For those who have tried that in the front for some they've been getting problems with the TCS system, and you'll definately get some sort of rubbing when you have to full lock for day to day driving. If you're using it as dedicated track tires, then go right ahead, you shouldn't get any rubbing issues until you try to park it (I sometime rub with my dropped suspension on oem size 215/40/17 and i already have minor rub marks on my fenders, can't imagine how bad 45 is gonna be).
If anything, since you have the tires anyways, why don't you slap it on and try it out :biggrin: good luck!
