Abarth 1000 Berlina 2.0

Finally after so much time, books reading and questioning around I have been able to update this tiny beast to version 2.0.
In 3 year many things have changed in the world as in the modding community.
First of those is the introduction of the Custom Shader Patch made by Ilja Jusupov aka x4fab that is now required (you can easily find it on the web) for the car to work. I consider this patch as a natural evolution of AC in which it improves (and sometimes fixes) the yet optimum Kunos engine and adds many interesting graphical features.
Reguarding the car, it would be useless to make a changelog since almost everything is changed, including the folder names (so you can delete any previous version you could have [or keep them as a memory of the past ])
Basically I tried to bring to AC every versions I could find good technical info about, starting from the power curves...
For this reason I'd like to thank some of the authors of the books I bought in these years like Gianfranco Bossù for his various Radiografia Tecnica books (Abarth engine technical analysis) and Aligi and Elvio Deganello for their interesting Abarth book with technical data, modifications year by year and drivers' interviews about the cars handling.
Thanks to Frank de Jong (RIP [2018/05/10]) that collected everything he could find about the history of touring car racings, including lap times so that I could match them with the available historic tracks.
And always thanks to Angelo Granata that gave me permission to use his 3D.

When I started this project the first time I didn't have much references for the various versions of this car so I just built a base model and some upgraded ones that matched the technical data I had then.
Now, instead, you'll find 6 cars (with mixed skins, thanks to the community for some of them) divided by year and with a FIA classification in the name.

A brief history:
- 1963 Berlina Turismo:
Abarth introduced the tail lifters in the back to improve the aerodynamic efficiency and reduce the rear lift
- 1964 Berlina Corsa Gr. 2 Class 1000cc:
This was the first Abarth 1000 homologated car, it had the possibility to have 5 gears transmission (still 4 into mine) and brake discs in place of drums
- 1965 Berlina Corsa Gr. 2 Class 1000cc:
Lowered setup for better stability was installed and an LSD was abailable in option like the 5 gears transmission. On front 2 "helper" springs substituted the rubber bumpstops and bigger 4.5 x 13 inches rims with fatter tires were homologated
- 1966 Berlina Corsa Gr. 5 Class 1000cc:
In 1966 Abarth finalized his "Radiale" engine head, an hemispherical combustion chamber that allowed, thanks to a better efficiency, to overcome the 100 hp/liter. The term "Radiale" really has nothing to do with the head but when the engineers were thinking to a name for it late in that day, a collegue came in the room asking if they wish to do a Radiale in Turin with him after work. Radiale was a way of saying for "take a ride". Unfortunately this head couldn't be homologated for Gr. 2 so this car competed in Gr. 5. Moreover, the front transverse leaf spring could be abandoned for the "Pendolino" system (basically a lower A arm) that made the front a fully independent suspension with coilovers. This system had the advantage of a certain degree of adjustability but lost the Anti-Roll bar effect that a transverse leaf spring has.
- 1968 Berlina Corsa Gr. 5 Class 1000cc:
Still within Gr. 5 because of the "Radiale" head, this car adopted a different geometry for the rear trailing arm, they called it "Pendolare".
It has a lower Roll Center that helps the car to manage its natural lift off oversteer behaviour and allows for a further ride height reduction also thanks to rear coilovers. It is responsible (together with chassis poor torsional stiffness that, sadly, can't be reproduced in AC) for the odd behaviour of significantly raising the inside front tire.
From 1967, moreover, bigger brake discs were available.
- 1970 Berlina Corsa Gr. 2 Class 1000cc:
Radiale for all! In 1970 Abarth finally homologated the Radiale head for Gr. 2
Main difference, here, is the power that increased up to 112 hp, enough to reach 200 kph, almost doubling the maximum speed of the starting FIAT 600!
This was the last official update from Abarth since from 1971 FIAT bought Abarth and dismissed his race involvement.

So, I hope you enJoy these babies as I did while searching info for them and, if you appreciated my efforts and wanted to offer me a beer, here is my Paypal link:

In this updates you will find some minor fixes and, on a fan request, a Slalom Prototype version of the FIAT 600. This is just in an early WIP phase since there are basically no information about it. If someone hase some data about this car or similar one...

Hi folks, I finally had time to update these little babies. Since so much time is passed, I changed many many things thanks to the gained experience, new data found and AC updates.
From power to suspension and to the skin liveries and previews (thanks to the Content Manager)... all is changed... and I hope in better.
The Berlina can challenge the 595, the Gr. 2 is sometimes slightly faster than the 595 S2 while the Gr. 5 can compete against the Alfa Romeo GTA.
Enjoy

Very small changes to damping model and a little but significant change to inertias that make the cars more reactive on front axle as they should be, being them rear engined cars.

As title says, I corrected a little the Fuel consumption and wheel travel in suspension.

I fixed some values related to wheels travel and made Berlina and TC Gr2 more understeery or safer...
To reduce understeer you can also increase front tire pressure.
Last but not least, even if coast power in such small engines is not so high, I introduced in an experimental way just in Gr5 TCR the Engine Braking Setting: Now with CTRL+4 you can increase your engine brake while to decrese it you can cycle the settings or press CTRL+SHIFT+4.

As title says, v10 tyres and brake heating model have been implemented.
Moreover Pitstop repair times were added

Hi guys, after all this time I made some more experience and got some more specifications so I updated the 3 models from the suspension geometry to the springs and dampers. Again, due to the huge rear weight balance and to the fact that TC and Gr2 used same tyres front and rear, I added some challenge to them.
Gr5 is safier but fast and brutal as always
If you want to correct off throttle oversteering behaviour, I suggest you to deflate front tyres and inflate rear ones...

New more competitive AI and revised fuel consumption

I finally had time to check the stiffness of a rear leaf spring on my FIAT 126 so to have a better idea of those spring values. So update reguards springs, dampers obviusly are adapted, and some minor fixes to power and suspension geometry.
Now also the simple 1000TC should be funnier to drive and can challege with 595 Step 2.
Hope you enjoy

This time I want to thank my friend peksis that fixed again the collider box. Now the car should run fine over irregularities.
A little fix also on downshift timings.

Increased FFB

Tyres are updated to version 7 and some improvements are done taking inspiration from the new Abarth 595 by Kunos.
Unfortunately the 595 sound cannot be used since the 1000TC has an higher rev limit and I'm not able to do sounds

Thanks to DTM1120 for its fix to collision box.
Secondary modifications to collider, drivetrain and gearshift animation

Fixed Colliders to improve collision between undertray and roads

Little fix to center of gravity height and inertia

I got more info about old damping models so this update is for dampers

As title says:
- Fixed differental values for the three cars with more realistic ones
- Fixed Steering Ratio for Gr2 and Gr5 since new information was available
- Fixed Springs and Dampers for Gr5 with stiffer values to improve track feeling

I updated the spring and damper model to make the cars a little bit more aggressive and maybe hard to drive but more realistic in my opinion.
FFB is changed too

Fixed steering ratios and Ackermann angles to more realistic values and now Gr5 has a different steering ratio.
