The ITS Mustang is extremely weight challenged. I'm going to do my best to knock weight off if it wherever I can, thus some lightweight wheels are needed. And yes, I read the GRM/Sportscar article where light weight wheels weren't any better on the track or dyno than wheels that weighed 5 lbs more. But I'm still gonna do it.

So what's hot in lightweight wheel world? I checked over at Enkei:

But 15" wheels on a 4.5" x 5 pattern (that's 114.3mm to you ricer boy) are not that common there. And any wheel for a Mustang that has the word "race" anywhere near the description inevitably is for drag racing.
