Reply With Quotebeing Honda wheels I'm not sure they'd be +25..
although with a 5" backspace, that'd put them at a +12 offset. Maybe they're actually that low, being a drag wheel, but it's odd seeing a honda wheel that low of an offset.

If I had the cash I'd jump on these,
13x8 estimating +25mm offset from what the listing says.

its perfectly normal for hondas to have low offsets on drag wheels, for obvious grip reasons being fwd and pretty much dragging everything behind them..., plus on the drag strip there isnt any law about poke......
every civic ive seen with slicks have wheels that poke

You make a good point Dom!

sorry I thought to calculate the offset it was (back spacing - half the width of the wheel)...guessing that formula is wrong... I did say estimate
+12 is still workable on a mk1 isn't it?

back spacing is calculated hrom the mounting hup to the inner lip's end, so from the mounting hub, its 5" pushed inside
so to work out offset, you measure from bead lip to bead lip, half that, that will equal the center of the width, then you work out the ET by how far the mounting hub is compared to the center of the wheel....

Offset (wheel) - Wikipedia, the free encyclopedia
okay I'm confused, not the only place that says offset is calculated like the formula I used.
obviously all depends how the backspacing is measured, if it's to the out side of the wheel it would be wrong, but mount hub to outer bead (which I assumed) would be right. thats how I got +25
If that is the wrong way it's lucky I never win ebay auctions cos I'd have a ****load of useless wheels laying around
Found another formula
[Wheel Width / 2] + [Offset] + 6.35mm = [Backspacing]
4" + ?? + 1/4"= 5"
101.6MM + ?? + 6.35MM = 127MM
107.95 + ?? = 127
?? = 127- 107.95
19.05
Means ET +19.05
different again
