track and flange to flange

[Dominik]

here are the measurements to get to the flange to flange distance:
25.4mm = 1"

the values stand for:
hub + gap to upright + upright + balljoint mount + control arm + length to chassis CL (no disk!)
the 6-pin wheels stick about 20mm more out in front than the 5-pin (TRIGO), so using the TRIGO one could make the front control arms 20mm longer, AS WELL AS the tie rods of the steering!
(depending on the body to use)

front lower:
8.5mm + 20mm + 53mm + 15mm + 277.25mm + 330mm = 703.75mm x2 = 1407.50mm (55.41")
front upper:
8.5mm + 20mm + 53mm + 55mm + 252.5(?)mm + 311mm = 700mm x2 = 1400mm (55.11")
(we want a little less for the upper to get about 1 deg neg camber, see below)

upright height = 230mm (but add balljoints), KPI 9.8 deg
where is the vertical distance from UCA (upper control arm) to LCA to get a feel for IC (intant center) and RC (roll center)?

I am not sure about the length of the UCA, because I do not have the length of the camber adjusters, so I calculated it using all other values.


rear lower:
8.5mm + 10(?)mm + 101mm + 315mm + 234.15mm = 668.65 x2 = 1337.30 (52.6")
rear upper:
8.5mm + 10(?)mm + 93mm + 290mm + 260.8mm = 662.30 x2 = 1324.60 (52.1")

the uppers add up to about 6mm shorter than the lower, which is 1 deg negativ camber at the wheel, because the upright is about 315mm high.
the 10mm gap hub to upright rear is a guess, because I haven't finished one to orig specs yet.
