Anyone have luck with slotted rotors?

So from your experience on the track you've had no fluid related problems when using Motul 600 or AP 600 fluids? That's good news.

Eventually (as your skill increases) you are going to need to add brake cooling ducts.

It was mostly that they burned through the stock pads so quickly that they lost the pad protection layer (the pad material is an insulator). That allowed the fluid to quickly boil from the radiant heat. If you can find titanium shims that fit that will also give an extra layer of protection and help your dust seals survive more than 1 event. Brake ducts would be good too.

That's my thinking, it's your brakes, you REALLY want them to work!

SRF should be a winner on the street as well, what with its very high wet boiling point. Is there any reason not to use it on the street?

I've been thinking about the brake ducts as well but it will be some time before I get serious on that issue.

Titanium shims would offer some protection for the dust seals and the brake fluid, are they available and if so where and how much?

The only issue with SRF is corrosion. With stock fluid you can replace it and forget it. However, with SRF it must be flushed before 18 months (per the instructions) or you can do some damage.

Is it the fluid that does the damage or does it not provide a great deal of corrosion protection so it requires regular flushing?

It is because it is so resistant to absorbing moisture. Most fluids prevent corrosion by absorbing moisture but the high end racing fluids resist absorption.

So regular flushing of the system keeps the moisture at a manageable level, got it. I guess it's Motul 600 for everyday use and SRF for serious work.
