J-W-G Posted August 27, 2012 Share Posted August 27, 2012 Hey guys time has come to sort out my front brakes on the Escort. I have some FD3S Rx7 calipers here. Pad size is very close to austin princess 4pots used as a common upgrade for escorts. The real thing i want to know is what disks to use? The calipers take a 22mm thick disk stock so ive been looking up disk sizes to fit under my 13inch wheels and im settling on 257mm-260mm disks namely from a BMW e30 or ford focus. The disk measurements are as follows. Stock: Vent Solid Diameter 247 Height 26.5 Thickness 12.5 Min Thickness 11.4 Centre Hole Dia 68 Bolt Holes 4 E30: Vent Vented Diameter 260 Height 35.1 Thickness 22 Min Thickness 20.4 Centre Hole Dia 66 Bolt Holes 4 Focus: Vent Vented Diameter 258 Height 43.5 Thickness 22 Min Thickness 20 Centre Hole Dia 63.5 Bolt Holes 4 For both alternatives machining will need to take place more so with the E30 disks though. What problems will i have regarding the height differences of the disks and how will i need to compensate for it? Quote Link to comment Share on other sites More sharing options...
