i had a 1972 Holbay f3 engined twin cam in the early 70’s. what-a fantastic car that was in it’s day.
Always wanted an BDA . never got around to it though, so i do envy you that car.
i’m sure you did not need to know that, but i thought i would chip in with it anyway.
It will be very difficult to create a like for like scenario. but you must be able to achieve a “guess t mate”
of your expected lap time with respect to simulated times of others around that circuit.
then adjust surface condition ( slow , green , etc , etc. ) until you get near to the required lap time.
CM may allow more parameters to be changed. ( i do not use Content Manager ).
it’s a difficult car to drive, it certainly does not stick like the slicks suggest, they must have
Simulated for the rubber of those times! .
i doubt very much if it is going to be much quicker than your
car is around Zandvoort any way especially as you , i think , will be on modern tyres.
( not really sure when you are referencing your real car or to AC simulated car ).
