Easy drifting cars (.car files)
Hi, I've been playing the original, but the cars do not drift much, nor easily.
So I modified an existing car's parameters (a lot), until I found it comfortable and much more playable.

This "3S.car" file is for the "Mazda 3" car (short name 3S), links:
http://cars.vdrift.net/node/7
or
http://vdrift.svn.sourceforge.net/viewvc...a/cars/3S/
Just replace the original 3S.car file with this.

The tire settings give a feeling somewhere between wet tarmac and gravel, the car can even drift a circle in place, on full throttle and steer, at 2nd gear. (It can be made even more sleepy by lowering a3 for tires e.g. to 375).

Code:

The second settings I use (also for 3S) give more engine power and torque. This one feels more like tarmac, at the same time allowing to drift only by steering or applying brakes (set on 65% to rear). You can make a copy of a car with different setting by copying folder 3S to e.g. 3SF and in 3SF saving this file to 3SF.car.

Hi CrystalH

I havent tried your settings yet. Will do asap.
Maybe a stupid question, but are you drifting with ESP/ABS on or off?

Right, good question, i forgot to wirte this. I turned off ABS and TCS, and also set to zero the speed affect on steering. (its kind of more natural this way, for me)

Yeah, I was just asking because it's virtually impossible to drift with ESP/ABS on. Big Grin
