You can´t go after a Picture where the Pinny is parking backward. because the front going down and the back came up. there are parameterlists of Spring and pinion combinations in order of Vehicle axle weight. you should first drive on a weighting scale with each axle
so i look at your early P80 i would prefer you to take zwo line blue at front ( standart bolt, no lines) and two red/ one white (with 116mm bolt) at rear (for mostly full load driving). For front shock absorbers i would prefer you 716.1.54.103.2 series with spacers. stronger absorbers turns the halfaxles on the studs , especially on TD because wider track

I have also series on my armored 6x6 which has the weight on front axle like your hole Pinz!
For controlling of body to drivetrain by driving curves the front spring / absorbers are important, if "the back" is coming uncontrolled/ to early / or only one tyre contact -there is a fail at the rear air-system/ false springs.
at the back air system are two main groups of leveling sensor´s ,if you have a "anti-roll bar" to both axle- it is the first generation, which makes some times problem´s with the leveling way and often switch circles..
there are different typs of air-spring lines and diameters from 4mm to 6mm lines too.
may you can write why changing- where are the ( your) Probi´s? only changing to Koni or other#s is not a argument!
BTW the Pinz will never be a racing car, the driving condition´s are like a lorry

best like a light truck( sprinter, transit or co)
P.S. the ending tube of your muffler should by fixed at the chassis, because the oulet of the muffler isn´t strong enought for that! i have also RHD Ending tubes used for sale, also OME mounting plates for chassishttp://
