14.5" front rotors?

723 Views 4 Replies 5 Participants Last post by  thebigjimsho
Hey everyone

I recently ordered a set of front and rear rotors (slotted & drilled) from a company online. They have been great in expediting my needs but I am a little concerned about my front rotors.

The company that I bought them from sent me their cut-sheet on my front rotors. I purchased 120.62075 CTS-V rotors that are supposed to have an overall outer diameter of 13.98".

Instead, I received front rotors that are stamped 121.62075 and clearly have an outer diameter of ~14.5".

Can anyone confirm that this will be acceptable? Anyone have any experience with these types of rotors? The company that I bought them from assures me that this is no problem but I want to make sure since I won't be installing these for some time (they were a good deal at the time).

thanks guys!

I was wrong...delete this post :bighead:
Im pretty sure the Rears are suppose to Be 14.5" To accommodate the Inner Parking Brake Hub - The Fronts should be 14"

The only reason I remember this is because I thought it was weird that the Rear Brakes were larger than the Fronts (usually the opposite) and came to find out it was for the parking brake. Either way good luck!
Only way to know for sure is to try a fit test. If you can't do that - which seems to be the case, since you're saying you won't be installing them for some time - just do a quick check for measurements and see if you've got 0.25 inches of clearance between the wheel and the caliper.

Fronts are not 14.5 stock.

Exactly. Make sure you're not looking at the rears...
