Yes. There are these seven car type values which can be found easily. Displacement, power, weight, gears, cylinders, redline and drivetrain (rwd, fwd, awd). But editing those affects cars in a single group rather than each car independently. Like if you find the values that edit FXO's displacement for example, you'll find it changes displacement of all cars in TBO class. Not 100% sure but I think the change affected LFR cars too. Finding values like how to change only RAC into awd or how to change BF1 engine into inline for example, would be almost impossible without any clever approach like what Kegetys has done.
