Thread: D.I.Y disco rim off-setting..

I has been done many times before I believe. More than one bloke on the forum i'm sure. The short answer is that I would definatly get them done profesionally at a wheel/rim specailist - should be pretty resonable in price and little compared to the safety factor you are gaining. Another option you can do is get an old set of 16 x 8"or10" sunraysiers (most likely cruiser 6 stud attern) and swap the centers out so that you not only get a better offset but a wider rim to fit bigger rubber on

Good luck with it, i'm sure someone on here will soon post up a local bloke to you who will do the job professionally.

You really need a lathe and a dial indicator

Maybe set up a jig with an old hub to locate and spin them, either way, they need to be set up with a dial

it can be done at home, safely, if you know what you are doing...ie, bounce, run out and welding of corse.
i know for a fact that you WILL go through LOTS of gringing discs trying to split the welds and you'll be sick of being covered in sparks after the first rim......

i paid a wheel shop 30 bucks a rim to split the centers.
i did the rest myself with an old stub/hub assy and a dial indicator.

funny thing is the same tyres on the boost alloys had twice the amount of wheel ballance then steel D1 rims i flipped

Thanks guy's!!
Doesn't sound to bad, dad reckons the centre was easy to cut out, took a bit of a bash to remove the centre because they are so tightly fitted, he plans to make up a jig with an old stub/hub and go from there we'll see what happens

CHEERS TIM.

One more question...
How do you get around the Valve stem being on the inside of the rim (under the car), do you weld that one up and re-drill it on the outside or just put up with it on the inside?

I've seen both

Fill it and redrill

I recently upgraded my welder, so I thought I'd have a go at offsetting my spare set of Disco rims. I only wanted a 30mm offset, so I didn't need to spin the centers around.
One tip I can give is, grind enough of the original welds away so you can remove the center towards the inside of the wheel. This is because the outside of the center is actually tapered, so if you hit it out towards the outside of the wheel it actually gets tighter and tighter before it pops out......I found this out the hard way on the first one.
I made up a jig from MDF to allow the center to sit at the new position. We have a saw at work which cuts to 1/10th mm, so the jig is pretty accurate.
Because of the taper, when the center is moved back, there is a gap between the center and the rim. I used metal shims to center it.
When everything is in place, tack the center in.
I don't have a dial gauge or a lathe, so I simply fitted the wheel to the back of my Landy. I used a solid block and a steel ruler as a gauge, and span the wheel on the hub. Except for a couple of minor dents in the edge of the rim, it spun up pretty true. Actually, I wouldn't be surprised if it's better than the set I've had on the County for 10 years. It was certainly good enough to go back to the welder and finish it off.
