If i get an L.S.D for the rear, should i get one for the front too? Or would it be fine with just the rear one?

 

If you are driving an Evo IX as indicated in your profile, your car already has a front limited slip differential. You do not have to replace the front unit if you get a rear differential upgrade.

I'm pretty sure you already have a LSD rear. Or did you mean an upgrade?

 

wow...really?

you've got a helical LSD up front, and an LSD in the rear along with an Active Center Differential. if you're going to upgrade, you can upgrade them separately. look at the TRE maxxlock for a good rear upgrade.

 

All evos come with rear LSD, the different between a good one and a bad one is how many clutch packs are jam in that case. So the more clutch packs the better. Like Cusco rear RS 1.5 way LSD

 

More clutches aren't always better... Depends on driving style.
