Hi all,
After reading into the great debate of whether or not machining is necessary, I decided it's just safer to have the bore machined out professionally. I've read the bore is 57.1, but they also wanted to know how deep I want it to go to clear the hub. Half and inch seems like plenty right?Id like to take off just a bit more than what's absolutely necessary.
Thanks

How much are they charging for the machining? I could measure the hub for you, but it's raining right now.

Just measure the center lip on your hub or the center of your stock wheels. Measure the height of the center lip and add about 1/16 inch to allow for tightening the lug nuts.

They're charging $100 for the set. I ended up removing the front wheel only because I figured that was the deepest hub (and I was using a very loud electric impact on my driveway at 6am), and it was just shy of 1/2", so I told them 5/8" just to be sure

On the rear hub I get 0.695 ". There's also a bevel cut around the perimeter. I'd suggest you take one of your stock wheels to them so they have an example and you don't have to pay them to do them again due to incorrect info provided.

Edit to clarify: There's also a bevel cut around the perimeter of the opening of the wheel where it fits against the hub. I checked both 14 and 15 inch stock Fiero wheels and both styles have the bevel cut in them.

The TC wheels are a popular swap for the Fiero, so they probably have the 5 x 100 lug pattern. Several locals have had them and I don't remember tham mentioning having them redrilled. Centerbore is the only difference, I believe.
