for a car like the CX-7, I'd go with the middle wheel's. You need something with beefy spokes for a car of that size to look good imo, just because imo the spoke size should compare proportionaly to the size of a car.. small cars can pull of thinner spoked wheels because the car too is relatively small and dosent overwhelm the wheels... but put the same wheels on a big SUV and it looks like crap since the sheer size of the car makes the spokes look absolutely tiny by comparison.
that last one would look great on a CX-7 in all l ikelihood. I'd stay away from momo pedals and shift knobs though, they're terribly cheap crap last I checked.
Ill throw a vote for the last one. Like others have said, it'd look great on the cx. As far as pedals and shift knob, I like the stock knob and Im not a fan of pedals. My foot always slips off the pedal of my brothers G35 when my shoes are wet.
I like the 2nd one....3rd is nice too but think second is best. I absolutely love the ones that the copper red owner had on his in one of the threads. Good choices though. Not keen on the shifter...pedals are fine.
