This question came up over on the Cobra build forum---what grade bolts to use as replacement on a suspension piece. A big debate then ensued with many people suggesting that Grade 8 is always superior to Grade 5 in every application, in short that is a superior bolt and the only reason to use grade 5 would be for lower cost where higher strength is not needed.

Are there any applications on a race car where one would not use grade 8 because of its brittleness? Are grade 8 bolts more likely to fracture rather than bend?
Thanks
