Trying to find out some specs for the front brakes
Stock rotor size (thickness and diameter).
Stock caliper mounting hole width and hole diameter.
Trying to explore some cost effective brake upgrades for us.

Exploring some stuff with a brake company. 4 and 6 pot, 12" rotors. Just trying to compare our mounting stuff to theirs

You'd have to make either a bracket extension for the stock caliper to mate with a larger rotor, or a get a new caliper to mount a larger rotor. Which brake company?

Looking for the mounting hole distance from bolt to bolt. There is a magic number were looking at and I'm hoping to find it. Anyone have a set of calipers off the car?

The caliper frame mounts are exactly 140 mm O.C.

CTScott. Is this 140mm to center of hole, to outside edge, or inside edge of bolt hole?

^ O.C. means 'on center', so it is 140 from center of hole to center of hole.

Ahhh ok. Then we may have a winner. Gonna see about them sending me the relocation bracket to see how it lines up. If all goes well I'l have a BBK in the next month at a rough cost of $650, 12" rotor 4 pot caliper.
