Caliper and rotor sizes

[protour_chevelle]

So my 12" Baer kit rotor is 1.100" thick... I'm going to be running the impala rotor soon and depending on year I can get a 1" thick or 1.250" thick rotor...

I haven't seen one caliper specifically for 1.100" rotors on circle track sites that sell the 1" or 1.250" Impala rotor.

Am I able to run the 1" rotor or 1.250" caliper???

Thanks to anyone(s) that sheds some light on this topic.

The early, pre 78 I think impala used an 1.25 rotor, the later, which is what veryone used for the spindle and break upgrate is a 1.1" 12" rotor, they are NOT interchangable. Wilwood makes a GMiii caliper that is for the 1.1" rotor and has ruber mounting bushings, you still need AN braided hoses to the caliper, but they work nice and are light and cheap!

71-76 are 1.25 rotors

78+ are 1" not 1.1" The Baer rotors I'm using now are 1.1" x 12" rotors. (factory kit)

Curious though... Have a part number on the calipers?
