Yes, the fit is VERY CLOSE and still requires a 1/8" spacer. Longer competition length studs are a very good idea as well.
I have them on my 68 Shelby. The vein is machined off. (80% +/-, like picture) It is NOT a fluid vein. I have to presume IF it was intended for fluid, it was never used.
I have done two sets of these and neither set had fluid passages in that part of the casting.
I always presumed that it is there as a casting reinforcement?
A simple 18 grit disc in a grinder cuts it right off. It is not high nodular iron. It's soft like GM blocks are. Not like Ford nodular iron is.
ANY way you look at it, it is still cheaper than $2000 a caliper.
The Tbird caliper weight is 6 pounds. I don't have a rotor here to weigh for you but as I recall, the difference between the .830" stock rotor and the 1.25" rotor was much more significant then the calipers? You are doubling the mass of the rotor. That you cannot avoid.
You can't run aluminum rotors, just iron rotors with aluminum hats. That really isn't going to save you much. Maybe a pound total?
SOME of those aftermarket aluminum hats have a very bad reputation for exploding under racing conditions. I'll take my chances with the heavier iron one piece rotors.
How much does that Group 3 Girling set up weigh?
This is still a better deal. Parts are still available for this set up.
I can't post a picture of the Shelby with these on right now. I don't know where that folder is at the moment.
Maybe later this week if someone needs to see that?
Just trying to help here. Very few perfect solutions are available.
If you want a direct bolt on (which for $10,000, those aluminum set ups still need modifications) then you are going to pay someone for that.
Like the commercial says, "pay me now or pay me later" I suppose?
Here is a Tbird caliper with most of that vein cut off. Takes about 5 minutes to do. I have seen them with it completely removed.
It does not seem to cause any kind of issue.
This one is about 80% removed.
With a 225/50-15 tire, on an 8" DT rim, you have quite a bit of room to use spacers before you have fender interference. Sitting on pavement, I can put my hand between the tire and the fender lip.
A 245? Well that's a completely different story right Jack? That's the proverbial 10 pounds of mud in a 5 pound sugar sack? But there always is that 5 pound lumping hammer in the tool box.
