Hi Guys

This is my first post on this board. I,m currently racing a 5th gen Celica on a 1/3 mile oval. I'm looking to add an lsd and get a stiffer final drive ratio. I currently have an S53 trans. What are my low buck options.

Stiffer? Do you mean longer or shorter final drive?

It is my understanding that the S53 trans has a final drive of 3.944. were looking for
something in the middle 4's like 4.56 or 4.77

You'll need to be a member at mr2oc to see this, but here (http://mr2oc.com/showthread.php?t=196352&highlight=teeth+ratio) is a good thread on a similar subject.

Basically, as far as I know, we don't have any options aside from open-slip differentials in the s boxes (and maybe the rare lsd from a 3sge s54 box overseas), and we have the mrs c56 torsen limited slip option. However, the c56 diff has fewer teeth than the s54, so will actually make the final drive longer.

I might be missing some option however.
