Rear 1.6 brakes
 

Hey guys,
Just got a deal on some cobalt xr3 AND carbotechs xp8 rear brake pads. Right now I’m running carbotech xp12 up front (sport brakes), adjustable prop valve and 1.6 rears with hp+.
I’m looking to increase rear brake bias (I know I should probably run bigger rears, but trying to work with the 1.6s for now).
Any input on which pads I should try first? Both compounds seem to be quite similar from what I have read on various forums...

Thanks for your feedback!

Ben
