Post Front LSD ? Is it a direct bolt on??

Hi guys! I had a question about the front LSD that Sti sells. Is it a direct bolt on to our 2.5RS?

I guess I'll mod first things first and start with the Sti/Spt short throw shifter I just got in the mail!

Anyways, I'd appreciate it if somebody had an answer to my question.

The WRX front diffs do fit the US tranny. However, you need to change a couple things, including the stub axles, according to Trey. Now, "bolt-on" is another question... If tearing apart a transmission is "bolt-on" then you are a vastly superior mechanic than I am I consider tearing the tranny apart about the biggest pain in the butt thing you can do on a car, second to rebuilding an engine, which I just recently finished and will likely never tackle again... the time it took me, I could have paid someone and then made the money up working and still had time to spare

I would not install a clutch-type mechanical LSD in the front unless you spend a lot of time offroad. A better choice would be a Quaife (torsen). Quaife would also be a good choice for the rear diff, again unless you are rallying. I get the feeling most of us are the tarmac sort.
