1 1/8 Master sizing up new piston caliper size

[$Mike70Z-28]

i have a 1 1/8 master with brake booster 11" I'm looking to up grade my calipers. do i go with the biggest piston calipers or the smallest. they have 3 different size piston calipers

How does the pedal feel now? What size are the existing calipers? What sizes are the new calipers available in? What size are your rear brakes?

The pedal feels good. im going to 6 piston from 4 the back is 4 piston with 3.00 piston area right now

now front is 4 piston
piston 1.75 x 2 piston area 4.80

new 6 piston
1.62 1.38 1.38 x2 piston area 5.06
new back 4 piston
1.75 1.75 x2 piston area 4.80

4.80 to 5.06 isn't a huge difference and should be fine.

There is no way I would run the 4.80 in the back though. The 3.00 is the perfect rear caliper with the 5.06 front, I wouldn't change the area on that one.

thanks Donny i will take your advice

do you recommend the wilwood bp-10 brake pad mostly street use once in a while track

[dontlifttoshift]

Bp-10s will disappear fast on track but will be fine on the street. I would probably look at 20s for the front and 10s in back for a once a year track thing.

It really depends on how you drive on track and how brake intensive the track is and how big your rotors are as well.
