Part 2
Corner weighting.
I use a simple weighing method, one sold by speedway to measure weights
at the track. Simple but has a lot of built in errors. It is temperature
sensitive, has only 20 lb graduations and you must use a shim to tell
when the car is off the surface which really adds or subtracts a lot.
And it dings the wheels so I had to fab up some more tools to alleviate
that. At the end, I was doing changes in front and rear coilovers 1/8
turn at a time. I found sticky friction to be an issue. Evry heim, every
shock has some friction in it and it will never come out exactly, at
least in my experience.
LF = 670 # RF = 660 # LR = 870 # RR = 860 #
The diagonal weight is LF to RR 670 + 860 = 1530 pounds
RF to LR 660 + 870 = 1530 pounds
Front weight is 670 + 660 = 1330 pounds
Rear weight is 870 + 860 = 1730 pounds
