That actually makes sense. Thanks... I'm already working on returning the two prothane ones.
I didn't actually have a problem before but since I'm upgrading everything else I wonder if I'll have a weak spot. I'm N/A right now but have every bolt one known to man and will be going with a S/C in the future.
Anyway, do you think I'll be safe using the OEM stuff or should I upgrade? If the later, what are my choices?
