Got my big brake parts... some questions

[LS6 Tommy]

this might sound stupid,
but are those GM part numbers, or numbers from a local autoparts store?

Those are the universal non name-brand part numbers like a scrapyard or a parts store uses. I forget what the system is called.

One more question, what i cant find in any big brake topic.
As ive seen the 1LE rotors require metric lug nuts. 12x1,5
So i have to change them on front?

Yes, or you can have standard thread studs installed in the 1LE rotors. I opted to just use the metric lug nuts on the front of mine.

I put 1/2" studs in mine to match the ones on the rear axles.
