Excuse all these quations but I am going through my car for next season and I hope most of this will be useful to all of us.

At what thickness do you replace the rotors? I gather that the minimum is 20mm for the fronts but what is the original thickness? Mine appear to be at about 21mm and that sounds like time for new ones if they started at 25 but not if at 22.

it might be overkill, but i replace rotors every time i replace pads. i am a maintainence freak because i also change all fluids after every weekend. seems to keep the car pretty reliable.

Thanks guys; since mine are only half worn (22-1=21) and otherwise in decent shape, I'll get another season out of them. Where's the cheapest place for Hawk blues?

Michael, either you need to check your sig or I need to check my GCR. http://Forum.ImprovedTouring.com/it/smile.gif

BTW, where are you located? Plan to come to Michigan?

A forum sponsor (at the top of this forum) Raceshopper.com is where I get mine at $121 for blues in the front. I think they are currently giving free shipping if you buy fronts and rears.
