I am looking for a new Wilwood MC, and I have found then for CHEAP. Now my question is, what would be the difference between going with a 1 inch bore, or a 1 1/8th in bore? Would I notice the difference in braking power?

look at part numbers 950-260-8555 and 950-260-8556. They are the same except bore size.

well considering the bore size determines basically how much fluid is getting pushed.....

And you are looking at a 1.000, and a 1.125" bore,
The 1 1/8" bore is substantially larger, and you will feel that in the brakes. I see you hve wilwoods all around, so an upgraded master would be highly recomended. Perhaps Wilwood would answer this question better then most of us could.

They know thier products better than anyone here. Drop them a line, I am sure they would help you properly size the master.

OHHHHHHHHHHHHHHHHHHHHHHH Trust me I have talked to Wilwood, They said I could go with either one of them. And didnt really give a reason for or against either of them. So thats why I posted here on the ever so trusty .ORG. They have the same MC from 7/8 to 1 1/8 in 1/8 inch incraments for the same price...i think i am going to go with the 1 inch MC and have a nicer pedel and more power for all 4 corners...i think the 1 1/8 will be a bit of overkill...

I think thats a pretty accurate assesment.

DONE!!! thanks for the input John!!
