Uprights
Because I can only define "half upright length", it is not possible to replicate the 49's geometry where the front upright is very "top heavy" and the upper ball joint falls outside the brake disc diameter and the lower within the "cup".
Initially I thought this would only affect the physics in camber gains which I could recover in other ways. As I learned more I realise the bigger effect is in relative roll-centre heights which are critical to handling balance.
The obvious difference is graphical where the cowling on the body needs to be lower so I can't quite get the nose shape the same. And because I wanted the same KPI of 12 degrees (to keep a reasonable scrub radius) the lower ball joint sits within the actual disc. I have tried to hide it but it is a bodge!
I thought rear end would be less of a problem but the packaging is very tight around those exhaust headers!! (TBD)
Pivots
On this and other cars the rose-joints at the inner end of the wishbones are at different widths which is not an option in LFSE.
Correct 3D positioning of all suspension pivots would obviously have some physics implications. Graphically, there is a big impact in packaging in tight areas - in this case there is a lot going on with suspension arms, drive shafts, shocks, exhausts, all in close proximity. Luckily my shocks are invisible
Tubes
Because some of the arms on the 49 are pressed and some are tubular it would be better if oval / round was selectable per tube.
It would be nice if material colours were available for the suspension arms eg. black / white / chrome or even better full textures.
Imagine if a thick tube could be added between thrust bearing and lower upright you could texture it with a spring and the whole thing would expand and compress as a simplified version of a coilover.
Additional
If you could define points in special draw that move with the upright then things like steering arms and anti-roll bars would be possible.
Improvement Suggestions
- (MAIN) Definable upright geometry (eg. lower length & upper length)
- Roll centre heights displayed on the suspension diagram
- Full 3D positioning of inner wishbone pivot points
- Oval / round selectable per tube
- Material selection for suspension tubes and eventually texturing
- Definable points that move with the upright in special draw (not just the default three)
