Lovely little proto! Really nice seeing some of these more obscure historic cars.
Besides the very low default FFB, I just wanna bring up some things I noticed regarding the physics.
Since these cars used vintage grooved tires, make sure to use the standard short names for them so CSP auto generate water displacement physics correctly.
In this case it should be SHORT_NAME=V... This way CSP will understand these tires are grooved and guess the correct values for water displacement. The way its set up right now CSP is assuming the tires are slicks and is generating a separate compound. Basically, if you use any short name other than "=ST" and "=V" CSP will guess they're slicks (including V60, V70 etc) and generate a separate "WET" compound (which you don't want in this case).
Also, speaking of tires, in my opinion they're a tad too grippy. At least in comparison to aphidgod's Lola T70, which is probably the best proto mod to use as reference. I'm basically getting a similar load sensitivity curve to the Lola's tires, which, afaik, are very much wider (beware he's using a .lut curve for the Mu, so the Fz0, dx and dy lines in the tires.ini aren't applied. E.g. his is actually 1.36 lat Mu @ 1000 load for the front tires, I'd say yours should be quite a bit lower).
As for the suspension, you can't go wrong with using the DWB
anti-squat/anti-lift bug fixes. Basically, just add these lines in the suspension.ini:
INI:
[_EXTENSION]
TORQUE_MODE_EX=2 ; antisquat fix for new trailing arm geometry
FIX_PROGRESSIVE_RATE=1
USE_DWB2=1
Last thing, if you decide to update the tires, i'd highly recommend you to take a look at Cphys new thermal model which is a lot more accurate than the default KS one. There isn't much documentation on it, but you can find bits and pieces of information on
Arch's physics pipeline, the CSP discord and on some mods that already use it like the NSX and aphidgod's Subaru WRX here on RD and some recent RSS and VRC mods.
