Christmas surprise!
Use 900 degrees steering for maximum lock, if you use less steering, lower the lock to keep steering ratio same to have somewhat realistic experience, real car actually has same 2.5 turns lock to lock as G25 has, so with this I get full lock to use.

It probably has many bugs still, works only in dev mode, you put it in volvo300\RHD and indeed you need dev mode release version as this just adds one car to that.
Engine is bit buggy, it refuses to die properly, also car really should have stroked 1.4l turbo motor, but I had no time to build one yet, so it has similar power level 2.8l 16 valve EVO motor.
Differential might be bit tall too, some other issues as well.
Dampers are set quite soft, feel free to adjust, use small changes.
Championship winner used 2nd gear to get going, never 1st gear, power is 4000-7000rpm, but it does have lot of power over 8000rpm too.
This car is made to handle jumps well, lot of suspension travel, quite soft suspension, also it is really meant to be driven sideways on gravel, but it does handle tarmac too.
I made FFB bit stronger as car really has same steering components just bit modified, so it should have heavier steering, but maybe I overdid it as I can't use more than 0.4ffb multiplier to prevent clipping, but see how it is for you.
Car is based to this, some day should be fairly close and realistic one too, but for now it is very early WIP, just needed something for rally cross mod and thought that some of you might like from version with bit more driftable physics.

Some day I want to make this car, it has EVO motor, also this one has 4wd system, but when I happen to get time for such
