Guys!
I have a widow of oportunity here (Or so i think!) i can buy front calippers and discs from a 88 vette, but since all guides and wright ups i can find only talks about 84-87 calippers, for the front, i don't dare to buy. (Even though the discs alone is worth the $$$...)
From what i can se, the 84-87 calippers are ONE piston, and the 88's are TWO piston calippers. I have a set of adapters at home (Boroved) and i can tell the mounting holes for the 84-87 are 9cm apart, for the 88's they are 13cm apart. I have not made adapters for my self yet, and i might make adapters for the newer 88 calippers instead.
I would like to know if there is any other known isues going with newer calippers..? (Iwe been searching Peenock's, and reading to my eyes bleed for two nights now, trying to get info on 88 calippers, or why not use them. I'm sure the info is out there, but i need to know yesturday... The guy selling, is waiting for my answer.)
Any one, please send me in the right direction. 
Thank's
Kristian.

The 88 calipers do need different adapters because in 88 they used a dual piston caliper. But they will work with the correct adapter plate because I used 88s on my car. The design drawings on the forum here are for the 84-87 only.

OK, thats just what i wanted to hear. Thank' Ryan.
The mounting wholes on the 88 is 13cm, 4 cm wider than the pre88. I have not made the adapters yet, so the dual piston calippers looks better for me.
When i made the adapters i will post the drawings here if you like.------------------

When I built the brackets, i first built them out of wood then I transfered it to a 1/2 piece of steel. It worked out perfect with a couple of washers as spacers. I really didn't do any drawings or measurements. I found this to be an easier way.

Thats just the way i planed on doing it. I will mount the brake parts, and then look that i can turn full in both directions with the suspension in all angels.
I will have the car on stands, and just use a garage jack to compress the spring to make sure the calipper doesent touch anything. Then i will take the wooden adapter and have it made in construction steel. (Or posibly Titanium, if i can afford it.)

I do not believe this question has been answered yet. Does anyone know the answer for us 88-ers? Are the adaptor plates the same or at least similar?
As an alternative, there are offset brackets available that allow the use of larger Corvette rotors while still using the 88 stock caliper - http://www.westcoastfiero.com/brakes/brakes.html. This does not look like much of a different setup and could also be "homemade". What kind of compromise might this be? The larger rotor would be the same, but what is the comparison between the "squeeze" of the 88 stock Fiero caliper and those of the Corvette? WCF says 20% improvement over stock Fiero for his setup - it also appears to be studcentric for the rim.
Another question: Can the hub-centric vrs stud-centric problem be remedied with wider more elaborate concentric rings? Perhaps wider ones with a step to the same OD as the raised lip on the stock Fiero hub? Are any factory arrangemets (any car) lug centric or are all original hubs hub-centric? Any I've had appart I believe are all hub-centric.

Will do, if i can find another set of 88-> calippers. The once i had in mind was sold. I was to slow deciding.
Now that i know they would fitt, it will be easyer to find me a set. 
Not to big market in swden for Corvette calippers though, so it might take a while.

Please help, I hope someone see's this soon.
I am planning and buying the parts for this Corvette
brake upgrade on my Fiero. I have the calipers and brackets.
I ordered the adapter brackets from the Cheetah site.
Waiting for them to show up but, haven't heard anything yet?
Anyway, I was about to order the ROTORS and when I
asked for 88 to 96 12 inch standard duty ROTORS
they told me the rears are 12 inch but, the fronts
are actually 12.8 inches. Is this right???
Would love to hear from those who have done this.
Thanks, Bob
