I was looking into correcting my lsd plates in the rear, and is the 12 plate worth the 180 over the stock corrected lsd plates? Street tire Slick...

I understand that a 1.5+ diff would be the "best", but thats not what I want to know.

Did quite the searching for reviews no one really talked about the difference between stock corrected and 12 plate from weir.

Also are the plates/discs/clutches whatever u want to call it... an upgraded quality vs the stock plates. They look like different material and I assume they are smaller to fit 4 more in. I would rather keep the stock like duribilty than open a can of worms. I hate playing with gear oil!

Anything I missed as far a Q's on the 1 plate and stock corrected lsd chime in.

I can't believe I didn't look into this years ago wtf!

Thanks

 

Probably cuz not too many people go from one to the other unless they're REALLY unsatisfied with the 8 plate

 

Bump as I would like to hear feedback as well. I'm at the same place you are, not sure If I am going to upgrade or fix what I have.

 

I never did the corrected stock plate mod. I got the Weir upgrade and arranged. Now that I've gotten a little more used to the power of my car I can safely say the rear rotates alot better. Its predictable if the tires lose grip.

 

can't believe no one has gone from corrected to 12 plate

 

i corrected my plates for the last two events this season, the results were alright but i want more lockup. Im ordering the weir kit this winter but i wont be driving the car till next season

 

i would think its because most who do only corrected just do it because they are restricted by class restrictions, otherwise there's really no point to just reshuffle them (save a few hundred?) when you could have way better performance from a 12 plate

 

Maybe I wasn't clear. I did do the 12 plate weir upgrade. I'm still getting used to the power of my car but I have been testing the limits and there is a noticeable difference now. The rear does rotate a lot better.

 

So the 12 plate is much better than stock corrected?

 

Better in performance? Maybe. The 12 plate is very tight in the diff and lets the diff lock up faster and harder compared to arranged plates.

The Weir 12 plate is still fairly new to the Evo scene so not many ppl have done testing with them nor want to take apart their diff a 2nd time to install 12 plates.

 

right, and they are working on a 1.5 way version

I think in general the more potential lock up the better - because anything less you can modulate with throttle, right? Making a car oversteer with a differential isn't the same as making a car oversteer with sway bars, because with oversteer from a differential you can add back grip to the rear

 

boosted91t seems like the 12 plate is the way to go.. found some more info here

Depends what you want from it, we've dome a few of the plate rearrangements with great results. We can achieve on power oversteer without a problem on performance street tires. We've also set up stock diffs that were agressive enough to chatter and skip the tires on turns.

The plates are the same material as stock to my knowledge.

I assume they are smaller to fit 4 more in.
Thinner

There's a couple vids in this thread of a stock corrected diff with less FM in it.

Stock diff rearrange as well

From pictures they look different, but never had any in my hand....pictures may not reflect actual product.

Im looking for information to swade me one way or another, fix my lsd, or fix and upgrade to 12 plate the same time.

I don't want to do the fix only and need/want more lock and have to pull the diff again.

Does the stock corrected lsd produce a usable amount of oversteer on summer street tires?
Does the stock corrected lsd produce a usable amount of oversteer on race slicks?

All saying stock like supension settings with the evo's natural oversteer


I'm currently on star specs and will be getting slicks once the stars are gone. I mainly road course the car not much street.

From reading and recommendation and what not... I pretty much set on getting the 12 plate.

From what I gather, correct me if i'm wrong, the corrected lsd is a great improvement, and its the way the car should be. Especially on the street. On the track not much an improvement to take out the push or understeer.

And with the 12 plate, an improvement over the correct stock lsd. Could be a little much for the street, but on the track a must to muster some desired oversteer through a corner.

And then you have the super duper aftermarket diffs (track diff) which change the diff to your spec and strengthen it, biggest change being 1.5way. Which gives some lock up during coast. Which to my guess creates better turn-in on the track.

 

If you're talking about the Weir kit, it looks the same as the picture on his website. Just plain discs with no grooves in them. Don't know the material but I'm sure it isn't brittle.

IMO, just go for the 12 plate. That way, you don't have to look back and say "Man, I want more lock" as you'll already have the best lock you can get before spending $1000 on aftermarket diffs.
