Welcome to the forum!

Can you post some pics of the hub and bracket? What size rotors are those? Are you doing the rear as well?

The hub is somewhat standard milled off rotor of of the stock hub. Corners had to be taken down a bit to clear the rotors. I should mention the rotors are Subaru and not ATS that are 5x100. Rotors are 13" ish



The bracket can be seen below is around 5/8" mild steel with M14 10.4 bolts.






The rear brakes will be upgraded after the booster/master cylinder. The plan is to disable the stock proportioning valve and replace it with an adjustable one that can be dialed in.

This goes on next

What a great thread. Brakes are ALWAYS an interesting topic on the Forum. Please share with us the details on your Fiero along with the details on your swap. Drawings of the brackets and other details will be appreciated by almost everyone.

Are you doing this upgrade for the 88's or just the earlier cars? I'm watching intently, as I'm sure many others are......

Nicely done!
Welcome to our obsession.

Bracket to convert ATS booster to Fiero is complete, its a little bigger than the stock but whos complaining. For anyone wondering, the stock fiero master cylinder does not have the volume for decent brakes, plus its nice being able to buy replacement parts off the shelf.









Also for anyone wondering, below is the dimensions of the adapter bracket for the front calipers.



Next step, adapter to connect the new booster rod to the Fiero brake pedal.
