Why do you need strut reinforcement plates on an E89?

I’m not aware of any cracking or flexing issues on E89s?

Just for added strength/protection!

I’m changing the front struts to oem bilstein B4 and wanted to add the reinforcement plates for good measure! I can’t find them for the E89 frame, Everything else but????

Make it stronger and protect it would be my guess...

The E89 has a much stronger chassis than the E85 where tower strut problems were commonplace ..deflection , cracking etc

AFAIK there are no support plates on common sale …if you are worried you could add a strut brace like Weicher across the struts that have substantial tower plates …

I’ve got one fitted although I can’t say I noticed any effect / improvement from its effect..

Bimmerworld did quite a bit of research on this and came to the conclusion that even on a track the later design of strut towers with their bracing were good…FWIW

Thanks for the info!! I do believe all the info I have reviewed on the strut plates were on the E85 so I guess I won’t worry about it! Save me a little money and additional hassle!!

Front end of E89s are very different to E85…back end are quite similar..
