Can you explain why you must have new bolts. That is one of the areas I'm still unclear about when it comes to all the M3 control arms, both front & rear. Some say you should, Bentley says replace (at least for front arms, rear I haven't found yet) but most haven't replaced them (that I know of).

I really would like to know exactly which bolts/nuts should be replaced and which not for the front & rear control arms. Oh, and torque specs too.
