944 turbo and non turbo calipers
 

will 944 turbo calipers fit on non turbo aluminum rear arms? if not is it a easy switch?

From what I understand they will bolt on just fine. I think that you will have to use some washers if you want to run the non-turbo discs to space the calipers correctly. No spacing will be required if you run the turbo discs. Does you trailing arm part number start with 951.***.***. I'm not absolutely certain but I hope this helps..... :)

great !!!!!!
thanks for the info
