9J Wheel Offsets

[AceOfHearts]

For you guys running 9J rear wheels what offset are they?

[SILICONEKID345HP]

I thought some cutting is needed for 9j.

Gotta pair of 18x9" in the garage and can measure.

Yes, you will have to trim the arches.

I run 265mm wide tyres on these.

Ok cheers. Does 'trim' just mean trim or fully cut out the inner arches and re-glass for added clearance? Any pics?

[phazed]

It means trimming just inside the lip of the wheel arch.

If you feel the thickness of the wheel arch lip you will find it is over an inch in thickness. This needs to be trimmed back to about half the thickness.
The fibreglass here is double skinned and when the sliver of of fibreglass is cut away it can be made good with a little fibreglass resin and matting.

It really is an easy job and both arches can be completed within a few hours.

Awesome cheers

Does anyone running wider wheels have some pictures to share?

Your skills lie with Silicone, Daz.

I used something like this specifically for cutting fibreglass. It doesn't revolve, it reciprocates and is very safe to use.

Would they be better off going inward slightly .

Running 18x9 with 38 offset..very very slight rub on full compression

Not the best pic.. holed up in the garage

[QBee]

Is the slight rub on the inside or the outside of the tyre?

[fluidslvr]

Rub is on the outside of the tyre

Well, 38 offset is 5mm further in than the standard 33, so it sounds to me like the tyres are simply too wide for the wheel arches

[SILICONEKID345HP]

The tyres may be catching on the outriggers. Lift the car snd see.

[fluidslvr]

Yeah are probably too wide,but thats how i bought them(used), so can live with the very slight rub occasionally

When i need some new rubber ill try a slightly narrower one..

Not catching the outriggers

[QBee]

If it's only slight just raise the rear ride height a tad

And /or add some camber on the rears if it's only just touching.
