Good points by both ERA 2076 and Era Charles .
There is a relationship/goal that the suspension guys I know use for initial setup for track cars . The left side tires should have the same front to rear wgt distribution as the whole car and ditto for the right side . However , please note that the LS and RS actual wheel weights may not be the same because the CG`s may be offset .
So , just for the fun of it , I put ERA Charles` weights into my formulas to see how close his car was to the "ideal" setup . Pretty close .
Charles .... per my formula , you should be at : RF @ 656 lbs , RR @733lbs , LF @ 675 lbs and LR @ 762lbs . Your actual weights were RF ... 648 lbs , RR ... 748lbs , LF ... 682lbs and LR .. 755 lbs . The rule we use is , if you are within 10 lbs of the goal , don`t touch the car until you drive it . 50 lbs off , you readjust .
FYI .... my weights were all within 1 to 3 lbs of the "ideal" and the car handled great on the track . Note , I said on the track . I will bet you that a car can be off 50+ lbs and the average driver will never notice it . Also , tell someone his car was off and then say you adjusted it and I bet you he will say it handles better . We did this several times to drivers when i was doing dirt track .
I weighed/adjusted my car because : I was going to track it and I had replaced all shocks and springs and the ERA settings didn`t necessarily apply anymore for the heavier springs . They got me in the ballpark for the street , but not where I wanted to be for the track .
BTW , my suspension guy has over 20 years setting up dirt cars , SVRA , HSR cars and NASCAR truck series trucks .
