Hello solman98, i want to change over to the larger front rotors. I have 16 inch wheels on my 2011. i find two different part numbers. one for 4 wheel disc brakes, like in your picture. And another part number for disc/drum setup. Is it ok to use either number? Do you know what the difference could be between the two? Could it be spacing of some kind? Thanks for your help. Jethroc.

Sorry for the delay, I'm not here much. I don't remember which models I went with, I ordered them through Best Buy. I am very happy with them and I'm still using the stock head unit.

Hi there,

Just ran across your post on the forum here, I have a 10 HHR that was a rental vehicle, I bought it a couple years ago or so from a Chevy dealer, it has the base non-Pioneer stereo system. The front 2 driver and passenger speakers in mine are out and I'm looking to replace the ones in the front and rear doors, factory tweeters seem to sound ok.

I saw your installed new 6.5" Kenwood coaxial speakers. How do they sound and which model Kenwood's did you go with and are you running the factory head unit?
