Redrilled stud pattern
tomdelta - March 11th, 2015 at 05:14 PM

Would anyone please be able to tell me, if having hubs that have been drilled for a different stud pattern is roadworthy or not in Victoria. My 72 super bug has discs that must have been blank and has 5x100 pcd stud pattern drilled in it, and the drums are original four stud that have been drilled as well. The front also has about 5mm spacers. This was like this when I bought the car. Thanks in advance.

G'day

Spacers are illegal unless they were part of original manufacture
Porsche ran spacers and I know of people that have 944 rear trailing arms installed that have managed to get them signed off

drums and hubs are suppose to not have multiple patterns

generally that means single bolt patterns

Again - i have heard of people getting a redrilled drum / rotor through by having a stud flush in the unused pattern

I would not use a 4 stud VW drum / rotor that has been redrilled to 5 or off set 4 stud.
The VW drum / rotor is "webbed" for thickness on the 4 bolt holes. Moving away from this puts you in a thin area that aint safe

Thanks Bizarre, yeah sounds like more trouble than its worth, might go back to 4 stud setup and try and find some wheels I like. Thanks for the reply.

If you already have 5x100 front discs you would be off to get some new rear drums in that pattern.

There's no nice wheels in the stock 4x130 where as 5x100 being Subaru and watercooled VW there is heaps of choice.

If the spacers are not removable, and they do not increase the overall track by 25mm (track is measured from the centre of the tyre, not the outside edge). So the spacer must have loctited screws that are countersunk. This is to eliminate the possibility of a wheel change becoming an accidental forgetting to fit the spacer. We work on a lot of cars that had them fitted from factory at our work, and even the ones that do not have them fitted originally pass engineering if they are fitted correctly.

Thanks Joel, yeah your right, been looking for awhile but couldn't find any 4 stud rims that I like.
