Awsome mod! but here a suggestion, when you included a stig in your mod, it won't drive since the stig mod is outdated, and even when you both delete the car, and the stig, you're still screwed after redownloading the car, causing a fatal vehicle exception, this happened the same for the BMW E30 M3
For the Lancia, try deleting the lua folder inside Mods > Lancia Delta Intergrale > vehicles > delta I believe the E30 may need complete repackaging or something along those lines, don't take my word for it.
I changed Rally version a bit as it was too nervous bunny for my liking, shorter diff ratio for gravel rallying, not sure if it destroys other versions of car. Engine could use more work, turbo spools too fast for my liking, but several options are unexplained and no information could be found, I did read real car data and tried to aim for that, but I would need to find a lot more documentation about parameters in jbeam files in order to make it anything properly real like, too many unknowns, I have no idea how to get front/rear drive split of 40-60% to 50-50% of real car. rc.sbeam had sound maximum rpm set to 15000, I set it to maxrpm and it sounds more proper, not sure if it still is right, but better. Author of the mod, give it a go, you can see from file how I made delta engine and delta intake, so you can have better naming for stuff, I like this version better way how it drives, but of course everyone has different preferences, I think it is improvement, but that is just my opinion. I don't recommend others to go and install files, if author of the mod chooses to put those changes in mod then everyone would have same version of the mod instead of many hacked versions, but everyone is free to do as they wish of course. I just did this for my own enjoyment and though I share my first test of altering a vehicle in this game so that maybe author can improve handling, so don't murder me.
hell yea. just YEEEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAA BOİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİİ oh crap, fatal vehicle expection!!!(nooooooooo!!!)
Small update: Added new file "Delta Hotfix" to the main page to make the vehicle work correctly with 0.8 (Lua fix by darren9)
In My opinion, this is BY FAR the best Mod to come out for 2016, Excellent Jbeam Quality, Excellent Meshing, Configs (IMPORTANT) And the fact is you hid a easter egg to. Everytime I see this I Clap in admiration for how much effort you put into this, I also cant wait for youre Volkswagon.
I like this mod and I think it will be nice when you make a lancia rally 037 Martini San remo from Walter Röhrl
