Not sure what the upper to lower a-arm ratio is… maybe try 800rf/700lf and go from there?

Front and rear have to work together by weight distribution factors! Total weight and percentages will give us a better way to help, along with what style of set-up you want to run! A nosed and hiking left rear or left leaned and roll to leveled out in the turn! I prefer the left leaned, as it is more drivable in traffic! If it weighs 2850 or 3150 is our range from 7-8 or 9-10 and front to rear percentages for the rear springs to work with the front! Spring compressed heights by pounds per wheel comes in to play with transfer when and where you need it! Leverage factors of locations affects rates of poundage change quickly!

its set up for a hiking left rear. right now I have a 180 rr spring and a 200 lr spring. 54.5% rear percentage with 90lbs of bite. the car came with a 845 rf and a 745 lf. but the car was once a swingarm car set up completely different to what it is now. people are tellin me the fronts are way to heavy and that I should drop it way down.... but nobody really knows where to go to. the car weighs 2505 with me in it.

Spring sounds close enough! I never liked hiking for it's ills! If leaned left 1" front and 1/2 rear with more angles on the right than left they should even out when rolled to help provide even traction! A150lbs. added to the left rear of the car will increase bite through the cross and response to bite as well as left side weight to stop the steer to allow getting off the corner straighter! A 200 split front with extreme caster will give the driver control of front and rear steer with weight transfer as the steering wheel is turned for control over track conditions and the cars momentum in the corner! A larger rear percent is needed to hook this type set-up but these pounds will speed you up and hold you in the corner when low and left! Any weight above gives roll and added steer to under-mind keeping your car straight as possible around the turn! a stiffer shock on the left ft. will allow a softer right to nose first and raise first to unload and steer just by lifting the throttle to turn on a dime as well as transfer weight back to left rear for traction any time you are on the throttle without hiking or transitions to get to 3 wheels to hook when nosed! A 5 left and 3 right with 3s or 4s rear! Straight valve shocks only to do this correctly! Read my other post to get a better idea of how this works to win with drivability and is a no changes needed set-up! Tighter or looser is in your hand and a turn of the steering takes care of it all!

Is this a Torino stubbed mod? If so I am helping a friend who has a wade moon converted to 3 link spring on top. We are using a 600lf 650rf 200lr and 175 RR 100lbs bite 55% rear 52% left. Left bar angle is as high as we can get it and left is 4° we have ride heights at 5 3/4 lf 6 rf 6 1/4 lr the RR is set by his much bjte you want. Car works well in the dry slick and is a little tight getting off if the track has some grip

We had a few different crown vic stubbed M&M Northern Sportmods over the last 5 years. I was usually around 600RF 550LF 200LR 225RR for springs. About 60lbs of bite. 56-57% tail. 52% left.
