Just did my fronts again yesterday afternoon for the 4th time. Always need a breaker bar to get them off.

Original bolts - I clean them on the bench grinder with a metal brush attachment then apply a liberal amount of thread sealer blue to the last inch of the bolt and torque to 115Nm.

I've got a collection of new bolts that come with various parts but none of these new bolts are near the quality of the originals.
I just make sure that any new bolts are not a higher strength grade otherwise I will use them. ie if my original bolts are grade 10.9 and the supplied bolts are 12.9 I'll use them instead.

I do not reuse nuts if they are the kind that make their own thread for 'once use only'
