The Vice bar seems an interesting option.

Would it need to be done with reinforcing plates? And resin as well?

Also how much does it cost and were do you buy it?

Does Redish provide it as well?

Kind regards,
Alex

Hi Alx,

We (Redish) can help you with this if needed.

If going for the VinceBar, it's also worth improving the structural mounting points (under the car) of the Rear Axle Carrier Panel.

I'm not sure of the exact price of the VinceBar as it's an American product but he's on m3forum.net, as Ejaz just mentioned.

Over the past 6 years repairing E46 RACP's we've completed 8x CSL's (and approx 140x standard M3's).

The other thing to look out for is the internal cavity mount spotweld and cracks which are becoming more common.
These are even harder to diagnose, and go on to repair, than the underside of the RACPanel as they are hidden in cavities only accessible inside the car.
Check out this 49k 2004 M3 from last week:

If you need any help or have any questions just let us know and we'll be more than happy to help.

Best regards,

Thank you for your advice, James.

As I said before, if you were not this far from Switzerland, I would already have taken my CSL to Redish.

Maybe we will find a solution in the future? ;-)

My independent mechanic is quite familiar with the CSLs and he regularly checks the car.

His advice is to reinforce it, but only once the cracks appear.

Very few cars seem to suffer from this here apparently. Maybe this is due to the roads or to the fact that we are too far from the racetracks...

I will keep following this thread with great interest.

Kind regards,
Alex

@Alex
Plates + Stiffer Bushings is everything you need. Forget the vincebar, its way over the top and intrusive. I personally wouldn't consider buying any car with such an invasive install done.
I would die a little inside if i knew that a CSL was ruined with this.

If you are thinking about going to these lengths, at this point just get a half cage tied to the struts installed.

Thanks to James Redish for dropping by, i think we all can learn alot from you in this department.

I have to admite that Vicebar looks way ott. Each to their own I guess, but as Select said its incredibly invasive.

Alx, If your car does not currently have a crack you may consider injecting the resin as a preventative measure.

I considered the resin, bit I didn't find anyone in my area that does it.

BMW says that they don't do it anymore.

I also read that it makes it difficult to weld afterwards as the resin is inflammable.

My sons had his welded up by BMW with the resin in, BMW wouldn't redo the full panel again, foc Will have to see how this pans out.

Interesting..did you ask what is their way to resolve the issue? Im guessing they would just replace the Bootfloor for the thousandth time? I might just ask my dealer what they advise, just out of curiousity.

Yes, that is correct it will melt and eventually catch fire. I'll have a look, as far as i know BMW released a bulletin regarding that concern.
