Which disc brake conversions have others used

wilwood has a conversion kit that uses your stock drum spindles. i believe it narrows your track width 1/4 inch per side and has dual 4 and 4.5 bolt pattens in the hub if you ever go bbp your good to go in the front end department.

but im not sure you didnt say what kind of car you want brakes for?
do you have 9 or 10 inch brakes now?

dont take my word for it just do a little research on the correct wilwoods for your application. there are probably variables im not aware of

personally im going with the factory 73 and up spindles/brakes so i can get parts anywhere when i need them. im not gonna build a space shuttle. i just want to cruise again.

im sure somebody with more knowledge than me will chime in after you let us know what your working with.

this kit says you have to have a larger center hole in your rim (3.05")
