Starting to piece together my front brake conversion to the S550 4 piston calipers. New Rotors came in today, and hopefully pads and new lines will come in later this week. Also Installing new brake ducts, and trackspec hood vent in preparation for my next event at RA with NASA SE in March.

After some headaches with figuring out what brake lines to use and double checking fitting sizes, I was able to have some made by a friend. Came to the awesome realization after the lines were made that the s197s female to hardline fitting was m10x1 which is what I ordered, but the banjo bolt was a m10x1.5. Thankfully banjo bolts are easily obtainable from auto zone, so the new kit is finally on after putting it off for so long. I never want to change a pad on a floating caliper again.

Excited to see how well this new setup will be able to handle heat more than the stockish setup. Counting down the days to get back on track.

It looks like you have the non-Brembo (Frembo) S550 4-piston calipers instead of the S550 PP calipers. The stock rotors have the vent opening by the hub on the outboard side of the rotor. I can't really tell if your rotor is like that or you somehow found a rotor that is vented in the conventional manner (on the inboard side). If you did, that's great and please share the type of rotor you found.

If not, and it too is vented on the outboard side, then brake ducts will do little or nothing to cool the brakes. In fact in may lead to a higher possibility they will crack since the ducts will only cool the inboard face of the rotor and the other side will still be hot.

EDIT: NEVERMIND - After a few searches on prior posting I see that was covered in this post in another thread:

You're using the S197 14" rotors for the Mustang GT Track Pack/Boss 302/non 13-14 GT500 which are vented in the conventional manner and using the base S550 calipers. Did you have to shim the calipers?

Yeah I'm using centric blanks for a 13-14 brembo car. I had to use a washer between the spindle and caliper to center the caliper over the rotor. I wanted to pick up the 6 pots from the s550, but these 4 pots were pretty much given to me from a friend upgrading to the 6 pots.
