Ok there is a note about Diamond wheels being lug centric and the center hole can not be relied upon to be exactly centered. SOmething about how the center section is stamped and cut.
Anyone got an idea of how to balance one of these. I am going to put some Hankook RS-2 tires for the street on a set of 15 x 8 Diamond pro wheels. Wonder if I could use a spare front hub mount up the wheel and get it on a balance machine? |

Wouldn't the ya-hoos down at the tire store know what to do? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
Tell them is a NASCAR wheel and they'll bow down to it. |

Are you balancing these or is someone else. It should be no problem for your average tire shop. They should have the fixtures for it. I would call first though.

He's gotta hope they have an adapter for 4x130. Thats probably pretty unlikely. I recall someone saying they just balanced them on the hubs and it always worked fine. Try searching, there may have been a thread about it.
Also, you could probably have the hub machined so it is centric. |

Yea after they get done scratching thier asses and bumpin thier heads the just walk in a circle picking thier nose. Going to do it myself at a Military base hobby shop. nice Hunter balancing machine. I suppose I could get it close enough with a good old school bubble level. Bubba has one in his shop that looks like it still works. Objective is be able to drive to events without the whole car shaking apart. |

Iwas gonna suggest static balancing as a last resort.
If you take your time, you can get really good results -ut finding a bubble balancer to use is getting really hard |

Hi Joe,
I have 4 sets of Diamond Racing wheels for our track cars. In the SF Bay Area, I could not find a wheel balancing place that had a 5x130 hub. A high end shop said they could make one for me for $500. Needless to say, I had them balance it on the hub as was previously mentioned. So far no issues doing it that way as far as balancing, although I do have a little shake in my front end at 80 to 90 mph. But that's probably due to the flat spotting of my front tires going too hot into a corner! (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) I think you're gonna have to come up with your own solution. I'll be watching because I need one too. Bill P. |

So maybe I am thinking of something else. What is your definition of "on the hub" ?
Like when it in on the car and they do a dynamic balance using a roller? Those are supposed to be the best machines. I am positive there aren't any around here. My idea was to use a spare hub with all the bearings and such pulled out. mount up the wheel using short lugs and put the whole thing on the balancer. |

Have you looked into machining the wheel hub so it is hub-centric? I assume diamond doesn't guarantee that the hole in the hub is exactly centered in the wheel, but the lugs are. Machining the hub seems pretty viable. |

Using the hole in the center of the wheel like any other wheel. |

If you call around, you need to confirm they have the correct adapter for our wheels..
They dont typically. If you find a VW shop..they will have it..most of the vw wheels need the adapter...they are not perfectly machined... I also found that the Porsche wheels, namely the fuchs...can be balanced either way..they are pretty well balanced and the hole is centered. I had some rivieras that show 1/2 inch out of round if you center them up on the machine via the hub... I would say that if you can make a hub work...SHOW ME HOW>> I have three cars with this issue..I would make one in a heart beat...just bring it out when its time for tires... Rich |

yah yah yah..pretty wheels ...
Hey did Aaron mention he got new wheels (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) I love the look Aaron, almost makes me want to get a five lug setup....almost. I would be curious how they do on torun in etc... I never like big rear, small front wheel setups.. But, I suppose if you get the right tires etc it would work out. rich |

Joe, believe it or not I used to balance them like a normal wheel. Just slap it on the balancer. I ran them on the street and never had any imbalance. Give it a shot and see what happens.

Theres something called a pin plate (or at least thats what Coats calls it). Its a disk with lots of holes and pins that simulate lug bolts that press into the lug holes. Our coats has 4 different plates with like 32 different arrangements for different bolt circles.
(IMG:http://www.myerstiresupply.com/PICTURES/image_gif/71382.gif) looks like that |

matt, thats cool. so i take it lots of wheels are lug centric and not hubcentric???
why is it sooo hard to put the center hole in the exact midde tho? (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) |

We use the pin plate to be absolutely sure. It has to do with manufacturoring and tolerances. Remember, the hole in the center is there just for the centercap. The car actually uses the lug holes. Why should you balance around the center? Machining isnt perfect, and when talking about such small tolerances as seen in balancing of wheels, ya need to be perfect (to a quarter ounce). |

Why couldn't you just use a extra rear hub. Sure solves trying to find a shop with 4X130 adapters. It looks a lot like the pin plates in MattR's post.
Oh well just my $0.02 van914 |
