You're right, I worded that wrong. Ti shims, or any shims for that matter, will help reduce the heat transfer to the caliper & seals, and will help reduce the possibility of boiling the fluid. If NOT using shims, the heat will go straight to the caliper and seals. Using the Ti shims will keep the heat at the pad and rotor, which also isn't great. Best solution will be proper cooling ducts to keep fresh cool air going to all parts.If titanium transmits heat poorly, your statement makes no sense. It is the pad and the rotor that will run hotter and hopefully the caliper will be a bit cooler meaning your seals will be at least a bit protected. Also by running the rotor a bit hotter, the delta between the incoming and outgoing air will be higher which is actually going to be a bit more efficient.
