Clutch-Type LSD Review - Tomei 1.5-Way in a 370Z

[@maginext]

All other videos explain Limit Slip Differential mechanism only. Thank you for explaining use experience as well.

[@swanblake]

Just found this channel as I was thinking of upgrading my Vlsd in my 370Z. Amazing video on both the install and this review. Loved you showing how it works in the parking lot. Thank you for this!

[@sharpemang]

You have helped more people decide on products and installs than any other youtuber. Love the info you have!!!!

[@ivoke103]

Finally a man and a video to help me decide whether to upgrade the differential in the car. I go to track days 4-6 times a year, but basically I use the car on weekdays. Your video is very useful, thank you very much!

[@Rs38y]

So did you install the lsd? If so, which one?

[@VoodooBoot]

I now feel better about my Nismo Pro LSD diff. Thanks for the good video!

[@rayndooma5624]

Solid video my guy. All the info I needed about daily driving a 1.5-way LSD with occasional track use. Great job capturing the noises the LSD makes on slow, tight turns.

[@AlexChauJDM]

Awesome video. I'm trying to figure out what to get for my S14 and I think this made me decide on a 1.5 way for sure. Also, I watch movies at that cinemark at 4:50 all the time haha. Always great seeing local content creators.

[@30YearOldBunta]

Great video, with V8 torque in a open diff I know exactly what you mean about having to drive carefully through a corner. I drive this thing like a semi truck and sometimes I wish I could plant it properly because the rest of the car is somewhat stable.

[@oliveranic3537]

Thanks for the awesome explanation. I just got a FWD car with a Cusco 1.5 adjustable clutch type lsd. I have all the same noises and driving experience, thought it was broken.

[@roninmantis7584]

Love the graphics and explanations. I enjoy watching your build videos. Gives me an idea of how much work is involved in building my sport Z.

[@babloo1666]

you are a complete boss dude

[@ChaseMMD]

I thought I had a VLSD but learned later that i'm running a open diff and TBH that blew my mind. I'm running some PS4S tires and i'm thinking to myself "Wait so I have this much traction on a OPEN DIFF???!! So what happens when I go for something like a 1.5 Way Diff??" If you haven't tried them I'm running the base 09 model with 8 and 9 inch stock rims and running 235/45/18 and 275/40/18 and man even with the open diff the car is a blast! Can't wait to get this done in the future!

[@snakes5506]

Just what i needed to know about this type of diff, thanks man !

[@axelriet]

The noise is really dependent on the type of disks. Your diff may have metallic discs which are the most noisy. Sintered discs and carbon-lined discs also exist. Finally you must use a suitable oil, one with “LS” on the name such as Millers CRX LS 75W90 NT, or Castrol Syntrax Limited Slip 75W-90, assuming the diff oil is separate. These a long chain lubricants specially formulated for plated diffs and will help with the noise (but you cannot use LS oils in synchro boxes: the synchros don’t bite with those very slippery oils).

[@axelriet]

And I just learned about “Motorcraft additive friction modifier” - either add that to your regular diff oil, or check out one the the LS ones.

[@7eamGhast]

Really well put together video. Honestly the only review on a differential I've seen on a Z in KZbin. I'm just wondering why you didn't consider WaveTrac? Zero Maintenance, Zero Noise, No Extra tire ware, and LifeTime Warranty. I've never heard of one underperforming and I've never seen one that couldn't handle what was being put to it. I used one on my 500 WHP Evo9 MR, worked so well it was almost too good to be true. Got one for my 370 also, but haven't installed it yet, I'll link you when I do the install. Cheers Brother.

[@thecarizon504]

Mainly a price thing. I budgeted $1000 for the diff. Understandably there are better diffs out there but I have other projects in the pipeline I am trying to get to.

[@7eamGhast]

The Carizon That's cool, I completely understand!

[@freddybell8328]

​@@7eamGhast did you install it?

[@7eamGhast]

@@freddybell8328 not yet, I actually sold the Z but I still have all the parts. I have too many projects and. It enough time so I’m going to finish the Civic and RSX first and then my Silverado, then I’ll hunt for a 2010 40th anniversary Z to install all the build parts I have for it. Sorry to not be of any help.

[@TheOfficialWoof]

Beautiful explanation and review

[@vacoombs]

just came across this channel and im definitely going to subscribe.

[@hjom8733]

I had a kaaz, and everyone in a parking lot would look at me like my car was falling apart. I eventually swapped out to a wavetrac and love it

[@geeaye64]

Thanks for the review and explaining everything

[@PeterKnagge]

I got a KAAZ (SuperQ) 1.5 for my HiAce van. I found changing oil brands made the chatter go away.

[@thomasgonzalez5130]

What oil and additive combination made it go away?

[@boosted_brody5474]

Which oil?

[@on-site4094]

It’s a track diff you have to get use to the noise and extra maintenance if your going to use as a daily driver

[@thecarizon504]

It doesn't bother me all that much.

