guess nobody could give a shit, eh.
+1 and they can be had pretty cheap, they are lighter than our boat anchors and easier to keep clean. Also it gives the guys/gals in those pokey rx-8s a well needed ego boost.Use the RX8 wheels ..it looks so factory. 18*8 50+ Offset...perfect!

Yes, especially as the weight is shifted toward the center of the wheel. Meaning, less weight in the rim reduces the work required to rotate the wheel to a greater degree than less weight in the hub. If memory serves, the moment of inertia is related to the square of the distance from the axis of rotation to the mass. This also means that of any two wheels of the same weight and distribution but different diamters, the smaller diameter one will require less energy to rotate. I used to know all this stuff in my college days, but all I remember was being absolutely amazed at how much energy it takes just to rotate the wheels and tires of a car at 60 m.p.h.Is lightening your wheel going to do anything performance wise if you don't lessen the diameter as well?

Yes, all 18" RX-8 wheels will fit. You wouldn't want the 16" Auto trans wheels anyway.Thanks for the info - keep it coming.
The RX-8 wheels people are speaking of; is it safe to assume that *all* Rx-8 models/years will fit?

Just a bit of possible caution guys...
The RX8 wheels are much lighter but this may be because they are designed for a lighter car with half the torque.
I used to run a 2000 Audi RS4 (similar weight / torque to our beasties) and that had a problem with wheels bending at the inner rim if you were accelerating hard and went over a minor pothole. The torque of the engine exacerbated the problem because the shock impact was increased as the wheel 'climbed' out of the pothole.
It may be worth keeping an eye on things if you run RX8 wheels - it is hard to detect minor inner rim bending through steering feel alone. I used a length of wood with chamfered ends as a diameter gauge to check mine.
The problem was known to be reduced if tyres with stiff side walls were used - the accepted choice was the Michelin Pilot Sport 2.

No - I don't think that would fit - but there's only one way to find out.Is anybody running 18x8.5? The wheel I really want seems to be available in a +48 but only in 8.5
