So I think I just really messed up, I didn't realize that there were 2 different sizes possible. Do I need 330mm front and back, or 320mm front 307mm back?

I just simply went with amazon's checklist for "this product fits your vehicle" and I think I ordered a bunch of wrong parts lol.

Front rotor ordered: Centric Parts 120.42080
Rear rotor ordered: Centric Parts 120.42088

Front pads: Hawk Performance HB601B.626
Rear pads: Hawk Performance HB370B.559

If there's anything I know, it's that I certainly got incorrect front pads, anyone know what the product number is for HPS 5.0 front pads? When I search on their site they only show the number for the rear pads...

 

AFAIK they don't make 5.0s for the base sedan brakes. Yours are the 320/307mm setup.

 

Yep so looks like I'll be returning both of these pads, I should done my research better.

Any recommendation for other pads?

 

The best pads i ever used are Akebono ceramic pads.
Best bite, no dust, low wear
Waaay better than hawk, Brembo, ATE, OEM

 

Check this place out! Many options. Even on Brad's Centric/StopTech brand. I may have to get the slotted and drilled for 48/corner!