[@ramkhazen]

Thank you for this review.

[@hama_sardar370]

Great vedio keep it up

[@gleesmj]

Great video, very informative! Thanks

[@angrywargamer8836]

Some diffs offer differnt ramp angles and presets making the rear end much much more streetable

[@c2h6-e]

The lsd chatter is just a noise that we love but makes everyone else thinks your car is broken

[@VeneraSGF]

Will modifiers. Remove chatter and noise.

[@WarWizardProductions]

Hello. I am going to upgrade my differential as well coming from an open diff. I want to have the option of drifting sometimes but I don’t want to sacrifice drive ability too much like the clutch types. I was thinking about either a qualife or a Z1 street pro diff. Which one would you prefer to be better for me?

[@jennifertaber9827]

which did you go with?

[@yugu8988]

Great video! I just got my tomei 1.5 way installed on my Miata. Has the same issue as you stated. Did you try adding some friction modifier. Some say it will help a lot in terms of noise.

[@thecarizon504]

Not yet, that's something I plan to try at the next oil change. I'm over the sound at this point, doesn't bother me but causes bystanders to worry that the car is on it's last leg. 😂

[@stockboy6196]

Just subscribed because you actually explain things very well! Sweet 370 btw!

[@MichaelTonyp]

Great info love all 370z stuff

[@TheTravelingBunch]

you can just clutch in to stop tire wear in low speed turns

[@roberts8783]

i think you bought a race specification as tire marks would suggest that. what did you go for ?. i had a nismo 2 way back in 2005 and it wasnt that bad. but very noisy

[@newtypetommy]

my Cusco 1.5 way sounds like this in my ZZW30. I expected it but i hate it haha.

[@ZXXpilot]

Full spool for life! #RIPtires

[@memphis370z]

What other diffs did you research and consider before purchasing the Tomei? Quaife seems to be the most popular for the 370Z.

[@thecarizon504]

It was between Quaife, Tomei, Os Giken, and Kaaz for me. I was largely driven by pricepoint because I had budgeted only $1000 for the diff. The other three run you over the $1200 mark. Based on a handful of tomei diff reviews I hadn't seen anyone complaining about quality, everyone had good things to say about it, increased security through the corners etc etc. That's what drove my decision.

[@tobiusmanning7336]

The Quaife is a different type of differential, Quaife is better for time, not as good for drifting.

[@andraestennett3367]

You can put like 4 oz of friction modifier to almost get rid of it

[@wnynj1213]

Thank you for the video i never knew that lsd made sounds like that when turning kinda makes me not want a closed dif when I buy my 370z

[@ReubenAStern]

I was toying with the idea of getting LSD for driving in snow... as it rarely snows... nnnope. If I ever get a track day car yyyyyup!

[@thecarizon504]

I wouldn't get it just for snow, but it definitely would help.

[@scionkai]

Use a better diff oil like motul 80pa.my clanking totally went away

[@VeneraSGF]

Can you still drift with 1.5 way. I would like to have fun as well occasionally

[@Rhyss4K]

very imformative, been wanting a nismo 2 way for ages now

[@davidf5252]

Amazing video! Anyone have experience with a 1 or 2 way in the street? Also, if installing or using brake to initiate is a 1.5/2 way needed for drifting and it or canyon use???

[@ryanscanlan9875]

Great content.

[@eliaconceprio7766]

Hi, maybe I didn’t get it from the vid but your diff in full lock is set to 100%?

[@rferp3480]

This 1.5 way TOMEI, Would you recommend it for use on a racing circuit or trackday?

[@krisk.9691]

would a 1 way lsd not have any clutch chatter? just because its acting like an open differential during deceleration?

[@Kingzogre]

Would a 1 way be more suitable for a daily driver?

[@geeaye64]

Yeah I was thinking the same thing as well. Because of this video I may not do this mod.

[@mikenice1204]

I just picked up a 1.5 kaaz that I'll be swapping in my turbo lexus making some serious power. Will a 1.5 help with traction with roll racing in addition to dig racing?

[@thecarizon504]

Yes,if you find yourself slipping tire at a roll, a proper diff helps.

[@mikenice1204]

@@thecarizon504 nice cant wait to test it out in spring!

[@dupajasiu920]

Im confused now, so where is really the benefit over a welded diff ? I thought it would do better on manuvering..

[@thecarizon504]

It does better for drifting and drag, that's about it.

[@phelanator5784]

Not worth the aggravation for $1500.00 especially if its a daily.

[@luisemiliopirata]

Hey new to your channel here! I was wondering what kind of head unit do you have on your Z? On min 4:36 you can see a long screen. I would love someone that in my Z!

[@thecarizon504]

It's a 10 1" galaxy tab a with the braniacs plastics kit.

