I'm running MT STs in 255/60 rear and 215/70 front. I went with the 70 series up front to stay close to 27 inch diameter to fill the front wheel well. They are about as tall as will fit on an ERA in front. They seem like real good tires although I can't say I've pressed them a lot.

Evan - can't remember if you went with an aluminum block or iron block - with an iron block I think you will be around 2650 - 2700 lbs or so. With an aluminum block Rockbits weight sounds about right to me. your undercar exhaust might weigh a few more pounds but you will probably save a few pounds in wheel/tire weight.
