Metric grade 8.8 is roughly equivalent to grade 5. Go to your local fastener
store (not hardware store, fastener store) and ask for grade 9, or at least
metric 10.9 (equivalent to grade 8)
The upper A-arm bolts are under a great deal of stress, particularly if
you're using a lot of shims. You're just asking for trouble using low grade
bolts - you really don't want one to break, ever!
