ok i like both cars but you are all right its comparing 2 totally different things. for one the sti is turbo and 2.0 with all wheel drive while the R is 1.8 N/A front wheel drive. that right there is enough because a turbo in any car will totally change the car. ( the neon for example) the all wheel vs. front drive is totally unfair too because they also have a differential control to change the power ratio so they could probably be great drift cars with a good driver whilethe R is front and for the most part alot of people can hadel it to a decent level, not to extremes tho.
i just think you shouldnt be looking at these 2 car trying to compare them because the R is truely a factory race car but is has some nice "Lurury" features too it. the STI is a bigger car i think they come in at close to 3000 lbs thats almost 500 lb difference between the 2.
you should be comparing the STI and the EVO for 2 good cars to compare because of the fact that they weigh about the same and have very close horsepower. my opinion tho would be to have both
