Vette caliper modelled

A semi-accurate (hand measurements) model of the vette caliper has been added to the assembly:




before ordering the rotors, which I nearly did, I realized it might be a good idea to see what the guys over at rejsa.nu would say. After all, they have some experience with these sort of things.

Corvette brake upgrade adapter - second revision

As you can see, I did a bit of work on the design of the C4 brake upgrade adapter. The model of the rotor was modelled from measurements given to me by Art at corvette central. I guess I should be placing an order for those rotors soon now that I finally have the money.



Here we have a slight quirk. Although I consider this design better than the original design mainly because it makes use of the original threads (the original design, which can be found over at pennocks fiero forum or bubbajoe's website, required the threads in the upright to be removed and the adapter threaded to take the M12 bolts) it's not without quirks. I think I will make use of longer bolts and add nuts behind the upright to secure them. Probably not needed, but better safe than sorry.

Putting a stop to it

Behold, my current car project. "What is this?" you ask. Well, this is my take on the Corvette C4 12" brake upgrade for the Pontiac Fiero. This swap was described in detail over at the fiero-forum (fiero.nl) and was an obvious choice. But there were things I did not particularly like about that swap. The major thing was that it used M12 bolts in place of the original fiero (M12 fine) and Vette (M14) bolts, requiring the threads in the fiero spindle to be drilled out. So what you see here is my first attempt at improving the adaper.



So today I got some information from Gus at corvette central regarding the C4 brake rotor dimensions and the difference between the 84-87 and 88-96 base rotor (11,5 vs 12 inch diameter and a difference in offset). Once I had this, I included it in my assembly:





No, that is not an optical illusion. I have a design flaw, causing rotor to bracket interference. Well, that will be an easy fix. I think. I also need to add a wart on the adapter to act as a steering stop.
