Yes I can. I'm a degreed Mechanical Engineer with over 13 years
experience and have been a motorhead since I rebulit a 3-1/2 hp Briggs &
Stratton lawn mover engine at the tender age of 9. I would consider that a
bit of experience and training, wouldn't you?

They sheared out to begin with, didn't they? Take into consideration
that I have tons of horsepower and very wide tires on the car. All of this
contributes to the problem. I think that this _does_ address the issue.
You can replace whatever you like. It's obvious to most people that it
would make sense to replace them all instead of one or two.

I feel that if you will be autocrossing or racing your vehicle, these
replacements would be a good idea, not to mention a safety factor.
The Engineers and Designers of these cars designed for a much thinner tire
and not for the higher output engines. According to their 30 year old (key
words) calculations, the studs were the sufficient sizes for the forces
acting upon them. Even today, if you modify an automobile engine and
suspension, you will need to upgrade with aftermarket products.
>I want to undertand the engineering factors involved with this procedure.
I can understand that you do. I will not sit here and type in the
formulas and calculations necessary to prove my point. Some things are
derived from common sense.
You can install these inserts or not, I really don't care. I will be
installing them on my car. They are approved Military Standard products
used on all kinds of Military aircraft and I feel that they're just fine
for me too.
Thanks for your time.
