Are they worth the upgrade? If so, what brand?

 

They are worth upgrading, but usually not worth it unless you do some major stopping....or live in rainy areas.

you can pretty much go with any brand, but the lower quality ones can crack more easily. I know tons of people with ebay ones and several with expensive ones. all work good and haven't had any problems with the ebay ones.

 

x2 on top...brembos is a pretty good brand

 

Not im my opinion, oem or brembo blank rotors with some good pads will be a better combo.
