The picture is definitely not a Fiero 88 front bearing. But then, a lot of these places just have "representative" pictures.
My thoughts, too. Probably a "stock photo".
I'm betting that what they're selling is the same inferior "e-bearing" replacements that have been around for a while.
Wouldn't mind seeing one of the actual pieces.
But, on the other hand, $300?! HOLY CRAP!
The only other bearings that I know of are the ones that Rodney had manufactured. Think they use rollers instead of ball bearings. There were some issues when used on race cars (the grease would expand, and force its way out) but I'll bet they would be fine for a street car.
