They have the same threads, just a different shoulder. They are not cheap though! The PO of my car had Scion TC wheels put on before I bought it. They look sweet, just ride a little rougher. A definite plus in the looks department.
The hub centers on the Scion rims are a different diameter than the Fiero hubs. I don't know if they are larger or smaller. If smaller, you will need the centers machined out. If larger, you will need concentric rings. I believe the wheel centers are smaller.

Scion tC wheels are conical seat.
For that matter, most modern automobiles have conical or spherical (Honda mostly) seat lug nuts. This eliminates the need for left-hand threads on the left wheels.

HUH ? As far as I know, the type of lugs has nothing to do with L & R threads. There are conical, straight w/ washer, flat w/ ridge , and none of them are left hand thread. Only cars I ever saw with left hand lugs were 50s Chryslers. Even my 66 Chrysler has all R hand lugs. Back then, they thought it was a safety plus....lugs wouldnt work loose on the left hand side. They apparently thought that was a problem and finally decided it wasnt.
Anyways, use Scion lugs for those wheels with the Sion wheels. Most cars now have some kind of alloy wheel and some take very specific lugnuts. Scion may have differnt lugs themselves say for steel or alloy wheels.

You need to machine out the centers of the Scion rims a little (to 57.1, I think). Someone was selling them on Ebay already machined.

Aluminum Scion wheels use shank style lugs like all other aluminum Toyota wheels. Unless they're steel wheels, then they'll be conical seat lugs; but I doubt the poster is going through all this trouble for steel wheels.

Scion TC wheels need to be machined 1mm to fit the Fiero hub. Use Toyota alloy lugs - about 6 bucks each through Toyota - you can get aftermarkets of EBay but you get what you pay for. I had a set machined for 25.00 per wheel so add at least 100.00 to the cost of the wheels. I bought a set of Wheels and tires with 4500 miles on them for 200.00 so 300.00 with good rubber was well worth it. Carver1 is 100% correct. The low profile sidewall rides stiff but it is "positive". They do sit in board a little but they still look great and work well.
Here's "The Short Bus" aka "Ol Yeller" with the Scion TC wheels and tires:
