Think I'll get this done when I'm up there for a service.Sounds like good value if it does stop the cracking.They will probably all crack eventually,except for the garage queens

this is just a prevention not a cure. my personal view is wait until your car is roughly 3 months off the 10 year cut off point for goodwill/new floor replacement. get it checked if you get the all clear get the injection done. most of our cars arn't ten years old till next year so your worrying about it slighly to early

If you havent done it, do yourself a favour and get it done, even if there are no cracks, its a huge mission to fix it if its too late.

I repaired my cars cracks this week. I think the floor should have been replaced but due to lack of skilled workshops and because I couldnt find anybody around here that has done it, I did it myself.

I got the turner plates and I did the Structure/cavity foam. Drove it with the rear seats out after letting it stand for 30hrs and heard a squeek (another crack below the rear seats) welded that up and finally its solid again...

I wish I just did the foam before all the cracks. If one mount fails it puts huge preasure on the rest untill they also fail....
I have pics to prove it.....

Left rear mount

Right Front mount

Left rear

right front

After welding

After sealant and Primer

Inside cracks where squeek came from

I am also going to fill cavity's right under the inside weld with a hard rubber compound just to be safe.

Interesting

I posted a thread on cutters as im in the process of preparing the car for a few trackdays.

The Gist on there is that perhaps the Resin isnt sufficient? And is no longer BMW's answer,

Has anyone run the Resin only for a significant period of time including some trackdays to see if it holds up?

Niel333 · 11-06-2012, 11:24 AM

If Bmw does the resin after they replace the axle carrier then I suppose its a good way of preventing it in the first place.

Its good to see that by welding the cracks makes it as strong as before, but its the rust that worries me because all the rustproofing melted away with welding. With the reinforcement plates also welded in, you wont see rust untill its way too late....

I just filled as much cavities as possible with the expanding foam... Dont know if it will help!!

Sounds like the best case then is catch it before it happens. expoxy the plates on and fill the cavity with foam.
