The question should be why? Why would someone spend that much money to rice a type R? Tell your friend to spend his money more wisely, get some lightweight 15s with some sticky Azenis or other good rubber.
An R is about purism, it's about appreciating a perfect front drive car, and most importantly about going fast, leave the 19s for the riceboys.
I'm not trying to be a hater, but it's just such a waste! Also tell your buddy to study up on rotational inertia, sprung and unsprung weight.
