I'm going to be doing a rear disc brake conversion, and currently working on writing a cnc program for milling out the centers. i won't be able to get the rotors until next weekend. i was wondering if anyone knew the stock chevy rotor center diameter before machining. any help would be appreciated!

 

What year chevy? I have a 99 Z71 w rear discs

 

why not get a rotor from the auto parts store, mic it out, then return it?

 

^^ X2....or even better....my guys here in town would prolly just let me come in and mic it.... or they might even do it for me...I'd rather do it myself tho....Just gotta ask.

 

i'll x3 that also. i figured that if i didn't get an answer here then i would call a junk yard for dimensions. since i was already on here i posted it anyway. got answer from a chevy guy. i will only need to mill .022 off the center. thanx for the suggestions though

 

Yeah, I guess that wou work too Thats what happens after 14 hours at work no thinky

 

Not sure on the size of the chevy, but it needs to be enlarged to 4.20" for a Landcruiser axle. Is it the same for a mini swap? Can you do more?
