I think aluminum has similar heat transfer properties to titanium, and wilwoods thermal barrier system sounds pretty cool... only downside I can think of is that the pistons arent fully aluminum, so a fully titanium piston might keep the brake fluid cooler?? But thats splitting hairs on theory Im not even really sure about.
Wilwood makes some good shit though, without some hard evidence that the others are better Id prob go with wilwoods.
PS, Carlos, you are my hero. Let me know when I can take it off your hands
Def owe you one
