is this true?

[GaryC2.5td]

i read this on a saab forum just wonderng is it true and what are eccentric cone bolts??..

"Why not look for rims with a 108x5 or 112x5 pattern and use bolts with eccentric cones?"

[GaryC2.5td]

never mind sorry just found it ye should all have a look at this video im getting my self these straight away
changes ur pcd so cheaply http://www.youtube.com/watch?v=NVXljH8ms4s

you can also use aluminium alloy spacers (pcd converter) .. I use T6 mixture which is very safe..

Ya had them on my old jeep looked cool and all but spacers cause vibration in the steering. Plus they are expensive

I had those on my ford cortina 

Interesting these wobble bolts but not much movement and didnt realise you were allowed to drill or fill and re-drill  , learn something every day

Looks like that guy's spurs were out of shot in the video.

Filling and re-drilling? Opening out the holes with a countersink? Not on my car, thanks.

He completely ignored the centre bore diameter, too. Omega hubs rely on the centre bore to centre the wheel and take most of the lateral load from the bolts so they perform a clamping function only. A tight centre bore is why Omega wheels can be a challenge to remove sometimes. If the centre bore isn't a tight fit these loads are taken by the bolts and, if you use wobble bolts in addition, you have nothing to properly centre the wheel. Wobble will be the operative word.

I would only ever fit wheels of the correct PCD to any car of mine, avoiding all of these bodges, but then I've never felt the need to change the wheels anyway.

If i get this right then , so if you fit a spacer it comes with a centre bore  What was that about a 15mm minimum width on the spacer , would that be the new thread length for the re positioned bolts

if done properly, never..

the first set I had was steel and holes were not properly aligned..caused vibration .. but with second set I have no problem..

agreed.. also  center bore must be a tight fit..

Picture explained it

o i didnt realize wheel spacers could be got with center bore extruding thats prob why i had a bad vibration + the fact they were 3" spacers!! still might give the wobble bolts a go there not that dear and a wobble wont really bother me

I hope it would, as in effect, you are reducing the grip levels at part of the revolution, and putting other components under more stress.

there are various spacers(pcd changers)..I think suitable size spacers with appropriate bore size can be easily found in UK market.. 15mm spacer thickness can be used .. there are even 10mm s out there.. but not sure for their strength.. I used 20 mm width.. but mine were custom built..

+1

Under braking, you will lose efficiency momentarily per revolution causing your ABS to go completely mental and further reduce braking potential.

Your funeral.

I dono but I had the wobble in the stee ring in the jeep and that never affected the breaking nor did it affect the abs so don't think the wobble will still bother me
