lightweight mirrors

Thank you very much for answering, it's nice to have perspective from a track driver. Before your response and in trying to answer my own question, I looked at the owners manual for some numbers, listed below (for a base w/ manual transmission):

217 HP ;Weight: between 2777 lbs and 2954 lbs, which I averaged at 2866 lbs; 0-60mph 6.5 sec

Now I understand that these numbers are not scalable, but for giggles, if they were:
2866lbs/6.5sec=441 lbs/sec or 0.002267 sec/lbs.
Given 5 lbs reduction, that would equal just 0.01133 sec reduction on the 0-60 time, or with a car stripped of 100 lbs, an increase of 2/10ths of a second 0-60...which somehow sounds about right (at least to me)....

I should stay away from numbers, and stop asking questions.

Everything TRK is spot on (as usual!). 2 years ago I won a regional autocross championship by hundredths of a second. The top two of us (he drives a fully prepped 914) had equal points after 5 events, so the judges added up all of our times and I was a blip ahead. A couple of pounds may have been the difference!
Another great thing about removing weight is that it affects the overall performance: not only does each pound have to be accelerated, it has to be braked and turned. Less mass makes you faster everywhere!
