| Just use A4 S/S with some copper slip and you will have no problems, most suppliers of S/S will offer either A2 or A4, S/S is not expensive but never use S/S for engine bolts as it has a courser thread than normal metric engine bolts and hence can work loose easier.
I found this out when I bought a set to put on my Jota and was warned about this problem by a very knowlegable chap many years ago, remember that S/S does not have the same tensile streanth as mild steel for such applications like retaining bols etc.
You will have no trouble with A4 on your calipers. |
