Wow...they look nice. You'll like the PFC01's, I hear they're top notch. Maybe too powerful for street rubber, but brake modulating is just another skill to learn. Seems to me like they are very forgiving when you fall below operating temperature.

As for the Castrol SRF, are you sure you want to use that? Here's what I don't like: Castrol SRF exceeds the US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925, JIS K2233 and current SAE J1703 and is miscible with all conventional brake fluids conforming to these standards. However, mixing Castrol SRF and conventional brake fluids will reduce the benefits of Castrol SRF. It is strongly recommended that conventional brake fluid be drained from the system before flushing and refilling with Castrol SRF.

I am hard pressed to find an issue with the ATE fluids, it's cheap, it's everywhere, you can mix blue and gold and even Motul or Castrol. The premise of Castrol really bothers me as requiring you to be 100% Castrol...you might find an occasion when you're at a track and you need to borrow or buy someones fluid. If you use it, then you have to flush it all out to get the Castrol 100% again. I haven't even mentioned the ridiculous price the want for it. Remember, an open container should really only be kept around for about as long as you'd keep soda around....with similar rules...the more the lids off, the less time you can keep it. You're just starting in this game, and I'd hate to see you spending money in places that aren't really necessary to have fun. YMMV.
