Don't forget the cost of wheels if upgrading to Brembo's as the OEM R\/T wheels won't fit. I figured about $2800 for a full swap when I had to include buying wheels.\n\nThe BR9 swap is a decent low cost option to upgrade to 4 piston Brembo level braking, but finding the calipers is getting really difficult. Most parts houses seem to show the parts until you pay for them and then they magically become back ordered with no ETA. I bought used calipers front and back, and have the dust shields and hoses, just sitting on them until I can drum up the cash for rotors\/pads.\n\nAs I understand it, the BR6 brakes really are just BR5 brakes with a more aggressive pad. So if you want better braking without the hassle of a full swap, I would look at figuring out were to buy BR6 pads and go from there.
