Does the stock 8 rim fits into the 3? I know it fits for the 6.

We are probably getting a Mazda 3 rather than a 6 (don't need the size of the car, just the same engine).... if it fits the 8's wheel than I will have a new wheel for track day.

yes they will fit on a 3, just get 225/40/18 for the tires, haha i learned that the hard way cuz when i got the rims i didnt realize that they were 225/45/18's stock so now i got 4 extra tires i dont need, but thats a good choice if ur gonna chose the 3, i prefer the 3 over the 6 anyway, better mpg, and it looks better than the 6 imo, but i still like the rx-8 only wish i had alittle more money i would have bought the 8 over the 3, cept insurance would kill me thats why i chose the 3

Sweet.......

What is the stock wheel offset? I wonder if it will fit on my 8 for some drifting practice?
(you may see the offset in the inside of rim).

We are only 1 kid family and not expanding atm so I think we like the 3 more now, plus a few $K cheaper - sparing some cash for mods on my 8.

Oh found the answer:

Not to go too far off topic...

But technically you can get 6's cheaper then 3's currently. The 3's tend to have little negotation (they sell really well), while the 6's have some crazy negotiation rooms.

Some individuals have recently gotten (v6) 6s MTX's (NEW) for 16k with employee pricing (some dealerships offering it) and about 3k in rebates.

And if it matters, even after being out a year longer then the 3, the 6 still has less MRI's and TSB's. The dealers don't call it the TSB3 for nothing!

Still a sweet zippy car though. Just make sure to get an 05 or 06 to skip alot of the inital issues. If you are getting a 6s ATX, make sure to get an 05 with the 6spd ATX to avoid all the inital problems with the 5spd Jatco ATX.

you mean 8.5? Yes it would. But ideally you should go with a 245 tire.

Smile Winter weight.....

Just put the "snows" back on, and noticed that they were noticably lighter than the summers, so got the scale out.....

Summers (stock Bridgestone RE040, very worn) on stock wheel - 50.6 lbs.
Snows (new Toyo Garit HT) on cheapo-cheapo 17" FRD rim - 44.6 lbs.

Wow, 6 pounds per wheel, that's huge!

Are there adverse effects of increasing the front tire width too much? Like increased required turn in force?
