The Offset Thread

[Fredericks Balls]

offset is the amount in mm that the mounting face of the back of the wheel is offset from the centre of the wheel.

so on a 9" wheel, offset zero would mean the back of the hub is exactly 4.5" from both edges of the wheel.

a positive offset is where the hub is towards the front of the wheel pushing the barrel in to the arch (less dish)

negative is where the hub is towards the back of the wheel pushing the barrel out of the arch (more dish)



low offset or better yet, negative offset is best for deep dish wheels for serious stance.

and just to ad, adding spacers lowers the offset by whatever thickness the spacer is. If youre looking for wheels that stick out to or past the arches, you want as little an offset number as possible, or idealy - numbers eg, -10. This applies to dish AND non dished wheels.




Maybe people who are not up to speed can gain the information they want here and it may serve useful to those looking to change their wheels too. And it goes like this...

[ste]

wheels: 19inch works rezax

front: 19 x 9 et+26 with 20mm ultralite spacers



rears: 19 x 10 et+26 with 5mm slip on spacers



offsetrs are very weak i know

plans are to bin the tires for much smaller ones to run stretch, flare front arches a bit and try fit more slip on spacers all round if possible, skyline arches are fairly small i was told so can only work with wat i can

using the figures you've given me,
an 8.5 wheel with et -12 and a 25mm spacer to start with (et-37),
and swapping to
a 9.5 et -19 wheel WITH the 25mm spacer (et-44) will leave you with
6mm LESS space between the wheel and the suspension,
and will bring the outer edge OUT 20mm

without the spacer you'll be worse off in every way.

put the original wheel on with the spacer, then use a ruler and guage how much space you have to play with on either side.
