Where does one look for a place that can way a car?  I know if I had a train, I would go to the railway station, but where do you way a car - perhaps on a highway? 

Seriously, I'd like to weigh my Speedster - just curious to get an exact weight per hp figure.

Yeah, but if a race shop weighs it, it'll take you half an hour to wipe all the drool off of it.

Any place doing commercial weighing, like trash recyclers, truck stops, etc.....If they have a public scale it must be certified as accurate once a quarter by your respective government officials.  They're usually pretty accurate.

Or you could cajole Danny P. to bring his corner scales back to Carlisle and we can all do another weigh-in.  Personally, I'm about 30 pounds lighter than the last time he did us.

Not sure I would really venture out on a corner weight set up unless I knew the shop was really experienced setting up 911's as it seems rather complex for the normal front end shop. 

In all other situations I would probably make sure the suspension points on the Front 911 suspension are set equally to center before I have the car alignment done. 

Ray, you're seeing this as way more complicated than it is.  

You weigh the footprint at each wheel and THAT tells you volumes about the stance of your car.  From that, you can determine where to add or delete weight at the car's corners (each wheel) to get your car balanced as you want it for the application you point your car towards, meaning, how it will handle under specific circumstances.  The weight balance for a drag car is a LOT different from a road course car and from an oval car.  The set-up of each is based on a lot of real-time experience of lots of racers out there and is relatively easy to induce and change (if you have adjustable suspension components).  

If you have good suspension design, these weight balance tweaks can be done very quickly (watch the NASCAR guys giving a corner "a few turns" in the pits - all they're doing is adding/subtracting weight from a specific corner of the car by increasing/decreasing spring rate on that wheel on a coil spring).  

All of this stuff is simple, once you unnahstan it, right?

Exactly!  

Or Weider weights, if you're into that sort of thing.......but sand bags are probably cheaper.

A quick change can be done on the rears (and diagonally affecting the fronts) by tweaking the pre-load on the rear wheels by way of cranking the spring plates on each side, if you have adjustable spring plates.

Lots of ways to skin a cat, Ray.

I drove Bridget onto the local dump scale on 8/19/16.  With ⅔ fuel: 1940 lbs with me behind the wheel, the tool bag, jack and tire iron in the trunk, etc. (That's roughly 1765 lbs. without me in it).

I'd love to get corner weights, or at least front-to-back weight bias, and also weigh-in with the bumpers, spare tire, top and windshield deleted (i.e. "stripped for racing.")
