Does this also include the stock of the 4-lug front vented rotors? I have seen them on a car before, so I know they exist, and I believe it was Mueller who did the CAD work for those. Would certainly be in for a set of those. No hijack and actually related. I think there may be more interest in 4 lug billet hubs that would allow the use the vented rotors. Have talked to Mark W and I plan to get him a set to be able to reproduce these. I already see some improvements thst can be mafe on the design. More details later. by +1 |

If a redesign is done, I would suggest changing the stud design. I have a set of these on my car and I've always been concerned about the screw in studs. In fact eventually, I'd like to talk to Mueller about this. For now, they work, they're safe, I'll use them.

If you think about it, the studs are more less what the factory now does with bolts, in fact I'd prefer studs with nuts over bolts alone. The bolt on rotor has a bolt pattern either the same or darn close to the 5x130 so getting pressed in studs would be a challenge with a 4x130 pattern. It might be possible and is something that can be looked into. |

It might be possible and is something that can be looked into. I have studied the design of the five lug hubs I have were I don't like it for several reasons. 1 There is an unneeded step on the surface that contacts the wheel and dos not allow the wheel to contact the full surface of the wheel as it does in a 911 hub design. There is a 5 mm gap between the wheel and the hub with no support directly under the nut that hold on the wheels. This could cause a wheel to crack and fail. 2. Hex head bolts were used in from the back side of the hub. I like that as it is more like the 911 hub design with a press in stud. The negatives are (A) To install the bolts the hex had to be ground to a round shape to sit flush with the surface and not interfere with the rotor. (B) if a bolt had to be replaced there is not an off the shelf part. © the holes were not bored deep enough to use a cap head screw. The simple solution is to use a cap head screw and bore the hole deeper. 3. The hubs were made to take 911 late type grease caps that are $50 each new. 914 ( or VW Beetle) grease caps are cheaper. 4. They are heavy. A lot of material could be machined away like is shown in Muellers design. 5 Cap head screws going into blind threaded hole are used to attach the rotor to the hub. I would use a through bolt and nut like the 911 hubs. Due to what I consider a serious design flaw I will not sell these hubs with out machining off the step. I have talked to Mark Whitesell about making both the five and four lug versions. It looks like it will happen. Attached thumbnail(s)

I had no hand in the 5 lug version, I only did the design work on the 4 lug version.
No idea why he has the step? Glad to see you being able to fill the need or want in such a small market! Just remember the more features of a part, the more it costs to make. |

I am sure working with Mark we can make a better, lighter 4 or 5 lug hub at reduced cost. The fix for these hubs may be to make a spacer that fits over face giving full mounting surface. If the step is machined off, the studs will extend 5mm farther and the wheel will be 5 mm closer to the caliper. If the studs extend 5mm more the closed end lug nuts may bottom out. Yes more features = higher costs. Simple is best. I like the pockets you have in your 4 lug design. |

Bruce,
I'd be interested in a set of 5 lug front hubs if you offer any more sets. Thanks, Dominic |

I searched and could not find anything. |

Bruce, I could use a set of rear 5 lug hubs and set of spacers for rear vented 911 rotors if you have them available. Let me know.
