So where does all of this stand ?

Did anything ever get resolved or product offered for 5 EAT ?

Well, ClimberD has had the diff for a while now, so hopefully it is installed and he can give us some feedback. Once we get that, we will start looking into producing this diff.

Matt Monson · 06-23-2011, 01:22 PM

I spoke to him 2 weeks ago before I went on vacation. He threatened to get off his arse and install it in the car. But I understand he's had some unplanned difficulties (I think he popped an engine IIRC) and decided to do a fully built gearbox at the same time as installing the diff. He'll update this when it's in the car and running...

It's in and it's awesome. 5eat front torque-sensing LSD is rocking and rolling! Fitment is great. Ring gear fits snug on the carrier, perfect clearance. Bearings pressed on no problem. I cannot speak to the carrier bearing screw caps (not sure of real name) positioning vs stock front diff, because the new bearings were slightly revised, and came with new bearing seats, or whatever they are called that go in each end cap along with an oil seal. So they are slightly thicker. In other words, don't think about being lazy and pretending stock preload settings are appropriate for this diff! Set it up as you're supposed to, of course. I marked the bearing caps to see before and after, and it's proportional, indicating the machine work is spot on!

Setting carrier preload was done exactly to factory service manual instructions, with success. No problems there.

The diff is completely transparent, and as quiet as stock. No problems there.

It pulls the front end around corners! The more power you give it, the more it pulls. It is very exciting. A whole new car in respect to a drivetrain. The front end is more on rails now. No problems anywhere.

My other mods to the 5eat (namely HexMods center differential bulletproof bearings, and HexMods F1 Valve Body) really make the 5eat and this mod shine. I use to be jealous of the 6MT, with its really great drivetrain. But no more! I am now very happy with the 5eat, which now has viscous rear (stock), electronically controlled variable locking center, and Torque-Sensing FLSD!!! Plus with lots more line pressure now, it holds gear ratios effortlessly!

I highly recommend this differential!!!

What else do you guys want to know?

Don't forget to grease the stub axles!

Matt Monson · 07-01-2011, 01:56 PM

You're welcome.

FlatironsTuning.com · 07-01-2011, 03:14 PM

Very glad to hear that the diff is working well!

It sounds like you are seeing similar benefits to what I did when I put the Modena diff in my 5MT. That front TBD makes the car like you always though an AWD car should. And as fun as it is on the street, it makes a world of difference on the track.

Matt and I will have to talk about getting this into production now.

Leonardo · 07-02-2011, 11:45 AM

Or at least a second unit for me!!

I like how they call it an LSD in their marketing. It's a TBD. There's a very real difference between the two and you would think the "experts" at PPG would know the difference...

tbd = torque biasing differential?

do you know much about it? i'm contemplating dropping it into my track toy.

Matt Monson · 07-05-2011, 01:00 AM

A TBD (torque biasing differential) is the type of design used by OBX, Quaife, PPG, and is the same style as the factory Suretrace units. The advantage of them, especially on an AWD car on tarmac in particular is that they have no lock up under braking. They don't introduce any additional corner entry push, but once you are on throttle they aid in power transfer as the inside front wheel starts to slip. It's a great option for a street car weekend track toy or budget racer.

But for a purpose built racecar, most people, tarmac or dirt rally, will go with a clutch type LSD. With multiple internal ramp angles, you can set it up to have little or no lock u on braking and a wide variety of locking characteristics under acceleration. If it's a tight technical course, we run steeper ramp angles and set the LSD to lock later with more difference in wheel speed allowed from side to side. If it's a long fast course with big high speed sweepers (think Road America) then we give the LSD more acceleration lock.

This is purely with respect to the front diff. The way we set up and tune the center and rear LSD is significantly different...

Leonardo · 08-31-2011, 10:48 AM

Hey Matt, updates on when we can get one of these??

My understanding is that ClimberD is trying to put together a group buy on one of the Legacy GT forums. I think Flatirons may be doing the same thing here as well. Basically, we've got to get half a dozen people to raise their hand and put in a deposit to make it worth the effort. Either that, or if people want singles, they are going to cost a whole lot more because of the custom machine work needed to do them.

So you condone treating people like they are stupid instead of making the effort to properly educate them about what they are buying?

Leonardo · 08-31-2011, 01:15 PM

Yep, he does it all the time as he got tired of educating.

For anyone interested, we now have a group-buy thread started.

We hope that there will be a good amount of interest so that we can get this going soon.

Hey guys bringing this thread up to see if anyone can answer a question on 5EAT diffs.

I was just about to buy a 5EAT box for a project but have found out that they are a 3.08 ratio and I wanted 4.44.

So my question is do the ring and pinion gears from the 4EAT bolt straight into the 5EAT ?

I thought I would ask this here because of the work done putting 4EAT centres in the 5EAT.

Thanks in advance.
Ken
