Don't wanna judge you. You doing what lot of peoples doing or just repeating them and like they don't know lot of things "behind scene".
Without any advices,but assetto-db - old leaking/sharing source, which (seems still continue) compile quite old/outdated (may be some new) and etc mods.
It's every time not good to see, when peoples using outdated or unknown versions from Assettodrive, which also can be broken or deeply changed.
Soon AD kind of birthday (seems to be about 5 years) and time for renewal of domain and services (let me try to make you understand, that such behaviour, like shown by you - for all this time doing this period "a little bit" harder..).
Let's not go deeper in this topic, but as modest "gift" will share there last available version of 918 Spyder roadster
.
---
What is there:
Suspension geometry is similiar to KS 918 (setup, including springs rates and mostly all - are different). 4WD configuration like in KS release. All else (almost all) is custom (from 2015 release and updates). Car feels in another way and shortly can be described, as more "gently" or for "everyday ride like". Be patience, this one is going with one LOD and this is high poly model (about 400-500k polys). This version also going with extension file for CSP (Custom Shaders Patch).
You can save this link, be cause when/if any update will out later - it will be the same:
Pass:
assettodrive
Honestly, not best example from list of released cars, but it's good enough to enjoy it physically, aesthetically and hope, that you will too ..
Best regards.
