Hello I need some advice . I have recently put a s14 sr20det into my 1981 ae70 lift back. As with the power upgrade it is certain to say I need better brakes and suspension. I have been lucky enough to have been gifted some s13 front brakes but is as far as I have got . Was wanting help on what master and slave to use what else I need to put the brakes on and what affordable rear brake combo to use in conjunction with the s13 front . And also a way to get around Nissan front and Toyota rear stud patterns . Please help!!
