Wheel offset question

[britlude]

stock '91 15 inch 6.5Jx15 ET55, the et35 rims have the inside rim 1mm different from the stock plane, so ALL the extra width is outboard so the outside rim 'face' will be 1.5 inches further out from what you have at the moment

the ET47 rims move the hub mounting face 14 mm further outboard on the wheel, so the rims both move inward 14mm, so the outer rim edge is just under an inch further out than stock...


8x17 et 35 will stick out 1.5 inches from what you already have,

8x17 et 47 will stick out about an inch further than stock

Sorry all, just realised my calcultions were confused by a decimal point on my reply!! Schoolboy error.

I should have explained , the car is on route from Japan and I'm looking to have new wheels with uk legal tyres awaiting arrival.
I'm confident the rolling diameter etc is all within acceptable tolerance, but I'm unsighted as to how much gap is available from standard wheel to arch outer edge, to fill. I know et47 works.

On et35, the full 39mm extra width is all on the outside of the hub - I just don't know how inset the originals are and therefore if the wheel face and tyre will be legally inside the arch edge at that level.

I just don't want to order et47 and then have to fit spacers!

Trouble is I know nobody locally with an NA1 NSX with standard wheels to check.

Thanks for the help/input

Hi Ian,

Where are you based? There should be someone in your area.

[Ian_S]

I'm in Newcastle upon Tyne.

Yep, that’s me out. I’m in Somerset :-) I think most owners live in the south-east. There are a handful of owners where I live.

Hi Ian,

Pity we didn't get a chance to meet at Silverstone, and nice to hear of another owner "up north". I don't really know much about wheel offsets ether, and as I have the wider front wings, I was asked if I wanted spacers fitted, but i'm not keen on that idea either.

Cheers
