From what I have read the D-force Spec Miata wheel was new last season. I searched the forum to see if I could find some reviews of this wheel and could not find anything. So, has anyone used this wheel and what do you think?

I bought a set last year. Two data points:
I weighed all of my wheels over the winter, and my D-Force wheels averaged 13.4 pounds each, while the rest of my wheels (all Kosei K-1s) averaged 14.2 pounds each. That's pretty compelling.
There's a wheel eating pothole at one of my local tracks. Driving into that pothole with the Koseis on pretty much guarantees that you'll bend a wheel. I drove into the pothole with the D-Forces on, and I bent a wheel. This highly unscientific test suggests that the D-Forces aren't vastly stronger than the Koseis, but obviously that isn't a definitive statement.

I bought a set for my '94 late last year and used them for three days of heavy track time at the Roebling Double school in February. They still look new as far as I can tell. I really like the silver five spokes and the double fill valves on each wheel not only look cool but are practicle as well. They are on the car here:

If you don't have extended length wheel studs they are difficult to put the lug nuts on. In addition a 19mm socket BARELY fits in the hole so if you are going to use them you would be best to switch to 17mm lug nuts.
I prefer the Team Dynamics Pro Race 1.2 over these wheels.

I purchased a set of these last year, and a set of the 5zigen wheels from Mazdaspeed (each set ran approximately 20 sessions). VERY similar look, and from what I can tell, no performance difference between the 2, and the D-force are considerably less expensive. Only 2 notable difference between the 2 wheels is the D-force wheels have the 2 air valves and do have the deep lug holes.
I just aligned/scaled my car last night in prep for the season and checked for runout. No bends in any of the wheels, both inside and outside lips. Some curbing, rumble strips and a few 2-wheel agricultural events took place last year....
I like these wheels over the TD 1.2/3 for a few reasons (my old race wheels and current rain wheels are TD 1.2): -5 spoke design makes it easier to do quick checks on brakes and other bits with the wheel still on. -Flat rim makes it easier to check toe settings -lip on rim makes it easier to attach camber gauge - I put it on, let go and adjust camber until its right.
