I have a complete set-up like this (the WCF set that fits all years) that might be coming up for sale or trade after I sell my 88 Formula and get an 87GT. I could possibly do some trading for the 11 and 1/4 conversions because I'll need (2) of them (1 for my 85 as well whatever else i get) .
I was thinking of using the 97-04 corvette calipers and making my own brackets. Why not go with the newest stuff out there??? They are all over ebay!! Just need to get the abutment brackets with them.
Posted by Fierofreak00 on 12-31-2007 I'm still waiting for someone just to make them. - Jason
Jason probably thinks we've let him down. We're preparing to machine up brackets and centering rings and make them available. Jason has agreed to help us test fit the designs till we get them right.
We'll make them available in "sets", and you'll be able to get Fronts and Rears separate.
We've had a bit of a delay since we've had a mill down, and have been swamped at the start of the year. I think now we're just a couple of weeks away from doing the first prototype pieces.

I am trying to install the rear rotors but it is touching as you can see at the photo.
Is this the right rotor? From what I see in the photos the rotor should have a cone and not a cylinder shape like mine. Does anyone has a port number please?
I know that the 88s are not exactly the same as the '84-87s. Could some one tell me that the differences are between the '88 and the '84-'87 Fieros with regards to the brakes? I have a nice set of forged 16" wheel, (that I want to keep) on the car. I would really like to put a set of 12" C5 rotors & calipers up front and a set of 12" C4 calipers and rotors on the back. I don't know if this is possible or if it has been done before. Any information or assistance on putting 12" vette brakes on an '88 would be greatly appreciated. Thanks.

Bump to see if anyone has heard from cheetah.. I would like to purchase his adaptors..
Also, I would like to ask, since i have collected all my parts except the rotors.. I will be purchasing rotors front and back for the 88-96 vette to go on the fiero front and back respectively?
When you guys say drill out the holes on the spindle, you mean the 2 holes on each spindle that mount the bracket right??
Was there somone in Titusville FL that was working on adaptors?
Found the info. Read below.

I haven't heard from Marc (Gwain) since this last post. I belive he may have lost interest in this. Oh well, the search continues. -Jason

Could someone make adaptors for 13" Corvette brakes?
Are they much more expensive than 12" brakes?
I bought the 13" HD vette brakes as a whole set and another front-only set that are the regular 12" style. The rears are the same on both as far as I could determine. When I did a test fit of the 13" HD brakes inside my 17" wheels, I had less than 1/8" clearance between the caliper and some glued on wheel weights on the inside of the wheel. So if you want 13" fronts, they should fit in a 17" wheel. But it's VERY tight. I'm going with the 12" rotors on all four corners. I'll get some measurements and for a "+" I'll draw the brackets for you. Just be patient. It might take a while until I'm done with mine.
And "No" they aren't that expensive either. The calipers are the same. The abutment brackets are wider to allow for the wider rotor. Of course the rotor is also taller @ 12.8" or something like that.
1/2/2009 Correction: The HD calipers ARE NOT the same! They are about 1/4" wider to accomodate a thicker rotor.

When it's all said and done, I'm shooting for an 18" rim, so there should be plenty of clearance.
Thanks for drawing up the brackets. I really appreciate it.
Can't wait to see what it looks like when it's done.
Here is the drawing of my adapters to put 12" C4 rotors AND CALIPERS onto the front of an 88 Fiero. I had to remove a section of the C4 abuttment bracket. But otherwise, they're easy peasy. I don't have the rears drawn yet. Adapter_Brackets.xls
***Edit *** Done with the backs now. Enjoy!
1/2/2009 Update - Major design flaw with the 12" C4 mod that I put on our car. See my seperate thread before using my info to put C4 brakes on your 88.

bumping this back up, hoping some of you have gotten this conversion on the road and had some experiences with it.
any ideas on how to get around the hub centric vs lug centric issue? One of my wheels is lug centric (I could only get 3 wheels with ET38 and one with ET48, which requires the use of a 10mm spacer. will probably try to get a matching wheel with ET48 later on if I keep the car) and it does seem to be centered, but I haven't driven it past 30mph yet, so I don't know it it would be an issue for me...

Just starting this upgrade. I may have brackets custom made if anyone is still looking for them. I have a friend that works at a machine shop and was saying once they get the machine programed not a big deal to make more. He will let me know costs in the next couple of days.
I have a question about this swap. My friend said that if I am going to be doing suspension work I might as well swap to the 88 cradle and suspension. That was an overal better suspension geometry so I agreed. He said I should also swap to 12" Vette rotors like these.
Another friend says that I cannot use the C4 calipers if I swap the rear end to 88. If this is true, does anyone have any idea what I should do?
You should get them to match the same style as the calipers you are using. If you are using the calipers with the ebrake, then the brackets should be from 88-96 as well.
hey if anyone wants to do this swap, I just got a great deal on calipers and brackets, even pads from the corvette forum. check the classified section out, there are quite a few guys parting out corvettes.
sorry, i meant in the corvette forum's classified section. A guy named Ralph emailed me saying he as tons of corvette break parts and is located in Shelbyville IN. His email is indianavette@aol.com
So i was curious if the lines on the master cylinder had to be swapped? ON the corvette master cylinder the smallest hole is on the front of the master cylinder and the larger bore line is on the back of the master cylinder, whereas the fiero is opposite, the larger line is on the front of the distrubition block and the smaller line is on the back. I would assume the larger line is for the front brakes and the smaller line is for the back.
