The 205s fit on the normal bundts with no problem. They increase the effective final ratio by a couple of percent. I was just trying to reduce my highway rpm a little without switching gear ratios. They are tad wider, but most people would notice that they look different. I like the 205s, I don't see any disadvantages.

Awesome, I will probably do that too, I'd like to drop the rpms a little without swapping my diff (yet )

It's only a 2% difference, so don't expect anything dramatic.

I know, but anything helps....even if it is only 75-100rpm. Eventually I need to acquire a 2.88 diff.....

Or just find a 400E or something.
