Bingo.

Alright. Here's what I've got:

Left Front: Min: 5918g; Actual: 6029g
Right Front: Min: 5870g; Actual: 5984g
Left Rear: Min: 7915g; Actual: 7994g
Right Rear: Min: 7938g; Actual: 8009g

Now, that said, looks like I have the common groove on the inner portion of the front rotors both inside and outside.

There was a thread at one point, someone weighed a new set and each came in at about 100g over the min weight. It must be said that weights vary from rotor to rotor because of their composition. The true answer is they would have needed to be weighed at new. But, 100g is a rule of thumb..I suppose, you know, grain of salt theory. Doing the math here, you scrubbed +/- 20g in 50k miles and 5.5 hours of track time. It absolutely MUST be clear, I am not an expert on this, just making observations. I believe there is good life left in those rotors. A few track days or another large sum of miles, so maybe selling them take 35% off msrp? Or keep them for resale value if you ever wanted to do so. These are my OPINION!

Your opinion is pretty darn close to what mine is. I figured due to the lack of pushing them to their potential they were in pretty good condition. Do you think the groove is something to be concerned with at all or is it like everyone says in regard to being relatively normal?

Edit: Also, I'm not overly concerned with resale as I have no intention of selling this car whatsoever. I'd rather sell these rotors off to help fund other things I want for it, even though I love them.

Chevy2tehbone - do you have pics of the front of the rotors. Based on your weights i'm suspecting rotors that show the significant wear patterns others are posting are at or below spec. Thoughts?

Giro Disc / ST43s here I come

Yessir. Here you go.

Well, here goes nothing. I put them up in the for sale section. Onward and upward!
