Probably shoulda oughta tooken more pitchers.
It's a nice picture of some nice brakes at least.
I like big brakes and I cannot lie.
I also like e30s.
Are you using the stock hub?
Points for being succinct.
Since it appears to be a success, I will do a wee writeup so I can be abused for using a table saw in my fabrication. I didn't really want photographic evidence if it wasn't going to work.
The table saw work sure did make me want a mill.
The hats are Wilwood, obviously. I had to chuck them up and increase the center bore by a millimeter or so. Rotors are typical late model pieces, readily available at your local circle track speed shop.
Hubs are stock. Absurdly long studs.
Go onnnn..
What's the required hub bore for an E30?
The caliper brackets took us 8 hours to make up out of hard foam then a couple of days to work up the courage to get after the 2.5 by 2.5 aluminum bar. A table saw with a good fence and a coarse carbide blade works... OK. I'm glad there was a snowbank just outside, so I could make a couple of passes, the cool it while making the same passes on the other one. It took 8 or 10 passes to cut an inch deep.
Hogging out the center to clear the center of the caliper needed a steady hand, a decent sliding fence and a keen awareness of where the spinning bits were. It ended up being good, but a half decent mill would have been a bunch easier.
I didn't take any pics, but I used a transfer punch to mark the holes for the caliper mounting studs. I cut two pieces of sheet metal and put them behind the pads to center the caliper, the clamped it down with a vice grip. Started with a small pilot after making sure my drill press surface was horizontal.
Next, drilled to 5/16 for a 3/8 NC tap. Then, using a thing I learned from watching Kurtis from Cutting Edge Engineering on YouTube (highly recommend) I started the tap in the drill press to make sure it started exactly straight in the hole. The tap will start to cut, then spins in the chuck, so you don't have to worry about breaking stuff.
Finished with the handle, then screwed the studs in.
Had to make some spacers with my old lathe.
Caliper fits. Didn't even have to bend a stud to make it fit.
Bracket is bolted to the factory holes with a couple of 10.9 grade 12mm bolts and stover nuts.
Rotor on, caliper on, and other than a couple of shims on final assembly to set the height, it's all good.
Just to make you guys really jealous, $550 from a tech high school that was shutting down its machining classes. I used it to make 4 shims, so not totally required, but hey...
$550cdn, too.
Need the same deal on a Bridgeport now.
I did the cage, too. If only I was getting paid my regular rate. Not even my car...
In reply to Keith Tanner :
Looks like 66mm.
Needs 16" wheels, or very careful shopping.

Then that may not work, or is not an E30 hub. E30 hub is 57.1 mm. All the 4 lug hubs for the E21/E30 are 4x100, Hub bore 57.1 mm with M12x1.5 bolt thread.
All the 5 lug hubs are 5x120, 72.5 or very few have a 74 mm hub bore, with an M12x1.5 thread. The heavier 7-series and SUVs use a the specs except an M14x1.5 bolt thread.