[@lorenzowashington5233]

does your wheel ever skip on slow conors

[@slipknnnot]

No joke but you can take some of the corners you demonstrated twice as fast in a normal open diff on a Z and not break traction. For better comparison you should actually say you're in Mexico and show us something that truly makes a good case for it. The noise really doesn't bother me that's what you get with big brakes, more sophisticated diffs etc. It's a sports car not a commuter car. One of my projects for the Z later on will be a 1.5 way diff and twin turbos.

[@markusluftner8418]

I mean 90 kph is kinda slow through that slight Bend, but 180 is not possible without crossing the white line, extrending the radius. He is not on slicks or semis. Also why break the law on camera?

[@tonyhagar9740]

Do you have a vid on the non-clutch type LSD?

[@Nizzi29]

A less aggressive clutch type LSD would eliminate the tire skipping when low speed cornering, right? If the diff had smaller/fewer clutches it would only engage at higher torque values, wouldn't it?

[@thecarizon504]

Yeah, that would be ideal. I ql going to swap mine out for a helical diff from Quaife

[@Nizzi29]

@@thecarizon504 That would be a torsen differential, right? I'm currently looking for a diff for my e46 to get it drift ready, so a torsen diff wouldn't be an option for me unfortunatly. Is the clutch type LSD too annoying to daily in your opinion? Why the swap?

[@CrazYZockerOwNz]

you only got the clicking in tight turns? when my diff is warmed up it clicks also in light turns, do you got this too?

[@thecarizon504]

Yeah it clicks unless I'm giving it a lot of throttle to lock the diff. I am going to experiment with some friction modifiers but ultimately I'm going to switch to a helical type diff.

This was very helpful! I have an S14, it had a welded diff, so I swapped it to an open diff from a J30 and it's shit! I gets stuck just simply driving into parking lots with small inclines if I don't enter it fast enough...from watching this video I'm thinking of going LSD/Posi you think you could do another video describing those?

[@thecarizon504]

Any type of Torque Biasing diff if you care about performance, or if you just daily drive, an open diff should be all you need. It sounds like the one you got was already damaged/worn.

[@gavinpancirov]

I daily a welded diff. It’s not even that bad.

[@EL-sc9on]

What LSD do you suggest for a 370z automatic, I was thinking about wavetrac but I don't know if you need a different type for an automatic

[@Wigwhom86]

Go wavetrac if you can, its all gear driven with no clutches no noise

[@rizocars6115]

So how come a lot of cars come with open diff from the factory and there is no noise, I guess when you go cheap that's what you get, I wouldn't mind spending more in a better diff.

[@thecarizon504]

Price doesn't imply low noise. Open diffs are quite because of there design. A clutch type diff relies on a series of clutch packs and a cam that can make varying amounts of noise. In hindsight, I would have gotten the helical lsd for it's less aggressive lock and lower noise.

[@rizocars6115]

@@thecarizon504 I hear you,. I have motor mounts in my q50, also metal bearing in the suspension arms front and rear, there is some vibration and some noise but nothing mayor, personally that noise is a deal breaker and it takes away the placer of driving the car. I'll get the z1 lsd were there is no noise

[@Ivru]

thanks for the important info on LSD, i drive my car to work and back at 120 miles a day and i dont think LSD will be beneficial and cost worthy on maintenance.

[@thecarizon504]

Deffinetely don't get a clutch type LSD, driving around parking lots is brutal. And if you aren't taking it around a track or getting aggressive with it in the turns there's no need to upgrade.

[@burakoshimazaki]

Torsen

[@anvrchxst4199]

So for my differential on my base 370Z, can I get away with just the vlsd and the output shaft for the swap?

[@thecarizon504]

If you want to stick with Nissan's VLSD, it'll be an easier swap for sure.

[@xpert_kid_one730]

What about a welded dif for daily

[@hackdeez1075]

It's very hard on every drive train (clutch, driveshaft and axles). It will ping, pop and make horrible noises.

[@ubacow7109]

Is there such thing as an aftermarket viscous dif?

[@thecarizon504]

I don't believe there is such a thing for the Z

[@adamnejad6250]

Would you still get a lot of parking lot chatter with a oneway?

[@thecarizon504]

Most clutch types regardless of configuration are going to have chatter.

Does this happen to all clutch type LSDs? Im looking at the Cusco type RS LSD which is said to be used in daily and track driving conditions.

The click will be present but moat likely to a lesser extent than is seen in the cheaper tomei LSD.

[@herrmeez]

@@thecarizon504 And i assume the tight parking lot turning like what you did is also going to be the same with any LSD or does it also depends on the quality? In the video you showed that clutch type LSD acts like a welded diff in those tight corners at low speed.

@@herrmeez you will probably experience some skid like I get but you might be better off asking Z1, they sell the majority of diffs available for the 370Z and have had experience with each. They should be able to tell you the performance different. Plus you can always use friction modifiers to help reduce how aggressively it locks.

@@thecarizon504 Cool! Thnaks for replying

[@MrCarGuy]

Cusco LSDs allow you to change the cam angle which results in different locking strengths and speeds. Great for track use.
