    That's where I'm at these days.

    Though with only a 4.6L I'm perhaps not as needy of anything further up the food chain. Some (including me) have found that the 12-level pad (CT's XP12, actually) doesn't seem to last as long as the 10's, so if I ever do need to move up from 10's I'll be skipping over the 12's.

    When I called CT after cooking thru 2 sets of 12s in 4 days, they informed me that those were actually softer than the 8 10/ 16 18 pads. When I went to 16s, pad life improved under same conditions. Not being able to shut off traction control 100% really cooks my brakes as I do run the car at 10/10ths. Bought the 302S abs module for this year and really hoping front brake temps go down. I have ran through 8 sets of front CT pads , 6 sets of rotors and so far, the rears CT 10s I put on with my 1st set of fronts are not even 5% used yet! No rear bias and apparently the TC uses the front brakes only to control yaw etc. Looking forward to this new abs module so I know TC is OFF!

    Does anyone know if Raybestos makes pads for these calipers? I just picked some up to install on my 2006 and would love to run the ST-43 or ST-45 compound.

    Lol. Their search drop down boxes for a Mustang stink! Too many options that don't make sense.

    I found the FMSI pad profile # based on a general search for 2015 PP pads. Then I just searched for 1792 under "Search for parts" on Porterfields site.

    Putting fixed calipers in lieu of sliding calipers on the back requires more than just a relocation bracket. The play in the axles will cause piston knock-back that may result in more pedal travel until the pistons/pads move out to contact the rotor again.

    In my old vintage car I used tapered roller bearings (full floater axles are difficult to package with mandated rear drum brakes). Those bearings can actually can take side load where roller bearings do not. Does anybody use these on S197 cars? I see Moser has a SKF tapered roller bearing option for their custom 8.8" rear ends. They probably require special housing ends as the bearing is wider than stock. Normal axle bearings would last about two race weekends before they made noise. The tapered roller bearing should have less side deflection under load and basically lasted forever me.

    I also used ST43 pads with great success on the front of my old car.

    I followed-up on the rear GT350 option from Full Tilt Boogie Racing and this was their response,

    "Hello Charles,

    We currently do not have anything available (for the rear). We have been working on something but it is still in the R&D stage and not sure if it will make it to the market yet. Keep your eye out on Facebook and our site for any updates or details in the future.

    Sincerely,
    James & The FTBR Team"

    Given that they have a working front bracket, I remain hopeful for a possible solution for the rears. It certainly will not be simply but this group has done some amazing work thus far. If I hear or learn of something new I will certainly let you all know.

    Best,
    Charles

    Soooo, I did a few auto X events in 18 with the set up, no issues at all. I wasn't able to get to one of the big tracks here though (Laguna, Sonoma ETC). I was on Vorshlags YouTube page this week and he did a video on upgrading the S550 4 pots to this setup, he said that the master cylinder HAD to be replaced on the s550 when doing this set up. Is this the same for the s197? Any of you running this set up see any issues on big tracks and high speeds?

    I did the S550 swap on my Boss. We don't have "big" tracks here in Houston. I have the stock S197 master cylinder. With Gloc R12/R8 pads the car has absolutely no problem slowing down from 120+ MPH on track. Pedal feel is pretty much the same as stock, maybe just a "hair" softer.....
