I just mounted my stock tires to my new wheels. I posted a few before and after pics. The offset on the motegi's are 42+ on a 7inch wheel, thus the wheel will be pushed out about 16mm (see the stock/new offset photos). For those of you thinking about new wheels, the front wheels will fill out the wheel wells more because there is more room to the rear of the car (wider tires at the rear are possible). The slender spokes and the gunmetal finish make the wheels look small even though they are 17inch, which in turn make my Mazda look chubby.(doh) Luckily I bought a dark color (strato blue), and the wheels will hide brake dust better.
The finish on the Motegi wheels are not that great (rear lip was not painted completely and the center caps suck) but for a set of forged wheels that weigh about 14-15 lbs each, its a steal at $900 for the full set. The stock 17 inch wheels are fairly light themselves at about 23 lbs each (I'll try to get a proper measurement later). The Tires, however, weigh nearly 25 lbs each. The TPMS sensors do fit Motegi wheels. Installation was fairly painless as long as you are careful.
I'm still trying to figure out how to remove the stupid decals on the wheels but I nicked on of the spokes in the process, so I gave up (any suggestions?). Yes, I will lower the vehicle!!! I'm just waiting for Tein to produce some coilovers for the Mazda3....
