So a productive day collecting some new fluids and some heat protection.
Revolution Racegear was the only place I could find who stock (or next day order) the DEI Products for anyone else interested.
I was told you can ~1L to flush brakes and ~0.5L to flush the clutch so hopefully that information was correct
Is it still considered correct to bleed the furthest from the master cylinder to the closest, EG;
rear left, rear right, front left and finally front right.
