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.  :y

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.

Must admit, had no problems with mine, since WIM balanced them.

Ok, once more for the hard of understanding ;D

If you've not had a balance issue where a normal cone balancer has not been accurate enough to eliminate vibration, then you wont have had need for, or have encountered, a 5 stud balancer.

If however repeated balances fail to solve the issue, the more accurate option is the 5 stud system. Hence the advice given.

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.

I'd tend to agree with that. 9 times out of 10 in tyre shops I've been to they seem to spin the wheel up, add a weight where indicated and chuck it on the car. Don't even bother to spin it up again to check that it's worked.

Sorry, don't understand, could you be more specific please ::)

To be honest I have had balancing issues a few times and it was always sorted by finding somebody with a reasonable machine who knew how to use it.

...thats not a balance issue though. Thats a "technician" issue.

I reckon there is too much scope for it to be off centre, esp as every GM alloy I've seen corrodes like Omega bodywork ;D.

Only takes for a bit of corrosion to sit on the cone for it to then be off - never seen a tyre place clean the centre before balancing.

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