Front and Rear LSD?

There seems to
be a lot of info in LSDs for the rear dif but how will the car perform with a front LSD too? I'm fixin to buy a transfer case to get it built but don't know if I should get an LSD put in there too.

It's worth it if you can afford to shell out the extra money.

If your getting the transfer case done then its a great idea to get a new diff. It looks like by your sig you have an 2003. 2003-4 evos (except for RS) came with an open diff in the tcase so it would be a very nice upgrade.

This is what I'm going to get soon. I already had Jon rebuild my whole drive train.
He provides great customer service and has tons of experience.

Also you will need to get the trany rebuilt. That was one of the first big upgrades I did, and it was the best investment I made.
Just remember, doesn't matter how much power you can put down if your drive train can't handle it.

I run a plated front diff with some fairly aggressive preload, as opposed to the helical type the most other run and were factory on certain models. I imagine mine is more aggresive than others, but powering out of corners as the diff starts to lock and I begin to reach the limit of the front outer wheel where understeer begins, if I power through that the front inside wheel locks up and I get the feeling of the front end pulling me through the corner to nuetralize the understeer as opposed to the backend pushing me through it. I still have a stock rear diff (JDM RS) with alot less preload than my front LSD so I know the frontend is doing more work.

What can I expect from an autocross and drag racing events with both the front and rear LSD? I'm pretty oblivious to vehicle dynamics on a road corse so I can't imagine the car with a front LSD too.

It's a lot stronger material and has more splines for strength.

Hmm, I see. I'll have to tell Dan when my transmission gets there.

When I get this transfer case I'll have a LSD put in too. Then I'll research rear LSD options and decide which is best for me.

Sent out the TC to get rebuilt when I rebuilt my engine. Had the quaife installed and immediately noticed a huge improvement from it.
