I might be interested in some Ti bolts for unimportant parts.
I had a bad experience with a Ti seat bolt on my mountain bike. One morning the bolt snapped and one end plus the bolt went flying when I sat on the seat. I only had it on for about a month. Perhaps it was defective or i overtorqued it or i exceeded the weight limit.
If Ferrari uses Ti wheel bolts, I imagine they must be more than adequate. I should check out the ones on my friend's new f430.
