Wheel Bore Size? Options

[GregAmy]

I hate starting topics for simple questions...but the search is defeating me.

What's the hub bore size of stock wheels? I'm looking to spec out some VTO wheels for the street car.

The Fuchs I'm running now (914.361.011.01) appear to have a 78.5mm bore (implying a 78mm hub size). But that's measured with a small scale, I don't have the correct snap gauges for that size.

I've test-fitted 205/50-15 Nitto NT01 on Panasport 15x7s from the race car but the offset is way too small (too far out); those will contact the right rear quarter on the street car, even when rolled. The race car has rolled inner fenders and "massaged" quarters; I think those Panasports are ET20 (hand-measured 122mm backspace).

I'm looking to fit a 205/50 on a 15x7 VTO within the street car's narrow body with only rolled fenders. Probably looking at ET35 if my calcs are right, 40 if I want to be safe (looks like I can move in that far safely).

Kinda just need the bore specs to nail it down...

Thanks!

Thanks! Yeah, I actually pulled out your sales order to get some specs, but the 86mm is not correct, it's way too big if you want the wheels to be hubcentric. It should be closer to 78-79mm. I'll pull a wheel off tonight and measure the front and rear hubs.

Noel is still working on his car, I imagine! he sent me some fit photos too. ET35 is going to be tight, but I think it will work on my car. ET20 is definitely too far out.
