Would these spacers work

the idea of hubcentric is that they bolt to the hub then you bolt original bolts to the spacer...

i think the thread size is m14 on the wheel bolts you want 20mm max spacers for the rear only, i.e 10mm each side, any more is overkill....

leave the fronts asd they are.

need fronts aswell due to being for lambo reps so have to clear the brembo's thats why i was gonna get 10mm for front and 15mm for back

Not necessarily. You would only do this if the PCD was changing.
Hubcentric just means it has the required hole to fit on the hub as shown in the picture and a spindle to fit in to the alloy.

It is not a flat piece of metal that requires the tension in the bolts to hold it in place like the non-hubcentric ones are.

I doubt you would need 10mm each side to clear brembos? Depends on the ET of the lambo whels - why don't you get them offer them up to the car and see what you need, that's what I did.

I can't remember what bolt length I got, but measure the OEM ones and then add what ever mm spacer you have on to that. For locking wheel bolts I got a length that was in between the two sizes of bolt I required for the front and back (thicker spacer on the back)...

what i mean is the aftermarket bolts couyld be longer than the oem bolts, so make sure the aftermarket bolts dont catch the hub through the spacers.....

Fitted last Saturday 8mm/wheel spacers from H&R on the front and 5mm/wheel from the same provider on the rear.

They are "non-hubcentric" having a flat outer surface and a tapered hole to fit snugly the 57.1mm hub of the Leon/Mk4 platform. With 5mm/wheel can be used original bolts (8 threads to fit in the hole) and the wheel still centers itself on the original hub (~2mm of mating surface going in the hole of the wheel center). On the other side, 8mm spacers do not allow the wheel to touch the hub, hole being tapered and therefore wider at the base, hub protrudes into the wheel hole, but there is about 1mm of gap, and the wheel sits only on the 5 bolts (8mm longer bolts supplied by H&R as well).

Tried to center the wheel as carefully as possible by tightening the bolts in a cross pattern one by one.

In tests up to 140km/h there is no vibration coming from the front wheels, which can only mean the wheel is properly centered and balanced.

The question is: does the lack of contact with the hub mean danger of shearing the bolts at speed and wheel falling off? They are very strong but I must be sure.

Thank you,

you are correct. without spigot taking the wheel loads, the wheel bolts will now be workign in sheer, not tension, so yes, worst case they can fail, sheer off, wheel fall off and mayhem ensue.

Thats why wider spacers... which leave no spigot engagement, then put the wheel bolts into the wrong operation.. they are to clamp, not to centre the wheel or take sheer loads.

you have been warned
