I appreciate your input - my phrase "piece of bent steel" was a bit
light hearted and has upset a few people - sorry. I do appreciate the
importance of the clevis bolt [and in fact every piece of suspension].
I was simply basing my recommendation on the Lola design which has stood
the test of time for over 1/4 century now [up to and including F5000 and
DFV sports racers] and which we have replicated several times. At one
time Lola went to a one piece machined from solid clevis bolt but
quickly reverted to the fabricated design.
One very important element of the Lola design is that the bends in the
steel have a radius and are not sharp corners [which would of course be
I'll be taking a look at the first Titans I can this spring!
I do agree that if you don't know what you are doing on suspension parts
- then don't.
