brake fluid for bbk setup

[adem.csl]

General consensus is either a dot 4(ate) or a dot 5.1
As matt said for trackdays regular changing will see you right but for general road use the dot 4 by any manufacturer is good stuff just don't use dot 4.1 as i believe it won't mix with other fluids where as the above mentioned can mix with no problems(if im not wrong)

You should use Elms, Gareth swapped whatever fluid was in the car with the Castrol SRF I provided and it cost peanuts for them to do. I can't praise him / Emma enough for the service they provide .

4 will mix with 5.1 but not with 5, so 4 or 5.1 are the way to go.

Most race fluids are .4 from what I've seen.
