lock with one wheel in the air, whereas the Quaife will not.

Don't know anything about the Z1 diff except that I wouldn't buy one.

Yes that is the one .... not sure if I have one tire spinning or just losing traction to both ...tires are Michelin PSS 305/35/19 ..I will be switching to nitto NT05 but with 45k miles on the VLSD thought it might need replacing as well

Anything is better than the factory VLSD. It sucks.

The oem vlsd will open up when hot. When fresh, I could do about 30 minutes on the track before it got hot. With wear and tear. I was down to 10 minutes before it would give up the ghost.

The Quaife, WaveTrac, TruTrac, and the new Z1 are gear driven. If you jack up one wheel. The Quaife will open up. The Wavetrac will not. Don't know about the Z1 unit. The TruTrac doesn't fit the Z. Plus side on these is that you can use regular gear lube.

Clutch type like OS Giken, Cusco etc are tunable. You can set them up 1 way, 1.5 way, and 2 way. Plus you can change the amount of lock up. I have an OS Giken set up 1.5 way and 80% lock. The down side is that you have to use gear lube with the LSD additive. The OS Giken needs it's own lube. 75w-280. Which is $70.00 a liter.

I don't know about Z1 LSD, most likely it is a rebranded lsd. Helical is good for street and track, didn't use one on my Z but I liked it on my srt 392 (factory equipped).

I get the oil from Japan, $33 per liter + shipping. It is 80w250.

Yep, plus the Z1 diff cover. 3 liters to do a lube change. $210.00.

OptionZero · 03-16-2020, 06:55 PM

does that cover really do anything? If you need a cooler anyways . . .

Noop, waste of money. Just get a cooler from MA-Motorsports. LOL

Jinxx · 03-16-2020, 09:09 PM

Will normal driving heat up the vlsd to where it won’t lock ....or do you need to be launching or tracking to heat it up ..trying to guess the were on mine ...only been to the drag strip once and the rest would be mild launches ...I would assume even a rolling launch would wear it down as well

The biggest problem with the VLSD on a boosted car is it is very unpredictable. It can get you in a heap of trouble quick. Go ahead and do a Z1, Wavetrac, or an OS Giken. You will thank us later. Best money you will ever spend.

Hotrodz · 03-16-2020, 10:09 PM

I have been running a Wavetrac for quite a while and I not had any issues and it has performed as advertised. One of the pluses with Wavetrac is their lifetime warranty. The warranty is also transferable if you decide to sell it or it with the car.

The 3 I have been considering are the quaife..wavetrac and the Z1. Not sure about quality of Z1 ...they say it’s not a rebranded item but I don’t think they have a manufacturing department .. I wasn’t impressed with their road race clutch kit and had to replace it after 5k miles
