Tarantula rims, Magnesium?

[green536@hotmail.com (Chris DeLong)]

Larry,

While your argument may have some validity it still does not hold ground. If 
you would argue that NO PART is cast from pure Magnesium you are correct 
(AFA VW car parts go). However, this would not explain how Aircooled beetle 
case shavings (some Magnesium content but mostly Aluminum) ignite with a 
very intense white light. These shavings can be ignited by a mere cigarette 
lighter. They burn by themselves.

Tarantula wheels however have NO Magnesium content. If there is any 
Magnesium in them it would have to be so miniscule that the entire wheel 
could not possibly be considered as a "Magnesium" wheel. Not even a spark 
came from the shavings we tested.

Tom's wheels from his porsche could very well have a high Magnesium content. 
I have worked on many Porsche's and the first time I took a wheel off of one 
('77 911) I almost threw it over the car anticipating its weight.

Now can we PLEASE drop this dumbass thread?
