These are a direct swap several of LS Camaro owners are swapping to and claim they are direct fit... I am putting a set of LS Camaro Calipers with the c4HD 13" rotors... If the 14.5" rotors and cts-v calipers were not so expensive I would try them. LS calipers you already have a clearance issue with the shock, I could only imagine the clearance issues with the 4 piston calipers.. So my question is who is going to spend the $ and get the 14.5 rotors and do this swap?

87 GT series 1 3800sc (7.597 @88.53 1.579 60ft) (series II swap in progress) 85GT Northstar/ 4t80e 86GT 3800 n/a My Build
I was planning on converting my LT1 Trans Am to CTSV brakes in the front, its not as terribly expensive as it seems. I still plan on doing the swap later down the line (requires swapping for LS1 spindles) and I have a full set of stock size pads/ rotors to install anyway.
Amazon has the best price for the 4 piston CTSV calipers (the ones you want, better for track duty and cheaper than newer 6 piston) + pin kits for under $300 shipped. Search the caliper part numbers on amazon, one of the pics is a transmission pan but its the right part. Problem is that for f-bodies at least, the calipers must be spaced out from the spindles. People have reported uneven pad wear.
2010+ Camaros (and IIRC C6 Vettes) with brembo brakes use the same combination, no spacing of the caliper is required and they wear properly. Only thing is that the rotor needs to be honed for f-bodies (I dunno if the size is the same for Fieros) and obviously (for Fieros) redrilled. They are more expensive however, so you get what you pay for.
IMO this is overkill for a Fiero, a set of Lebaron or even 12" Vette brakes should be fine and cheaper. Remember that you're adding a solid amount of unsprung weight.

Unless you're adding 1000 lbs to the Fiero's weight, it's totally unnecessary to have brakes that large. (The CTS-V weighs about 3800 lbs.) Even on the CTS-V they're a bit overkill, as the car is packed with ABS, DBW, torque management, and traction control features.
I wouldn't go larger than 13" on a Fiero, unless I was building a pure track car for a GT series, and would only go with 13" rotors on a street car if I was putting in a much heavier drivetrain than stock. There is a limit to effectiveness of increasing rotor diameter on a street driven Fiero. You'll be likely to lock the brakes up sooner, and in an emergency situation, find yourself sliding directly into the thing you're trying to avoid.

CTSV '09+ has the best stock brakes of any car I have ever driven. Simply amazing. Furthermore, I am in complete agreement with you about brake size on a Fiero. I have never once driven a Fiero and though it needed bigger brakes. I have done it to fill up the inside of large wheels, but it was for cosmetic reasons only. It actually hurt the cars braking performance overall.

Yeah, I'm sure the CTSV stopping power is amazing, with those 14.5" rotors up front, combined with all the tech in that car to control every aspect of stopping it; despite the fact that it's a 3800 lb boat.
Wouldn't mind having those brakes on my Avalanche though. It's got another 2000 lbs on top of the CTS.
there are two reasons for having larger and larger brakes on performance versions of production cars:
1) aesthetics - it simply looks better if the brakes can fill up the space inside the huge wheel which is needed to fill the space the designers left when designing the cars with what used to be big wheels
2) a lot of people will think that because it's bigger it's automatically better and if it's smaller it's automatically worse. And the manufacturer does not want anyone to think their performance car is in any way worse than that of another manufacturer
14,5"... well... If that's what you want, go for it. Personally I'll try to make do with 12" x 0.81" as long as I can but wouldn't mind stepping to 4-pot (or even 6-pot) calipers and if those then dictate a different rotor... oh well...
