Don't take offense, I'm just surprised. I spend most of my time dealing with P-cars...most of them old, and none of them with really heavy transaxles.
That said, my Spec 944 car should weigh ~2600 lbs with a full cage, all of it's original glass, and steel body panels, with essentially only a stripped interior.
I know of 60's era 911s with glass fenders, doors, hood and running with a rollbar that hover around 1800 lbs.
I'll be putting together a 76 911 race car (GT Limited, for those of you wondering) with a 993 carbon fiber body kit and full cage...I'll be disappointed if it weighs much more than 2400 lbs. Now obviously, it won't have a v8 in it, but an ally block v8 won't weigh THAT much more than a stock 968/993 motor. I'm sure the Recardo will weigh more than say, a G50 etc, but how much? Maybe 75-100 lbs.
Obviously, again, not apples to apples. The cars I'm talking about have been stripped to the bar minimum...and at least some of the SLC's are fairly well appointed street cars. I suppose "the little things" do add up. More than I had imagined.
Hey Ron, love to see your 911 when finished, good luck with it.
Vehicle weight is one of the most important aspects of performance - sometimes.
Having a balanced vehicle probably is more important.
It's easy to start focusing on one aspect of performance, and get out of balance overall. Having 1000hp in a SLC i'm sure is a thrill, but makes the car virtually undriveable, even in a straight line.
Tires are where you should start when looking at performance, as they are the biggest factor, bar none. Tire compound is very important on the track and on the street. Most tires are engineered for a vehicle weight range that most cars fall into, usually over 3000#. To get the best performance out of the tires requires getting heat into them, this is where a heavier car may have an advantage, as we run the soft Hoosier A7 compound, and still see lower tire temps than recommended, until we get over 80-90 deg ambient temp. You can run softer compounds, as long as you like buying a lot of $tires.
Weight distribution is just as important as total weight, to match your tire package, for a SLC, somewhere around 45/55% f/r matches the tire sizes most people have. You also want your aero balance to match your weight distribution also, so your mechanical/aero balance is consistent.
We race against a lot of Porsche GT3 Cup racers, not sure what they cost,
but I can guarantee, they are more expensive to own and race than our SLC!! IMSA sets the weight for theses cars @ 2650 race ready without driver, in sprint racing trim.

We raced a Cup car at last years 25hrs of Thunderhill, and were 5-6 sec a lap faster in race trim against a Factory built racecar, as compared to our home built kit car. Rumors abound about their budget just to run this race at somewhere around 1-2 times the value of our SLC! (We used about 9 sets of tires for this race)!
