(Flame Suit On Check) I do not like the single-pot floating brake calipers used on these cars for track driving. Yes, I know, some people use them (with track pads and SRF), and I know some series require them, and I know people get by with them but I also know people that have had major issues ( Flying off turn 1 at SP and hitting the wall, etc) with them including me (I just almost flew off but did not hit a wall). To that end, I decided to go the following route as mentioned in the title. So
First Step: Get some 996 / Caymen S Calipers I got mine from John Ts deer strike 996. This seemed like a good approach because in theory, they had the fluid changed frequently ( was a Tech Inspector and is an Instructor) and I got a complete set from the same car.
Then,send them to Rally Road for a bit of machining 5.5mm off the mounting pads to be exact.
On go the brackets these are beautiful. Note the mounting studs so that you do not have to Time-Sert the suspension parts after you pull the threads out upon removal (you know who you are). I did have a slight issue with the stock mounting bolts. The shoulder on the bolts bottomed out on the threaded bracket before I could get to the correct torque. A thick washer between the head of the bolt and the suspension mount holes fixed this. I need to find a better set of bolts and remove the washer but this is fine for now. The threads on the RR brackets come right to the edge where-as the stock brakes have a slight reset for the bolt shoulder to go into.
Next, on go the rotors. These are 345mm by 28mm rotors used on a ZCP/CSL. In this case, I went with the ECS versions of these rotors. These look to be OEM 2-piece rotors, modified and drilled. I could have gone without the drilling but these are heat-treated, have replaceable friction surfaces, and are pretty. We will see how these hold up. I inserted a screw-driver to check which way the internal vanes were going. It turns out PFC also makes a set of 2-piece rotors that should work. Clearly, when these brackets were designed, the designers put as much meat on them as possible at the point where they are threaded and bolted.
WOOPs First Issue. The bottom, inside pins on the brake calipers were making contact with the rotor after the caliper was installed. None of the threads I saw mentioned this, so I filed these down a bit, approximately 1.5mm with a hand file to get clearance. I may need to file a bit more we will see. Others options to considered, if it is a problem, is take the rotors apart and have the faces machined 1mm.
The calipers go on easy now.
The rears were the same but required no filing but did need the dust shield trimmed.
Here, Kitty completes his inspection of the custom DOT approved brake lines (also obtained from RR) and indicated his like by lounging next to them.
For some stupid reason, I forgot to take some pics of the completed project without the wheels on but oh well. I used 10mm spacers on the front but 12.5mm spacers would be better for a bit more clearance will change if there is an issue. Please note the beautiful wheels. Wheel Doctors did these in satin graphite. There is not a lot of info on this setup in terms of pads but I have decided on DTC-60 all around as a starting point for track usage.
