Not convinced the 5 stud system is required on Vx rims to be honest as if you look at the fit onto the hub, its bloody tight so must be pretty central (hence why they can seize on the hub). That or the bolts wont seat fully because there is no way you will pull the centre hole to an offset.

The biggest issue i find is the balancing method used (e.g. single speed on balancing based on a centre line) and the speed and lack of attention to detail by the operators.

My first inclination was to agree absolutely, but...........

The centre bore of the Omega wheel is parallel sided but it is chamfered at the end where a cone balancer would sit. It is quite possible for the centre bore to be accurate but for the chamfer to be off centre. That might explain peoples varying experiences with cone balancers

Find a fitter that can use a 5 stud balancer.

In all the years I've had wheels balanced they've never used the stud/bolt holes to mount it in their machine, it always uses the centre of the rim. 

Stud balancers are better as they match how it is on the car, not unknown for the centre hole to be marginally out, ot corrosion cause it not to sit centrally.

Never come across one

...then i guess no balance issues on yours...? They are not commonly used as they take longer to set up. Wims work on an accentric system with 3 or 4 for 3,4,or5 stud patterns, where as my guys have similar but work on a peg and hole system with every denominator for each makers stud pattern. So that might explane why they are not the default equipment at most tyre bays. Where as wim use nothing else i believe.

I have yet to have an accepable balance using the traditional cone balancer through the centre hole, which bares no relation to the centre of the wheel when fitted with the bolts! (relatively speaking of course)

...its the bolts that centre the wheel, so thats the referance to use for balancing. But usually only used if cone balance doesnt resolve the issue. Wim aside. 

WIM balanced mine, they didn't use (or suggest) the 5 stud system.

Its all they use AA

I thought I remembered H21 saying they'd now got a 5 studder, before you snigger too much

they had them at the first Wim open day iirc. Certainly on the second, years ago. Although relatively speaking, age wise, not that long ago perhaps... ahemmovingonquicklycoughcough....

Indeed, ever since opening their own centre they've had one.  Never went to Kiplings, though think Watford didn't

Also, from earlier as i was on a mobile...

A balance issue, imo, is  several repeated failed attempts to balance out vibration with no inbalance showing on the machine. Moving wheels for and aft has an effect but doesnt cure the problem, wheels inspected for dings, tyres for damage, balance checked again no fault found after returning to tyre fitter 2 or 3 times with even the boss doing the job himself and driving the car to witness the problem. Hubs checked as flat, wheel seated correctly. All on a cone balancer...
...so where does one go from there?  stud balancer system is where. Fits on the same machine, and instantly a discrepamcy is found. Wheels fitted, problem solved.

Thing is any fitter with said system will have found the limits of the standard equipment and recognise the need for something else. So by definition will know full well how to use thier machinary, and the limits of it. They may not have used the stud system, but will have it to fall back on should it be needed.
