ordering my pedal box soon, but need to know how to go about ordering which size master cylinders for it, Going on a car that is expected to weigh around 850kg

how do you work out what is suitable, id imagine it has something to do with piston size caliper wise in relation to something else, but dont really know

i know the larger the bore of the master creates more volume, and give a better pedal feel, but thats about it

any guidence would be

 

You can work it out but a good starting point is .625 front and .70 rear and then move up or down from this... If you get stuck give me a call.

 

thanks martin
