im about to pick these rims up tommorow for my seven. i have a brembo brake kit on the car but its still 4 lug no conversion. the rims are 17x7 with a 40mm offset and they are 4x100 or 4x114.3. what does everyone think?

 

here are the wheels....

 

I think they will set off your car's color real nice.

 

thanks i think they will be perfect if they fit right....

 

Its gonna be all in the tire.
40mm offset on basically any 7" wide rim sounds good, but slap on a tall tire and your done.

Its gonna need like 205/40s to fit right if im thinking correctly.

 

205/40. ok. i am going to order tires on line so i need to know the exact size. how sure are you??

 

Id wait, hopefully someone with 17's chimes in.

Im bad with profiles/widths...that was just an aproximate guess.

 

Tell us about your Brembo brake kit. Is it an adaptation of an FC or FD kit? Specs? Pics?

 

205/40 front and 215/40 rear is good to drive on. I have 17"x7"s +40 all round, rolled guards.

 

my fenders arent rolled. i was thinking that maybe i would have to get that fiber glass lip under my fenders cut. but i was also told that if i dont put weight in the rear ill be fine. my suspension is stiff so im thinking that should help...

 

I think the 17's may make the car look like its "floating" since it will make the car sit higher. Thats just my opinion though, I could be wrong.

 

well i picked them up today. if they dont look right i can always resell them. i think they will look sick though. i just have to find out what size tire to put on them. anyone have any suggestions on tire size????

 

wont fit our bolt patten i've tried already

 

If you get tyres of the proper size, including outer diameter, the car won't sit higher at all.

 

GSL-SE pattern is 4x114.3

 

40 offset is perfect with SE suspension, 38 is stock.

I run 205/40s on my 16" rims, and my speedo is still accurate, with that combo your overall diameter will be about an inch larger and your speedometer will be off, be aware. I have to use 1/4 spacers up front to stop rubbing.

I have coilovers and 400lb springs

 

YEAH IM A BIT WORRIED ABOUT THE FRONT. I GUESS ILL HAVE TO DO THE SAME.

 

The rubbing is due to the squared shoulders on lo-pro tires, works out though

 

where did u get your spacers? how much were they? what size? where can i get them? also, are they going to affect driving at all, high or low speeds???? sorry for all the questions...

 

I purchased them locally at hubcap express for about $8 @, they are 1/4" thick and I had to get longer wheel lugs (GSL-SE) which I picked up at a auto store who had a guide and the correct ones in stock, nice when it works out so easy. I had a sample of the stock lug.

 

oh ok cool. ill do that if i have to. thanks for the info.

 

For appropriate tire size use this:

http://www.miata.net/garage/tirecalc.html

With a 205/40-17:

Diameter: 23.5 (stock 23.7)
Revs/mile 860.0 (stock 852)

Speedometer will be 1% fast.

Oh, and FWIW, with 205/40-16's as mentioned by aussiesmg the diameter is actually 22.5, so aussiesmg is going to have a bit more clearance than you will in the front... (you could get about the same clearance with 205/35R17's though, if necessary)
