I think it's to do with the Drivetrain as well. I find that with my MR2, it is possible to keep up with rear wheel drive cars, but like you said, completely outclassed by the 500PP 4WDs.
True true, but only on the straights. If you would compare tham on turns,or in the corners i think that they are even or the FRs and MRs have a slight advantage, due to the less weight.
You have to take the weight of a 4WDs car into account. And the Nissan Skylines which i am driving one myself are realy heavy. And if you push the car the tyres are gone like nothing.
And if there would be a pure downhil Touge Track i think 4WDs would have a much harder time than they have now.
Now on most of the tracks we are driving on are long straights where the 500PP 4WDs can show they muscle, and they are more uphil sections as well.
But if you take a track like Eiger Short Track - or whats its called - the one section with the hairpins one after another is definetly made for light cars. A heavy 4WD has no chance of keeping up with an FRs where the driver is decent. Or the 4WD driver has to be really good - heh which i am not!!!!
I drive a 4WDs just because i am a noob at driving FRs - if I could or at least be half decent as I am with 4WDs i would switch to a FR.
But I think this should not be about whinning that my car is not that fast and i cannot keep up with that car because of a 20PP difference. It should be about that you have a car you like and you are happy to compete with.
If you would be really good you should be able to pul away in the hairpins of each track - or there should be made a new Rule to compensate for the so called handicap of these cars.
Meaning that not the whole track should be taken into account but only a part where the most corners are - so that the power does not play such a big role. That way each one could keep their cars and nod complain about a huge PP difference.
But thats only what I think.
Peace
