I searched around for quite a while looking at aftermarket wheels.
Momo definitely makes some good stuff. At a pretty steep price though. Not wanting Porsche quality.. but wanting a good sturdy wheel of tasteful design covered in something other than fake leather (ie: fine genuine Italian full grained RUBBER), I had quite a hard time finding anything for under $200 that wasn't just a really basic wheel and rather bland for what you pay. Momo has the MonteCarlo selling at around $165. It felt pretty hard in my hands though. I checked it and others out in a few racer supply stores. That's one of their bottom of the line wheels. I'm not too impressed with it's feel, not for that much anyways. To get some of their better stuff, you gotta spend a LOT of money.. twice that even. It's like a set of fine Italian dress shoes. I'll use neither in my mustang. :P
Sparco makes great wheels.. but I ran into the same problem.
Race makes a wheel through Momo, that's supposedly Italian quality.. called the Race Dragster. I've seen it selling anywhere from $138 to $69. It is however covered in polyurethane with a couple of small leather inserts to save on cost. I really like the feel of leather wheels.
Grant makes some decent wheels, but IMO- totally is inflating their prices in an attempt to compete in the Momo/Sparco market. The problem is, they're selling vinyl covered wheels well into the $200 range. It's pretty sad. Some of their wheels look nice .. but are just way too much money for what you're getting in terms of quality and life. The models I looked at in Pep Boys and Kragens have the whole leather grained rubber thing going on. Worse- there's casting flash from the mold on the wheel. Not only is it a chunk of solid rubber or thick rubber around a metal frame, the mold isn't very precise and easily exposes the fact that it's not real.. at all. The "stitches" on them are very poor attempts to look like a leather stitched wheel. I can't believe someone would pay more than a hundred bucks for that. Yet, there it was .. $129. I'll pass.
Then there's a company called Isotta. From all the reviews I've read, they make very high quality wheels without the usual Italian price tag. However, that's not always the case depending on where you buy them. Unlike Momo... some places directly import them and get them for a -really- good price. So you can spend $280 at one store.. and $133 at another. The other may take a bit longer to get, but it's worth it to me to save $150. Every review I've read thus far show people who are extremely happy with them, have had no problems with wear and tear, and some have stated that when the car is sold later on, they're keeping the wheel. That says a lot.
Here's the model I got:
Black was the color I picked.
Mania Racing seems to be Isottas preferred vendor ... and they want over $200 for it. Hub mounting adapter not included. These wheels take a standard sparco/momo hub. Pro: Easy to get. Con: Relatively expensive. The trick is to find a generic momo/sparco hub for the mustang. Haven't yet managed that... but I know they're out there.
The right deal on the wheel though.. can be had at www.nopi.com
.. one of the bigger suppliers popular among the riceboy crowd. Apparently they run 10 page ads in some of the "Sport Tuning" magazines. Hey, whatever.. more power to em. They got me an awesome price on that wheel at just $133 bucks. There isn't a single wheel out there that's covered in leather for that price. Let alone one with that quality.
My second choice was:
.. but I figure that'd be best for a street car, four spokes can be cumbersome on the track. My stock wheel was 4 spoke .. I definitely like the 3 on my S4.
I went with 350 mm diameter. 320 is available but I figure it's a bit small. Stock my airbag wheel was a whopping 380 mm. Yow. Where's my air horns?
