need help with Z rims and tire sizes

[Team_Undisputed]

so there is a drift event coming up soon (its gonna be my first event) and i was talking to this one guy that is holding the event and he recommended me getting new tires on my car and right now i have the stock 04 350Z wheels with the 225/50/17 in the front and 235/50/17 in the rear and he told me to get some 215/45/17s in the front and the 225/45/17s in the rear. now my question is am i going to be good with that setup or will i have my tire strecthed?? oh and its on a S13 btw. thanks guys!

Sounds like you are gonna stretch the tires a tad tighter and reduce your rolling radius a bit.
