[s-cars] Follow up on Spacers

[ccohen5]

Thanks to everyone who responded to my request for info on what and where to
find these.  Seems that 5mm H&R is the preferred product and
http://www.ecstuning.com/ seem to be the only place supplying over the web
although 2 Bennett and others will supply based on a phone order.

An important thing that no one mentioned but I picked it up from ecs, is
that the bolt length needs to be able to accommodate the spacer.  I think
5mm will not impact the integrity of the bolt, but I am going to check.
There is a formula in aerospace that says at least half the length of the
bolt should be in threaded contact with the female part of the fastener
without requiring special materials to compensate for high stress torque.

A friend of mine drove a '70 Mini for three years with only 3 of its 4 bolts
on the front LH wheel, and one of those was finger tight.  Said he never
noticed a thing!  So in all probability this connection point is over
engineered!
