This is my first year in IT, and my first year road racing. I picked up a ITS prepped 77 280z.

It came with a welded diff, and after a interesting discussion with an experienced road racer, and engineer, I am confused. He says we should swap in our open diff for the welded diff, and he also says to NOT upgrade to an LSD.

He feels that we should spend more time with our suspension setup, perfecting it, and we won feel a need for an LSD, at IT-S power levels.

Anyone else feel that the z platform can be setup in a way that the open diff wont be a limitation?

Thanks,
Josh
