Another thing to think about, when going with 17's, is if you have an ATX or MTX.

If you have an ATX, I would not suggest you go with 17's unless you are just modding the car for look's. If you do, that is about all it will be good for. An ATX already has enough drive train loss to kill a horse and adding 17's just increase's that loss.

If you have an MTX, then do whatever you can afford.

Just trying to tell the truth here. Ask Hector! He can tell ya first hand. Although the car will handle better, the top speed and overall striaght line performance will fall.

There will be a dyno in HSV, right? I will bet cha!!

I went back and did that Miata Tire calculater and it shows that with your new tires on the 17's you have, that puts you at almost the exact same measurement as my stock 15's, sooo I shall eat my words...

tires or tires/wheels that effectively increase the OVERALL diameter of the tire. Of course, that 2nd choice would mean bad things: for each 1/2 inch you closed the gap, you'd also be raising your car that same 1/2 inch.

I never thought of this before, but that is exactly why my car seems to have such a bad-a$$ stance with my 15" rims:



Granted, theres an extra 10mm offset too to push the wheels out a bit, but not putting 17's on keeps the car real low to the ground, and she handles REAL well

Also, since those rims in that pic are only 15" rims and weigh less than stock rims (IIRC about 16lbs each compared to the stock 22lbs) the car feels alot quicker in the summer when I have these rims on (i use my stock rims for winter wheels)

EDIT: not to mention that even with only 15" rims and the BAT handling kit, my wheel gap is nearly perfect:
