Thumbs up Upgrading RB BBK to 4 piston calipers

I finally got everything , including time and installed my four pot front calipers today, along with the stainless lines (finally). The install was pretty straight forward. I unbolted the front calipers, by removing the bolts holding the caliper brackets, and disconnected the brake line at the top. This way everything came off in a neat package. Installed the new mounting brackets, then calipers, lines, then dropped in new pads and retaining plate and bolts. Swapped out the rear lines and was ready to bleed. After unhooking the battery, I used my hand vacuum bleeder starting with the rt rear, then moved to the left front, and bled the outer first, then the inner, moved to the left rear, and fnally the rt front, again doing the outer bleeder first. I was quiet easy to rell when the lines were clear, as the Super blue fluid shows up easily. I followed the same sequence one more time and finally checked each corner one more time the old fashioned way (pumped the brakes.
Based on my experience, the factory specified sequence worked very well with no issues, and lines all show no air.
First impressions, after bedding in the new pads, the brakes are impressive. Will stop on a dime, with no drama. Same pedal pressure results in about a 10 percent reduction in stopping distance. Only stopped short for a few stop lights this AM.

before new calipers, or paint

What caliper does RacingBrake use? Do they rebrand another existing caliper or is it their own design?

They look great BTW.

Based on their website, and conversations with the tech people, they are their own design. Also they just redesigned there calipers, as well. One nice thing is the 4 piston design use the stock size, 300 Twin turbo pads, so you can find pads easily if necessary.

Nice!
You got. Bought them from a member here, thanks 350Zenophile, center caps are a straight switch. Even the TPMs interchange. Offset makes them just about flush with the fenders, no spacers needed.
