Hi All,
I am just at the point of putting together my "braking shopping list" for my Spire GTR.

Is there any benefit in going for 1/4 copper/nickel pipe over 3/16 ?

Cheers

3/16" diameter is the standard size for car brake systems, I do not think there is any advantage in changing it.
Hyraulic clutches on some cars use a larger diameter tubing.

stick to 3/16, going up to 1/4 just means you will need 33% more fluid in the pipes

actually 77% more....I think
