1mm. difference with wheel bore
Between my hub and wheel bore a 1mm. difference exists. Should I be concerned? I was told that to correct problem the wheel bore needs to be enlarged so a 2mm hub spacer can fit. Apparently the spacers are not made in 1mm.

yes ... wheels are hubcentric for a reason. the lug studs and bolts do not have much horizontal rigidity and strength compared to the longitudinal strength. They are not designed to support the weight of the car that's what the center hub is designed to do.

That is what I was told yet I am getting other opinions elsewhere, especially from the company that had the wheels made as well as the tire guy himself although the shop owner has different opinion. There is no vibration and I was told that in that case I am good to go. My wheel installer wants another $250 to bore, and cost of hub spacers plus mounting again.

They don't want to be bothered with you......
I'm going through a similar situation, but with my 4x4. The OE wheels are at the absolute minimum for the tire size, therefore, a bit narrow, IMHO, for the tires. I can get wider rims, but NONE of those on the market are hubcentric, and furthermore, they all use the "push-in" center caps, which pactically make hub centric rings impossible to use.

Being an "old timer", who was weaned on Cragar SS and Appliance "Turbo-Vec" wheels, I know that "universal fit" wheels were at one point in time, the industry standard. They allowed a wheel maker to make 3-4 wheels, and virtually fit ANY American muscle car on the market. It sometimes scares me to think about the non hubcentric, multi-lug pattern wheels that we used to regularily drive at 100+ MPH

Pretty much finished my homework on this issue. Seems that I was getting worked up for no good reason. Guess the wheel shop saw a good opportunity to pick up some xtra work.

I don't know about that... 1mm is 0.039". That is a fair amount of clearance around the hub. I have a set of BBS LM wheels for my '01 Vette, and they are TIGHT around the center hub....I struggle to get them seated in the spring, then off for the winter. THAT'S hubcentric!

1mm is nothing to be concerned about
