M5 is done. Picking it up over lunch.

They sent me pictures of the reinforcement done. Needless to say the bracket should now stay put.

Awesome
nice welding job, as far as ive heard, aluminium welding is quite specialized and not every welder can do it... its all good. Enjoy


and thanks for the sharign of all the pics, now myself (530d e39) and others (540i e39) etc can look out for stresses....

I think I am going to enjoy it with a feather light foot for a while.

Haha I understand..... :rollsmile:

You can then enjoy her gently :tiptoe:

Did they give any indication of why it failed? I am a little worried as my M5 was driven for a while with collapsed diff bushing and I am sure it took some hits!!

Apparently the diff seals were done a while back at 3 series service center. They overtorqued the pinion bearing which caused the damage to the diff and possibly caused extra strain on the mounting point.

But the mounting point is aluminium and the M5 has a lot of power, so it's a weak point anyway. That's why DINAN makes a reinforcement kit.

interesting indeed.
i think what alot of mechanics (which these days are often "fitters") dont realise, behind manufacturer torque specs theres some science, different metals mating, expansion and contraction etc... why certain types of bolts are used and why they are torqued to a spec which allows for variances in temp,expansion/contraction etc etc...

There are times when I think I might be getting over the e39 M5, and then I see a picture like this and realise, I'm hooked for life.

Beautiful E39
Lovely colour,

I just bought me one and I will be following your thread closely.
