Is anyone using BREMBO LCF600+ or Castrol SRF for HPDE's?

I'm considering going to SRF simply because I can increase my bleed intervals, but the Brembo fluid is 1/4 the price and has good specs.

The Carbotech site says, "IMPORTANT NOTE DO NOT USE Brembo LCF 600+ fluid in contact with any type of magnesium components (e.g. gearbox / clutch components) as a chemical reaction is caused resulting in gases being generated. This will then prevent the clutch hydraulics from working efficiently."

Thoughts any of this?

Castrol SRF user here, expensive but worth the outlay

I've always used Brembo LCF 600+ on my previous track car, Renault Megane RS265 and never had issues.. I still have some new bottles left which I plan to used on the Type R as well!

I appreciate the feedback!
