one track day told me of my need for them. brake fade is a very scary thing coming into a corner from 110mph. rubber lines tend to expand under pressure, which is increased when the fluid is boiling (like mine was) which is one of the larger factors contributing to brake fade. and yeah, from now on i will be running track specific dot 5 shit, even the best stuff you can pick up at an autoparts store is worthless after about 6 or 7 hot laps. im still going to look into this, as long as the threads that physically connect the line to the caliper and the line to the hard line are the same i dont see why it wouldnt work. theres a good chance they might be different but if they arent im gonna at least see if theyll link up.
