Released as version 0.72

issues:
- AI too aggressive, very stressful to race side by side;
- Metalic paint show some strange shading of wireframe.

Changelog:

- added upgrades: engines, tires, aerodynamics, gears shifting mechanics;
- THANKS redapg for working well configured wipers together with windshields;
- THANKS redapg showroom wheels are displayed all correctly;
- THANKS hitm4k3er for many nice colors, and veh files and icons altogether;
- improved interior modeling and texturing and shading;
- improved various materials to pbr shading;
- added suspension low poly elements, barely visible;
- changed default engine to weakest;
- changed default steering to quick;
- increased default caster and increased maximum available caster;
- reduced unsprung masses;
- slight lodding distances improvement;
- rearranged and improved mirrors;
- new tires (experimental);
- overheating warning light working;
- wider graphical wheels + fuchs;
- reduced graphical offset of narrow wheels set in cockpit.ini(widened), affects physics;
- fixed small error in BodyIsoBallJoint (chassis stuff);
- added few custom final gear ratios;
- raised minimum pressures by 5kpa;
- lengthened steering arms inboards;
- upgrade option for no-clutch enjoyers;
- rear "wing" center of pressure moved closer to car center by 0.06m;
- steering arms lowered 1cm for less bumpsteer at front;
- altered rear toe links for minimal bumpsteer at rear, then brought little of it back.


Future dreams and hopes:
-bumpers: finish mesh and UV, bake AO again, add bumpers to template;
-blur for fuchs;
-few more interesting skin paintings;
-backfires;
-disc glow;
-oil temps gauge;
-model optimisations and polishing of some details;
-body rain descriptor;
-body-in and cockpit instances sort out;
-get AI to choose upgrades, multiply veh files;
-get headlight lenses into hglo sequence somehow;
-consider making all new body object with slightly more flared fenders for wider wheels;
-consider building tail and front objects for graphical aerodynamic upgrades representations.

Released early as 0.25 version. I have made physics and the model.

Instructions and tips:

Upgrades:

- There are two engines at the moment. Civil 180hp engine with lesser engine braking too, provides quite a lot more stable handling. The race spec 220hp engine also with harder engine braking, a lot more zippy, and also little bit more demanding.

- You may use faster steering rack, that will make sporty driving easier and steering feel more detailed, although steering is heavier.

-There are two brakes options. Weaker brakes might be a little more stable, although obviously longer braking distances.

********************************
Handling tips

- When approaching turn lift off and/or dab a little on brake pedal. Rear end will start gliding. Modulate throttle accordingly and do the steering, sometimes it is enough just to steer with throttle. Straighten wheels at the exit. Sometimes will need to do little extra correction. Try to d oneutral steer (four wheels drifting), congratulations, now you have mastered the car.

- You can use understeer to limit oversteer, also to manage more equal tires wear and heating.


*********************************

Setup tips

- You can lower tire pressures a little, but it will not neceassarily make car better, as it will make car less stable.
- More fuel load helps with stability.
- There are settings to push mass distribution a little forward, also helps with stability.
- Stronger differential coast lock could also be useful to achieve more stability.
- In general stiffer front springs and dampers will provide more stability while decelerating.
- There is a bit of room to reduce ride height.



Whats next ?

- Still lots of graphical things to improve, especially for interior, but exterior too. Texturing and modeling.
- I would love to add racing steering wheel to go with faster steering rack upgrade.
- Fuchs wheels would be nice as upgrade. Not all gauges are working.
- I will be adding more upgrades. Wider wheels option, better aerodynamics, 2.2L race spec engine.
- Collider needs adjsuting.
- LODs and optimisations.
- Making sure AI uses correct upgrades, as it might cause some confusion sometimes.
- Adding more cars to teams (drivers, colors, adding liveries).


Feedback

- Constructive feedback that might lead to improvements is very welcome. I hope you'll enjoy the mod, have fun.
