Ilario - Yes, I can make duct plenums for your Brembo brakes - I'll need 2 dimensions:
- The inside diameter of the inner rotor cheek
- The depth of the rotor, from the face of the inner cheek to the hub mounting face

PM sent on cost and payment

Thanks Alan. Pricing is fine. I'll try get those dimensions to you within the next five/six days or so.

PM sent.

See updated pricing on the LS1 brake duct plenums, post #1 of this thread. They are the most labor intensive to construct, and I would rather discontinue them since most users now have moved on the C6 or Wilwood or Stoptech brakes. I will leave them on the available list for a while, but at a higher price that reflects the build labor. I hope that this will shake used sets off of garage shelves and back into the market.

None of the models of duct plenums will fit the latest Timken wide body hubs. I have tried to develop a reasonably efficent manufacturing process to accommodate those hubs, and it is not happening with the tooling I have at my disposal. I recommend SKF hubs.

Alan, I know we talked about the SKF hubs a while back.

I've had some setbacks on the car so still inconclusive if there is any significant improvement over the Timkens, but at this point I can still recommend them as "equals" to the Timkens, especially considering you can get them with warranty at Oreilly under their masterpro line now.

Oreillys "Precision" brand has factory dimensions and is working well for me.

Different parts come in the box, so far a MOOG and a National. Both have done better than any Timken I have run.

Yeah, but if you look closely they all come out of the same factory in Korea that SKF get's theirs from. Everything about those hubs from the pics you posted are identical to the SKF I checked out at NAPA (under their most premium offering).

The nice thing is the bodies are smooth, narrow, and machine. The Timkens look like someone melted up some British cars and poured them into a mold made of leftover cement or something lol.

I just want to get through Hallet with what I have, then probably convert to 3rd gen style hubs over the summer.

I've replaced my hubs with Timkens the last few years, and replaced one just a few weeks ago. How can I distinguish widebody Timkens?

Likewise, I went with the Timken hub during my last swap and would love to know how to determine if I have the "widebody" version.

Guess I could order a set of the ducts and if they don't fit, then I know!

All hub bodies used to be cylindrical in shape, then Timken came out with a slightly tapered, wider at the bolt flange, version. These would fit the duct plenums with a little trimming. Then they changed to a more wider at the bottom, more tapered shape body. These do not leave enough flat space to adequately anchor the duct plenums, and in use do not show any substantive improvement in service life over the earlier versions.

Thanks FFB! Winner here....one OEM front hub and one newer "widebody" Timken.

Any idea if the SKF hubs & adapters are compatible with one of these plenum kits?

Jim - Yes, I make duct plenums for the Dulaney brackets, just need to know what rotor and caliper you are are using.

Cost is $355 + $16 shipping via USPS Priority Mail.
