Those Fiero spinldes look really nice, I will try to have a proper CAD and FEA on those as soon as possible, to compare with Miata/Mustang. In the meantime, and despite my disliking for bearing units, I came through the Pontiac Solstice uprights, and they look really neat and lightweight. Anyone here that has experiences with them?
Enough info to make your spindle calculations from:
viewtopic.php?t=1572Also in the "spindle and upright measurements" thread:
viewtopic.php?f=5&t=1292#p15597There is a lot more info on the hub and brake interchange on the Fiero spindle in that second thread. And even more info scattered all over this site on bearings, hubs and brakes for them.
I've toyed with the Solstice parts. And the late MX5/RX8 front uprights. They both have their good points, but are not appropriate for a Seven. Both are too large and, for the most part, require too large of brakes and wheels to work with a lightweight car. If you are desperate for a good, small, unit bearing upright, use the front upright from the 1999+ 4x4 Chevy S10. It will still fit inside a 15" wheel and it has wide spaced caliper bosses that can be adapted to almost any caliper you can think of, including, I believe, the Wilwood H1 performance caliper. It uses the same bearing as the rear of a Corvette C4. The stock bearing has a speed sensor in it while the 'Vette bearing has no sensor.
