Theoretically, the best you could hope for is to make the ctr2 on par with the ZZII, but thats going to be hard work. and even then the tire wear would be a pain. one might have better luck with the rgt, but still alot of work.
Currently my roomate is working on a rgt to compete with my kaira, he can beat me in the straights, but not by much. it takes him the full length of the Tokyo r246 straight just ot get a car length ahead of me. And its pointless because i beat him on every turn. I think one would have better luck with a Skyline than any of the RUFs.
