Manchester would be fine, I go up to Norm's Detailing there occasionally anyway!
I'm not sure where you are at chevy 3, but it would be great to see you again and I'm sure it would be worth the trip.
To answer the other questions- I think it makes sense to do all 4, I bought them already. The stockers are in there now, but I wanted Hawks because they were great on my GTO (less dust, etc). My understanding is you do NOT take the calipers off. I also read that you didn't need to do the rotors? So I didn't plan to, but I will if I should. Advice?
Oh, and about my polished wheels. I didn't realize I forgot to reply. I am planning to swap my wheels, and had purchased some new ones, but got jerked around on the widths of the rears and ended up cancelling. I am still trying to make a change and will get rid of mine.
