dont do it, its dangerous, not worth the risk.

I asked rochford tyres about this on wolfrace icons, but the metal is too thin to safely allow this. If there's enough metal then the wheel can be milled down to a higher offset.

Takin 5mm of the mounting face is a lot the wheels are designed to be strong but this may compromise the strength specially under hard drivin, would you want one to explode whilst cornering at speed?

I heard the principle used is the same as when they take the cylinder head of your car and have it skimmed at an engineering works. The same bench is used. Apparantly the wheel get clasped on the bench and they skim some mm's off the hub section of the rim.

Its a bit hit and miss really. Different alloys act differently to this. Depending on the alloy quality etc.

Hey guys.

I have heard of places that modify the offset of an alloy wheel. Such as taking a few mm of the wheel to modify the offset from an ET40 to ET45. Is it true and is it safe? I mean the alloys is what's keeping you on the ground. Some alloys just are'nt available in an offset bigger than ET40. (Well, the alloys I want anyway!) Anyone got experience with this?
