LSD for an Auto?

just looking and reading about boosting. Seems a Limited Slip Diff is a recommended upgrade for any kind of boosting. Does anyone make one for the ATX focus? read alot about Quaife and Torsen. I think Ford Racing all makes one too? But i havent found anything relating to if they are MAN or ATX specific.
But yeah im looking for an application for the ATX.

lentech used to make them, not sure if they still do. if your boosting you will need a build ATX anyways, so it might be worth looking into a full tranny from them or PA, ect.

Lentech still makes them. The ATX mission will need machining to get the MTX75 type differential in.

then why would i buy the MTX75 diff?

and im not building the ATX, just boostin it till it breaks. If it aint broke, dont fix it. i know a few people that have JRSC's on there autos and have been running them for 40-50k with no problems.

just called and asked.
They said they dont make one for the ATX, but if they build you the transmission i'd have the option of going with the MTX lsd, and then they would machine out what needs to be done to fit it.
In other words, not worth it for a JRSC lol

I guess I mis typed what I really meant, Lentech doesn't make differentials, but what they use is the T2 Torsen. Len or Chris should have told you that over the phone. If you're on a JRSC, you don't need a Lentech as you are not making any serious power. But they are nice to have for added security and drag racing.

@ Boosta: if you have a Lentech now with no differential in it, you will have to send it back to them to machine the housing to fit one.
