Some years ago I read that brad Roberts was building these hubs that would allow us 4 lug guys the chance to use vented rotors. Apparently for some reason they can't be found anywhere. I have invested $$$ in aftermarket wheels and want to stay with 4 lugs.

Does anyone here have any information about these hubs? Maybe drawings or something, so I can have a set machined.


Thanks
Zach

I was standing in my garage this evening looking at a stock front rotor next to a modern toyota vented disk.

I was wondering if there would be any way to reproduce the hub & hat (bell) in Aluminum, then bolt that to a wilwood vented disk "blank" then make all that fit in with a stock caliper.

I remember coming across a thread about those hubs somewhere???? cant remember where though. But the poster said he had run them successfully, I recall that much. If someone could dig up a set and reproduce them, I'd be in for a set. If some enterprising individual could set them up with wilwood rotors and dynalite calipers that would bolt right on......well, I'd be all over that like stink on a monkey! The world needs a nice bolt on set up for the 914-4 strut. The 911 strut and brake conversion is too rich for me.

The machining was expensive and there just wasn't a big enough profit margin/demand to keep them going...plus Brad became a tad of a fuch-up.
He is gone from the 914 scene...done.

Used if you can find it or step up to the plate and become the vendor. (IMG:style_emoticons/default/biggrin.gif)
I bet Mike Mueller still has the files and would likely give them away.

I would do it. There are plenty of machine shops here in Houston. If we could get enought people interested, I'm sure we could get something going. I just need those drawings.

I actually have the perfect guy in mind that could build these.

Try to get a hold of Mike Mueller. He hasn't been around in a while, he's out of the 914 scene, but if he still has the files I'm sure he'll give them to you. He popped in to say hi last spring.

I did the 4 lug adapters on Kathy's LE back in 2009. Every time she drives the car she comments how she loves her brakes. 4 lug billet hubs with Eric's rebuilt restored Brembo aluminum calipers. This was money well spent.

I might still have the drawings around, I'll try and look in the next few days.

I have not spoken to Brad in about 3 years or so, no idea if cares if the drawing is released or not...all my current parts (2) I am making for Volvos I make the drawings available to the general public so I see no harm with these.

Wouldn't take too much work to get them drawn up again, I remember most of the details.

The 1st run was 7075, I really think 6061 would work just fine and save a good chunk of money on the raw billets.

I thought I heard something about Mark Hayes making them? markasap on here....

I've been out of the 914 stuff for ages, trying to get back into the game slowly....

Oh man Mike, I hope you still have the drawings. That would be awesome! I really want/need a set of these beauties on my car.

Does any one recall what rotor bolted to these hubs? I wonder how much time and effort would go in to reverse engineering a front rotor in order to make a hub? Obviously thats what was done in the first place. I gave up on the 911 front strut conversion. I was all set to go with BMW 320 calipers and stock rotors, and then I find out about this possibility.... damn it! You guys are killing me.

911 rotor ... something easily available from Pelican or ?

I want to say early 70's for sure, possibly the 20mm thick rotors from the 80 year models as well.

Dah.... I got, lol. But now I know why I have never seen them. They cost big money. Nearly $1200 for the fronts only. Not to mention I'm sure the shipping would be insane.

$188 US dollars each.... so less than $400 for the pair. (plus shipping of course)

Wow, I got lost on that website, I see now where I went wrong. Well hell, at that price I may go that direction. That's not bad. But I do still like the idea of replacing just the rotor instead of the whole assembly.
