I've seen the ad a few times and the guy mentions he did a hub conversion with a brembo brake upgrade, all probably from the volvo. He's running a different bolt pattern, unless you get a whole parts car what he did is creative but expensive.
With the high offset running adapters of 19mm (which is said to be the thinnest one should use) Effectively makes them a +27mm offset. Which is probably why they appear to sit just slightly proud in the pics on the fiero.

They have a limited selection with a 5x100 bolt pattern and compatible offsets. I just wish the had a more choices for a staggered width/offset set that would work on Fieros. I've been thinking about a set along this style for some time.
