Contour Enthusiasts Group Archives Forums General Autocross and Open Track BAT 21mm bar?

I am familiar with the Aussie 23mm rear bar issue requiring boxing of the subframe (and some failures also I know with the old SCA 21mm). But I just noticed that the BAT 21mm bar advertizes that it "is the only bar that exactly matches all the stock bar curves so as to cause les stress on brackets"

So basically, any word on whether BATs bar has lead to similar bracket failures..??
