Will this work?
 

After I'm done with my Motor swap, going to look into upgrading the brakes to go with the new power.

I have an 87 Suburban with the JB7 Brake code (1.25" front rotors).

I am looking to converting the rears to disk using this kit:

And looking to install some stoptech drilled/slotted rotors up front with these Willwood Calipers/braided hoses:

either these:http://www.wilwood.com/calipers/Cali...o=120-10936-RD
or these: http://www.wilwood.com/calipers/Cali...o=120-10938-RD.

Not sure which front calipers to get as I'm not sure of the Piston area.

Would this setup work? Anything else I would need?
