What am I looking for and what does it mean when I do put my car on a set up board with scales? Is there a good starting point (left rear, right rear, etc.)
What you are looking to achieve, is the ability to return your
car to a particular point that was comfortable for you
after taking your suspension apart, or making changes.
Let's say that you start out with a LR weight of 350g.
And it's a little loose. By adding weight to the LR, say to 365g,
you find you like it. Now.. you have a point of reference.
If at the track some day, the car is too tight, you take some of that
weight off, and you may like that. By knowing how much you changed it,
future changes are easier, and more predictable.
But when you make spring changes, you can be off on your wheel weights
a ton... and then you really don't know it the results of the change you made
were due to the spring change, or a drastic reduction on a corner weight..
Another common percentage tool used is cross weight.
That is the percentage of the car's total weight, that is supported
by the LR and RF tires.
Generally 50% is a decent place to start.
If the car is tight, you may reduce it to 48%, if it's loose,
you can try 51%.
The thing with cross weight is, if you go to a new track,
and you have to add or deduct weight for their rules,
the addition/removal of weight isn't such a hindrence if you get your
cross weight back to what you like..
These numbers are to help YOU set YOUR car up the way that you
like it.
While there are 'ranges' that are pretty much universal, there are no
"it has to be this" numbers...
If anyone tells you that "it HAS to be this", you may want to check with
someone else...
