OK, I mostly completed this brake swap several months ago and have been very happy with the results. I still had not connected the e-brake cable until a few days ago.
Can someone post better pics of the e-brake cable setup? The problem with the pic in this thread is, the cable sheath does not appear to be fastened to anything. In that case when you engage the e-brake, the cable will just lift up from the lower A-arm instead of pulling down on the e-brake lever on the caliper. Am I making sense?
Can someone with a working e-brake setup snap some pics for me so I can have an idea what to do?
Thanks![This message has been edited by 87GTBro (edited 11-01-2006).]

After machining off the friction surface of an old front rotor and installing the 'Vette rotor over top, does enough of the hub protrude through the rotor to center the rim properly, or does this conversion rely upon the assumption that lug nut-to-rim fit will center the rim as the nuts are tightened? |

The lug bolts still retain the original location and pattern. The rim will center just as it did on the original hub. You will be installing longer lug bolts on the front to account for the thickness of the added rotor.
The concentric rings are designed to center the rotor, not the rim.
Oh, BTW, If anyone would like AutoCAD drawings of the adapters needed for this upgrade, drop me a line at dcampbell@rgv.rr.com
All you have to do is take the drawings to any machine shop with the right tools and they can run the parts for you. These are the same drawings I used on my swap and the adapters worked perfectly.[This message has been edited by 87GTBro (edited 11-01-2006).]

Thanks, but that's not what I was asking. 
On an original hub, the rim is not centered by the lug bolts; it is centered by the fit of the rim's center bore over the area of the hub which protrudes past the rotor hat.
What I would like to know is how much of that protruding area is left, if any, after modifying the fronts. i.e. are the front wheels still hub-centric after all is said & done, or does the work also change them to lug-centric?

The rims do not even touch the 1/8" protrusion or hat (dust cover) that covers the castle nut on the front hubs. If you have ever noticed the tapered edge on a lug nut, that taper is designed to center each hole in the rim over the lug bolt. This is what centers the rim on the hub. If the rim was indeed centered by that lip on the hub, it would be necessary that all rims be manufactured with identical center bore diameters. This just isn't the case.
The answwer to your original question though is:
No, this swap has no affect on the centering of the rims on any of the four wheels. Because the lug bolts are all still in the stock location, the rims still stay centered on the hubs.[This message has been edited by 87GTBro (edited 11-02-2006).]

just a little bump and a question, how much different are 97+ ls1 camaro brakes than these? The fbodys should be the same as the same year corvette correct? Thanks, Drew ------------------

Is there anyone still making the rings for 84-87 fiero's? it doesn't appear that cheetah is making them anymore. The brackets I could probably manage myself on a band saw, but the rings could cause me some problems.

I can make rings if you are interested, I actually have 2 I just made for my 97+ fbody 12" swap, but I made mine a little wider. Its .330 thick instead of .27 or whatever. Let me know, Drew
