Could someone please tell me what our stock wheel hub bore diameter is? I'm looking at different wheels, spacers, etc. I think it's either 72.6 mm or 70.5 mm, but haven't found any definitive answers by searching. Thanks.

did you ever find out?
 
At one point I measured, but can't remember. The stock wheels are on the car now and it's in winter storage. I ended up buying lug centric wheels with a large center bore, so it didn't matter for me anyway.

Yeah I found some wheels I like.
One has a 72.3 bore and an other has 83.3.
 
I’m sure if you contacted Budnik or CCW they would know. They build wheels specifically for our cars.
 
I'm measuring for new wheels and came up with 2.780" or 70.612 mm.
I cross referenced some rear disc brake kits that said the rear rotor bores were machined out to 2.780" as well.
