Dodge Challenger


The Chally is my most familiar car due to the fact that I was creating it from the scratch.
The real car is RWD however due to not very precise tire physics in ROR the virtual car was completely undrivable when RWD only. Even though, the car is very oversteery now with 4WD and quite challenging in corners.

The suspension is very soft which is very useful in ROR envionment. It makes the car very predictable in corners and causes weight travel during braking and turning. The jumps are not big deal for the Challenger. Just remember to strighten the front wheels at landing point.
You should release the throttle at entries to the corners. It will make the front of the car heavier and gives the front tires more grip. Push the throttle even before the apex. This will make the car oversteery, however the car likes to do the corners with a little drift. Just turn in a little and push the throttle - the car will swing even more by itself. You dont have to brake much before corners because you will loose some speed when making the turn sideways.
The front wheels dont turn as fast as they should so make little change in challenger.truck file. Change -0.1 and 0.1 Hydro values into -0.12 and 0.12. This will make the car more controllable.

Lets talk about dark sides of this baby. The car is not tiny so the barriers will seem just a bit closer than in other cars. The hairpin (turn 11) is not very friendly for this big muscle car. It can be taken with a 4 wheel drift, however it is very hard to achieve because of the barriers. It will save you at least a second if you menage to pull this trick.
The suspension is easily breakable so dont hit anything, especially with naked front wheels. It is common that the wheel disappears inside of the body. You can pull it out easily wth the mouse cursor but you can say bye bye to your good lap time. Sometimes the wheel starts to wobble at higher speeds. This means you have broken the spring and the wheel has no suspension. If you encounter the problem very often try changing the shocks section in .truck file. Change the sixth value ( 0.1 i believe ) to 0.66 or simmliar in every shock, this will prevent the springs from breaking.

Final truck file here.


Laptime

I managed to make 1'34.49 with a little mistake in 3rd section. Perfect laptime that could be achieved from my laps is 1.33.15. I believe 1.31 is possible.

Perfect lap:
Section Section time Summary time
1 13.535 13.535
2 22.353 35.888
3 18.400 54.288
4 11.152 1.05.44
5 27.711 1.33.151
