Not sure if any of this is useful but just in case:

Thanks.
Is it possible to build chassis from these data?
Chassis specs probably one thing that is missing for continuing working on this alfa.

Yes I believe so but I'm not really the right person to ask. It sounds like you need to tame a physics guy to help you out. As far as I know you can use photos to get more or less the right suspension geometry.

I haven't done much research but while I was searching for the above links I gathered that there are some differences between the road going Giulietta 750 and 101 Spiders but I don't know which you are making. I don't know if there were any differences in the 1.6ltr Giulia suspension, same for the SZ. I also don't know how different the race cars were to the road cars.

I think these photos are clear enough to get a lot of measurements for the front suspension but again I don't know if the setup is different on this model to the one you are doing.

This link suggests the SZ is based on the 750 Spider chassis with Sprint Veloce components.

Wow! That's some very impressive research, @Andy-R There's some invaluable information there, and it also makes for some really interesting reading

Yeah I've never found anything this good before (I would go with the values for the car without the lower wishbone adjustment that he can't use because homologation.)

 

[Andy-R]

Still digging. I changed the dyno link, this guy used a 1.6ltr engine and a 1.3ltr race engine and I'm not sure which they had in for this dyno test but from what they said there were issues with the valves so they couldn't go beyond around 5600rpm, they expect 120-130bhp without the issue with the valves. I think 134bhp at 8K as suggested in the angelo chiapparini link below sounds about right.

This Spider weighs 1600lb wet according to the owner.

 

[Andy-R]

Sounds maybe?

You can also try the documentation department of the historic museum in Italy. They take a week or two to send an answer but they're very helpful and willing to send stuff. I received some info about the TZ when I messaged them asking if there was anything they could provide.

Thanks again, there's no goal to make concrete version, so specs can be vary depends of data. That's nice research indeed, i'll ask abbo again, hopefully there's would be enough info.

 

[Andy-R]

I think you could pretty much make the car just from that Ultimostile blog! Just needs the weight from a race spec Spider (1600lb-1800lb AFAIK) and gear ratios which you may well be able to get from a homologation paper. I could be very wrong though, it's coming from someone who doesn't know the first thing about physics modding. If I knew Abbo was doing it I wouldn't have provided anything as it may make the wait longer till the Griffith 200 is ready (only kidding.)

There are some chances that physics will be done for the merc, at least i've got motivation to unwarp and bake interior parts

Model turns more into a trophy car direction:

Are you still working on the SLC?
