Master Cylinder for 4 pots
 

ok is it worth moving to a 23mm gti6 master cylinder or will the standard vts 21mm do the job?

More pedal travel with standard

more pedal travel but will the feel be better than the 23mm one?

Persona preference, when I put 266mm brakes on, the pedal felt better with a 23 mm master cylinder. Worth it for a few quid

On my car I fitted ap-racing 4pot calipers with the original master cylinder... and the pedal is perfect...
