physically altering wheel offsets

[<--rYaN-->]

having ordered wheels where the offsets may force me to flare my arches, i was wondering if it was possible to grind the metal down by the bolt part of the wheel therefore moving it closer to the middle of the car


if an offset of 40mm is closer to the centre of the car than 30mm then isnt it possible to grind the inside of the wheel down slightly where it bolts on therefore moving it inwards??

is it possible, and/or hard to do??

in the same model wheel, do the wheels with smaller offsets just have thicker middle parts, or is the shape of the internal part of the wheel different altogether??

this is in the wrong section sorry, feel free to move it :)

Ryan, moved as requested. Now back to the matter in hand.

I have had some wheels modified like this, but they were used as trackday wheels, and not on the road.

I would be VERY carefull about doing this, as if not done properly the wheel goes out of true.

You need and engineering shop with a mill to remove the material, thats so long as there is enough material to be removed in the first place. Most of the time on split rims that move the mounting point to the outer rim, and not at the hub end.

Don't forget that removing material will also move the back of the spokes closer to the brakes ... If you need a radical change in offset chances are there isn't going to be enough room.

thanks for the info this is if worst comes to worst, the offset would only needed to be changed 5mm-10mm max, but that will be something i will have to look into if it becomes necessary!

at least i now know its not impossible,

thanks

Ryan, the most you want to take off is 5mm, 10mm will make the wheels very weak.

You would be better off rolling the arches and tying that before milling the wheels.

Worst case, being split rims you could just order new rims to attach to the spokes with more offset? Cheaper than complete new wheels!

I am sure on split rims this is how the offset is altered, or I will be flamed from on high by the Fish ;)

if this is the case would i even need to order new rims, couldnt i detach the existing spokes and move them forward or back on the rim or would their be very obvious marks from the previous location??

cheers

Max, wrong place. I dont flame on here, this is a source of information, not a place of 'How do I fill up my washer bottle!' ;)

The outer rim is not movible on split rims, they are made that way. Take a look the next time you have a wheel off.

The problem I think Ryan will have is that the outer rim will be ok, the inner part of the wheel (centre/hub) will still have too higher offset.
