[Land-speed] Car Spins

[speedtimer at beyondbb.com]

I have seen probably more spins from the timing trailer at the lakes and 
salt then anyone. Over the years one can tell when a car is in trouble and 
if  it in our visible area. I have seen them spin under every condition and 
reason. There is never in most cases when it will happen or where. In 1957 I 
spun in the 5th mile driving a rear engine modified roadster. Wasn't any 
thing I did, the crank broke and locked up the drive train and it went round 
and round. I have seen cars spin because the driver turned out to fast and 
lost it, I have seen them spin at the lakes because of cross wind and 
getting a wheel in a rut. Being over aggressive, wheel spin or just a bad 
handling car. It's the repeat problems with the same vehicle that worries us 
and we take steps to work with the owner/drivers to correct it.

Every run is documented. At Bonneville and the lakes we have people that 
look into everything we report as needing action. They have years of 
experience and will work with you and in some cases put you on the trailer 
if necessary. It doesn't happen to often but is does happen. If there seems 
to be a problem get the chute out first and in most cases it will save a 
spin or worse.one rotation will ruin $1400 in tires. Common sense will be 
your best friend.
