These brackets will allow you to put 12" corvette rotors on 88 fieros using the stock Fiero calipers. They are CNC milled, with a 1/2" thick boss where the tapped hole is, this means there is no need for a welded nut for strength. They are one piece.
You will get 2 front and 2 rear caliper mounting brackets(powder coated black or Red) and four centering rings. You will need four 88-94 front corvette rotors, they will need to be redrilled with the Fiero 5x100 bolt pattern. Also you will need eight M12x1.75 bolts about 1.5" long.
Price is $110 shipped anywhere in the US, PM or e-mail me for payment info.
I'm wondering about the centering rings.......In the one pic of the rear it appears that the centering ring sticks out beyond the rotor/wheel mounting surface. Thus requiring enlargement of the center hole diameter of the rear wheels. Is this true or is the pic not representative of the centering rings that you provide?

My question is , with the stock caliper your not really increasing your braking surface are you? with the vented rotor i assume you improve cooling greatly but, can this be clarified for me?

That is the centering ring from my aftermarket wheels, Sometimes it sticks on the hub when I pull the wheel off. I didn't notice it was on there when I took the picture, the ring that centers the rotor is under it.

Jazzman & Coinage are correct, Increasing the rotor size increases the mechanical advantage.
I only have a few sets left from this "run"

When will you be doing another run? I want bigger brakes on my 88 after I get some larger rims which wont be until later this year.

I have a question on these adapters: someone else on the forum had put adapters on his 88 and mentioned that the parking brake cable was now a bit of a stretch, is this a problem as I had not heard anyone else mention it? Also are the brake hoses long enough to not pose a problem?
Racer_JT- The brackets for 84-87's that I make are used to do this swap, http://www.fortunecity.com/skyscraper/switch/67/id215.htm It uses the 12" corvette front and rear rotors and the front and rear corvette calipers. So no there is no way grand am caipers will fit.
The brackets I'm selling in this thread are for 88's only, using stock calipers and 12" corvette rotors.
How hard would it be for you to make brackets for the HD 13" vette rotors? Is it just the matter of making the bracket longer? I'd like the 13"s on the front and the 12"s on the rear, as I’ve heard that the Fiero could use more of a front braking bias.

I don't know enough about the 13" rotors to answer this question, do you know the thickness of the rotor. If they are thicker than the 12" rotors they will not fit the fiero caliper, plus the offset of the braking surface may be differant.
Hey Sluppy here is the scenario .....do you make brackets for a 88 fiero set up to use with 88 corvette rear calipers and can you make this if so I would like 2 sets .

Has anybody mounted these on a car with the stock 88 front rims? The offset is different and I am pretty sure there might be a clearance issue as well as the back.
Nice work sluppy. I will be in contact.

I received my bracket kit from Sluppy123 today. It was exactly as advertised, carefully packed, and the purchase transaction was trouble free. What more could you ask?

Hey MTA, I tried for a laugh installing the rear rotors on the spindle with the kit. The steel bracket would have to be either shaped or thinned out by a large margin for this to work. What would the advantage be?
