Quick stupid ? -offset.

Ok, quick question. a 43mm offset will move the wheel 3mm further OUT than a 40mm, right?

Or is it in? I've now heard both.

Anyone in here know if a 16x7 43mm will rub on a GSL-SE with 205/45-16? How about 215/45-16?

TIA

It will move it in, assuming the wheel widths are the same.

Rule is a higher numerical +(positive) offset moves the wheel in (again, assuming same wheel width), smaller numerical +(positive) offset moves it out. (ex an 18X10 +50 will sit 10mm further into the fender then an 18X10 +40 will)

I am not familiar with the 1st gen, so cannot comment on proper offset.

BTW, if you are in the negative offset range, then the rule is the opposite.

A smaller - (negative) offset moves the wheel in, where as a larger - (negative) offset moves the wheel out.

Very few applications that call for a negative offset (a widebody conversion for example, depending on the wheel width used), but perhaps this is where you heard the opposite.

When mentioning offset, the wheel width must be mentioned - other wise it's pretty much meaningless.

well stock is 14x5.5 w/ 40mm offset. That's a positive offset #, right? It's the same fitment as as teh older Accords.

There is very little clearance on the inside of the tire between it and the spring, so anything that moves it in won't work. Out I've got planty of room.....

Highly unlikely it's a negative offset. I probably should not have brought that up, as that very very few applications that use a negative setup hehe. Some times people just say a '40' offset, taking for granted it is positive.

So, assuming you want to keep the wheel size the same - 14X5.5", then you would want to go with a numerically smaller + (positive) offset number to push it towards the outside of the car. A 14X5.5 +30 would push it out 10mm towards the fender lip (and therefore give you an additional 10mm more space between the wheel and the spring.

If you go with a wider wheel though, say a 14X6.5, then you can no longer use these offset numbers (other then to calculate the correct offset for the 14X6.5.
