I apologize ahead of time if this has been covered.
I am trying to find the actual measurements for the front rotors on my 2010 HHR LT 2.2L.
I'm not able to take the wheel off myself to measure it. Sorry and thanks in advance.

 

Why do you need to know?

 

I've ordered the wrong ones online and need to return them and in order to get a return shipping label they are requesting the size of the originals.

 

Somebody probably knows.

Hard to say, could you go to an auto parts store and pretend to be a customer that just happens to carry a tape measure?

According to this thread they are 10.6 inch.

Okay thanks so much. I'll just go with that. Lol. Have a great day.

 

Not sure how you know they're wrong if you haven't had the wheels off. Unless it is extremely obvious.

 

I once fat fingered a rotor order for a Toyota P/U. I just couldn't make the 6 holes fit on the 5 studs.

 

Yes of course, very true!!

 

If you ordered the larger 11 3/4 diameter rotors for the 2008 to 2010 SS non Brembo, then read this thread and upgrade your brakes!

You'll be very glad you did!

 

Kellywren, a great resource is Rockauto IMO.. for looking up parts, dimensions, etc. Advanced and Autozone aren't to bad out by me, not sure if you have them in your area..
