wheel question [message #762841] Mon, 05 June 2006 06:40
cdagnolo  
Slightly OT, my daughters boyfriend has a Mazda 3 and he's looking at
aftermarket wheels and having trouble finding the proper offset.

factory: 52mm
he says most aftermarket wheels he's interested in: 40 to 45mm

Can you guys help him out with more than 'closer is better than farther'
please. Is this difference a problem or a minor detail? Long term effects?
Short term effects?

I don't think it matters but just in case, the bolt pattern is 5x114.3.

TIA

Thanks Christopher (has a nice ring doesn't it ;-) I'll check it out.

More input is welcome in the mean time.

The correct offset gives zero scrub radius and will preserve the
handling characteristics of the car. Less offset - which puts the
wheels more outboard - should only be chosen if a wider wheel will hit
the suspension using the normal offset, or if a wider track is felt to
be more important than maintaining zero scrub radius (Lanny may have an
expert view on the latter; both my wheelsets are standard Mazda so I
haven't tried it).

Otherwise, the correct offset does not change for different wheel widths.

MX-5/Miata owners have had this problem for a long time, because the NA
was designed for a 45mm offset and most aftermarket wheels in MX-5 sizes
were 37mm or thereabouts. The 8mm never seemed to be a big issue for
most people, so the difference between 52mm and 45mm probably isn't, either.

Lanny assumes, since there's a bit of a spread in offset among the OEM
wheels offered over the years, that small differences are not very
important. I wouldn't worry too much as long as nothing rubs and
everything fits inside the fenders.
