Need a view please form those that understand wheel offsets...

Stock OEM offset:

Front Wheels: ET 41.9
Rear wheels is ET55.3
Centre Bore: 57.1

Question is will a set of R8 wheels with the following offsets fit ok?

Front Wheels: ET42.0
Rear Wheels: ET50.0
Is the centre bore likely to be the same? I.e. same hub.



I am wanting a set of winter wheels and tyres and have the opportunity to buy some R8 wheels, but not sure if the difference in rear offsets will cause any issues predominantly with brake Calipers clearances and protrusion from the wheel arch.

Anyone have experience with aftermarket wheels and what sizes do work?

Thanks in advance.

The R8 rear wheel have a smaller offset, so they will ‘stick out’ more. The centreline of the wheel will be 5mm further away from the suspension.
If they have the same rim width then the outer face will be 5mm further outboard, but if the width is different then this will affect where the inner and outer faces are relative to the car.

What are the rim widths of your wheels and the R8 wheels?

My car:

Front 8.5
Rear 11.0

Wheels I am looking at:

Front 8.5
Rear 11.0

The wheels I am looking have good tyres on them with identical profiles to my car namely

Front: 235/35/19
Rear: 295/30/19

ETA: I have ascertained that the centre bore is identical at 57.1. So it really is all about the 5mm offset difference and whether that matters.

Yes, significantly. The wheels I can get are as new with winter tyres that have good tread and are not old (According to the DOT markings). They are the the right colour and I like the style.

Also, finding decent Lamborghini OEM wheels is not easy. My ones are Scorpius and come in at about £3000 each! There are sets on eBay etc etc, but these in the main are a bit rough round the edges and still significantly dearer than these.

Lambo tax and all that...

So on the off chance anyone is interested, I ended up purchasing a mint set of wheels with brand new winter tyres.

The wheels are Audi R8 V10 wheels, which I have not seen on too many cars in this design. I am told they were available as an option on the run out editions of LMX/GT. Personally I like them and I think they will serve well for winter use, as they are not overly fussy and can be easily cleaned.

The specs are:

Front:

19 x 8.5J ET42 with 57.1mm bore. These are pretty much OEM Lambo spec, the Lambo ET is 41.9. They clear the calipers on my CCBs just fine.

Rear:

19 x 11J ET50 with 57.1mm bore. The OEM Lambo ET is 55.3. The visible difference in fitment is so marginal, you don’t notice. Again, just went straight on no issues.

I have used the titanium wheel bolts from my Scorpius OEM wheels, which again, fit just fine.
