the inner lip of the rim will ride 9mm tighter on the inside. At max turn, you need to see if it will rub on anything. Also, the outter surface when going straight will be 29mm further out than the stock wheels .... see if that's ok too.

There are no hard fast rules for combining lowering and upsizing rims. There are just too many variables. In general, I think those rims will fit fine, but at full turn, they might rub a little, though to say for sure (I don't think so). If that is the case, you lose a couple of degrees from your tightest turn that you can make .... not a big deal for most people.

 

so basically might as well just do the 1.5 in drop, keep the 205/40/zr17 and just becareful or go 215/50/zr17 and maybe lose a little turning radius, not to bad i guess, glad i didn't go 18's like i was thinking about, then my choices would be very little to none. thanks guys

 

You'll have to even more careful pulling into parking spots. For some reason I always scraped the tow hook and not the lip... odd. Anyways, it was half worn down when I totaled it.

Also, you should upload some pics to your galley. I don't think I've ever seen a 5th gen in such an awesome blue.

 

ok i made a gallery, my digital camera is on the fritz, but i had these already on my pc, keep in mind the car is dirty and i've done some more things to it since then, but i got some pics up, will put better ones once i either get a new camera or fix mine !

 

For the tire size change, use the miata tool. It will tell you how the overall height compares between the 2 tires and also with the stock setup. It also tells you how much off your speedo is. A 50 sidewall will give a descent amount of cushion over the 40's.

 

my 95 has a 1 1/2" drop. Do a search on yahoo on "tire size calculator". Discount tire has one.
Here are pics of my car. It's not bad fora 13 year old car:

hey you are rolling on the same rims as me louofm, and the 1.5 drop is about where i wanna go, so what size rubber are you running?

 

For 17x7 wheels you'll want to go 205/40/R17 or 215/40R17, the first is a little smaller than stock and the second is a little larger than stock, plus they are pretty common sizes. I had the Pro-Kits too and they advertise 1.2 inch drops, but they settle to about 1.4-5.

miata.net has a nice tire calc too.
