Subframe Poll

So how do BMW do the fix and can you tell if it has been done by looking at the car?

Easy to tell, finished in shit undercoat

Based on what evidence? My repair was excellent.

Had mine inspected & no signs of any cracks though it does concern me to read where some garages have misted them.

Mine is just about to turn 34K & had Intrax suspension fitted round about 21K.

Perhaps a stupid question but does the Intrax accelerate the process or does it transfer the stress elsewhere? Or make no difference?

Tbh nothing seems to make much difference. I think others have said its the diff stress onto the subframe mounting points that starts the cracking.

Intrax rear coilovers can cause other cracking issues on the turrets so make sure you get rear and maybe front turret strengthening bolted on (OeM simple and cheap plates)

Based on the shit dark grey finish
The replacement is spot on, it is just not sprayed as it came out of the factory.
It was done at Elms so I presume the finish is the same on them all.

As I was closing the computer down last night I thought torque from the diff could be the main offender.

I was going to fit reinforcement plates a few years ago on the rear Shimmy but I asked Simpson’s to do it & they said they’re not required & I took their advice & didn’t bother?

Honestly ?? And did Elms sort?

I will be getting it painted, at some point...

When the goodwill work is done you have to be careful that the lazy b'stard body shop actually replace the whole boot floor.

Some of them cut the repair panel in half and only weld in the diff carrier.
