S550 6 piston brake upgrade for S197!

It is finally time for a brake upgrade!!! Every since the 2013 GT500 came out I wanted to add it’s massive 6 piston monoblock calipers to my Kona 2012 GT. I decided that I wouldn’t do brakes until the factory non-brembo package brakes were toast. After an amazing 80,000 miles the front brakes are nearly done. There is probably about 5000 miles left on the factory pads, and I get a pretty decent shudder through the petal during hard braking.

Reviews of the 2013 GT500 brakes weren’t as glowing as I thought so I’ve spent the last four years researching options. Hard drivers have been known to smoke the Boss/GT500 4 pots easily on track. Only heavy cooling, track pads, and race brake fluid seem to eliminate that. I’m not willing to run race pads and fluid on the street. I want to be as economical as possible and run on the street what I run on track. I’m ok with pad changes and I don’t worry about having more options of 18” R spec tires as other are which eliminate the 6 pot calipers.

Reviews of the track pack S550 GT with slightly different 6 pots are glowingly positive. One day while on ebay I noticed how cheap S550 6 pot and 4 pot calipers were. Research ensued and I came across an article where someone had bolted on S550 6 pots onto his 2011 Boss 302 R utilizing GT500 lines and rotors. The S550 calipers differ in the sizes of their pistons and the size of the pad. The pad is HUGE.

This is the route I’m going. I’ve purchased the Calipers, GT500 SS lines (stoptechs), Hawk Ceramic pads, and GT500 rotors are on the way. The only question is will they fit under the Track Pack wheels I bought off here. Will I need spacers, I don’t know. They seem to fit the Boss LS and Street wheels just fine.

My car is in for its hood to be re-painted. To be continued in about a week. Stay tuned!!!!
