May the search be with you...
Ok:
Yes you can use cressida front brakes on a 86
Yes you can also use RA60 front brakes on a 86
Yes they work quite well (Remembering that 86's are only a 900kg car)
Yes they are much heavier per side than the factory struts
Yes they upset the weight balance
Yes you have to adjust the brake bias
Yes JDM calipers and rotors are the better option
(Sorry to sound like a tool, but this has been OVER covered both on here and toolmods)
