A6 2.7T Improvements

[Peter M. Clark]

	My 2000 A6 2.7T is currently sporting the stock sport wheels with 205/55-16
performance mud and snow tires I put on for the winter months.  Now that
Spring is here, I am considering some wheel, tire, and suspension upgrades
while I switch over to summer tires.  I would like to receive opinions from
other owners as to the pros and cons of the following:  (1) upgrading to a
17" wheel and tire or an 18' wheel and tire;  and (2) installing a
performance spring and shock package.  I live in New England and I am
concerned about the effect of a lower suspesion set-up in the winter when I
go back to the winter wheels and tires.  Given that I may only get the car
on a track once or twice a year, are these improvements worth the effort?

	I am also curious about an enhanced performance chip for this engine.  I
would be most appreciative to receive feedback as to the effectiveness of a
chip, any problems associated with it, and where to get one.
