02 C4S minimum rotor thickness please

I have searched for a few minutes and found the spec for a GT3. Can't seem to find C4S/Turbo

Anyone have the info handy?

thanks

Thanks for the quick response Loren, got them off and getting them done tomorrow morning. I have 1.33in = 33.7mm. Should still be enough room for a skim.

So I have been hearing a slight squeal when breaking intermittently for the past month or so. I figured it was the wear indicator, so I pulled my wheels to see how things looked and get an inventory of parts for a brake job. I have an 02 C4S which appears to have the same minimum requirements as listed above.

My rotors are 32.75 mm front / 27.25 rear and the pads are a little over 6mm front / 8mm rear. Would you suggest doing front and rear? Just pads or pads and rotors all around? I picked up the car 2 years ago with 36k miles and it is now pushing 50k. This is my first brake job on the car, so I am not sure how much wear I should anticipate on the rotors before the pads are ready to be changed again, or how quickly the pads will go. I drive the car daily, but have not had it on the track to date :cursing: . I closely inspected all four rotors and do not see any hairline cracks which is another reason I am debating which way to go....

Do the dampers and caliper springs need to be replaced every time breaks are done? I know it is recommended, but just want to know if this is a real world necessity.

I am leaning towards replacing everything but do not want to throw money away unnecessarily.
