WTB: 3.45 LSD diff or ???

[wally5.0]

Looking for a 3.45 gear LSD diff for my 98 Ti...

Motor setup with be an lsx w/ a smaller turbo so I would like to keep the gearing a bit low to help load up the turbo. It should make 550-600 to the tire depending on where I set the boost so I would like something as strong as possible.

I have read about the medium case e30 setups and those seem to be fairly strong so I would be open to an e30 diff and axles setup as well.

The car will be a driver, rarely drag raced, but I would like to not break axles all the time like my rx7 did.

Please let me know if you have anything.

Thanks!

Chris
