I've had R4S's completely disintegrate (worse than the pictures) from street driving... Granted, it was almost a 200-mile mountain drive, but it was still street driving.

 

A couple of comments:

- If fluid boiling is a problem, try Castrol SRF. It appears to be expensive but due to its high wet boiling point I have found that it lasts at least one year and never requires bleeding, so it is in fact quite cheap compared to pad, tire and gas expenses.

- Removing the dust shields does not increase cooling significantly. You will still need to replace pads and rotors and service the piston seals about as often as you did before.

- Same goes for the 2" C&T duct system. If you are hard on brakes it does not improve the situation significantly. The inlet scoops are also exposed to damage. One track off or an unexpected driveway bump will strip them off the car.

 

see below.

 

i found these electric blower fans that fit inline for 3" ducting for brake cooling. Are these of significant use? i.e. do you think they would be needed or yield real benefit to the S2000 or are 3" passive ducts as much as you need? anyone have any experience with these. i think i'll get some.

the race shop i was at says they really blow hard, he carries all the other ducts and tubes shown above....used for some late model stock cars, short ovals i presume. any websites carry these? i was under the assumption this would force more air than simple passive ducts and tubes??

Might not be a bad idea (fans). The only time I've gotten fluid fade is if I don't cool the brakes enough before pitting (say, if I came in before the checkered w/o a cool down lap).

they are basically hairdryers w/o heating element

 

Stick your hand out the window when you are going 50 mph and feel the wind pressure. Your hand is probably about the same size as the brake duct cutouts. Now imagine what kind of fan you might need to produce that same force...

The pressure is not additive; The fan won't take that force and add "just a bit more" to it. In fact, it is likely to impede the flow somewhat at higher speeds.
