ok, so i pretty much decided on the 5Z N1 pro's in silver... 15x7 = $175/each 16x7 = $185/each but, tires.... the azenis (and don't offer anything else. I've never been more happy with a street tire and have no desire to try anything else at the moment) are a big price jump- 205/50VR15 $62 /each 215/45ZR16 $96 /each Advatages of the 16s are obvious- higher speed rating, wider contact patch. Weight, and all that, really doesn't mean dick to me anymore. I'm going to have a buttload of power. 5lbs extra in the wheels won't slow me down at all.... in fact, it might help me to get some traction. Now, mind you, this is for STREET and DD use. I'm not after drag radials or slicks. this is for everyday driving.
