    Converting a Fiero to Corvette 13 Brake upgrade plans

    Corvette/Fiero 13 Brake upgrade HELP

    Hopefully, some of you members can add some information to settle confusion on what will work and what will not. Ready made brake conversion kits are overly expensive to say the least.

    Considering upgrading to 13 Inch brakes on an 1988 Fiero GT utilizing corvette rotors and possibility the Vette calipers.

    From doing reading on various forums. It appears that vettes from around the late 80s on had a HD suspension option which had 13 Rotors in the front and 12 in the rear.

    I would like to utilize the 13 on both the front and rear. Has anyone done this?

    If so, does anyone have plans for the brackets and concentric rings? Or, where one may look to find them?

    How about the e-brake setup?

    Can anyone shed some light on this?

    Thanks all. I sent an email to fieroaddiction. Anyone have any idea why his web site has been down for a while?

    For the 1988 Fiero forget about having an e-brake. http://www.design1systems.com/ has a C5 Z06 13" rotor/caliper kit for all year Fiero. It's not cheap. They don't advertise it on their site, you will need to call. No e-brake either. I think you have to replace the booster.

    For the '88 Fiero your best solution (most economical) is to do the 2nd Gen Corvette C4 12" rotors. You keep the stock booster and '88 Fiero calipers (yes the e-brake too). It betters the braking at least a 30% from what I have heard.

    Parts you need are the
    -3/8" thick adapters.
    -concentric rings.
    -2nd Gen C4 12" rotors.

    EDIT:
    From what I heard the C4 brake kit from WCF touches the front suspension parts on a full turn.

    It appears there have been many options on using the 12" rotors as well as the most popular due to cost. I would prefer to use the 13s due to the rotors showing through the 19" wheels on my build. I think the 12" will look small in comparison. Since the real deal uses 14" I prefer to go no less than the 13s. I was hoping someone would have plans for the brackets and concentric rings so I could save some money putting the kit together myself. I know of someone who offered to machine the needed brackets for me at a minimal cost.

    I felt the same way about the 12" rotor size for my 18"/20" wheels on my '88. Good luck in your search.

    Sean;

    I was just procrastinating over on Pennock's for a few minutes and saw that MadCurl over there has just commissioned a shop out in California for 13/14" brake upgrades for his Fiero project. He said that the shop now has cnc template/plans to make for the adaptors.

    I copied the thread below. The upgrade is mentioned near the bottom of page 54. The shop name is D1S and the upgrade package is for Baer brakes.

    Good luck
