Front snub mount bracket

[jme1989]

Evening people 

New to the forum and have just recently picked up an a4 avant 

 

She has been mapped and egr delete has been done but in the last 2 weeks I have had to buy 2 new sn7b mount brackets because they have both snapped in the same position as the original one which is just in front of the single bolt at the end of the bracket 

 

Does anyone have any thoughts or ideas as to why this could be happening and also do they do a upgraded material like steel or anything like that other then ally because it is driving me insane and I don't want to just park her up she was meant to be my toy for the evenings when I Finnish work 

 

Thanks and appreciate any advice given
