homemade DIY split-rims

[Sergey]

The only thing I can think of, is wheel balancing. They may look dead center to the eye, but fractions of a millimeter can be multiplied in amplitude, when they're spinning at highway speeds. I truly hope it works though, because they look fantastic.

what, no eye measurements are used ... rimrings aren't hanging in the air. They are milled in in the centerpiece, even the spokes had to be milled couple millimeters (flush mount? look the pic i drew)



and has less than 0,2mm tolerance to fit the rimrings in. BBS RS rimrings are manufactured to the same tolerance. It is a snug fit and i had to use rubbermallet to get the rimrings to the bottom. Three of them are perfectly balanced with 5-10g weights and one has 35g and that one has a welded crack on it... actually we managed to do two of these perfectly round and two shows some eccentric wobbling by micrometer, about 0,22mm if i remember right.

can you please post STEP BY STEP how u did this ?

Just look those snowpictures. It is pretty straight forward -> Cut off stock rimrings.

EDIT... it seems that Some Lorinser, AMG and BBS LM rims has 1/4" thick mountingface too. material grade is the same.

Coolest thing I've seen all day I think.

Interesting.

can you please post STEP BY STEP how u did this ?

i want to do this on my w126

Thanks! Many have security concerns and no doubt it might be an issue. my friend who is maritime engine engineer working at local ship engine metalworks (thanks for lending the mill) made some calculations that showed it would hold. The orginal made by ATS for Mercedes-Benz wheels are forged wich played a major part in this project. Cast wheels wouldn't hold.

I will glue the rimrings with structural bonding so they aren't quite split after that.

For a curiosity the mountingface is 7mm thick (just over 1/4") wich actually is 3-4mm thicker than the thinnest point on the stock ATS wheelbarrel (they are really light). I have had some japanese forged 15" wheels wich mountingface have been only 1/4" what was actually the main reason why i did continue this.

EDIT: and if the glue fail, then i will weld the rear barrel solid, so they will be 2pc wheels with greater failmargin.

oh snap!

this always scared me. its been in the back of my mind for a long time. figured id stick a hub in a 4 jaw chuck. Get it perfectly centered, bolt the wheel on then machine it how i wanted. curious to see how you went about the process.

i really want to do this to a set of XXR 002's. then widen to hell.

Im w/ matt on this one, this scares the living hell out of me. But hey if it works please go into more detail!!

[hinrichs]

omg this is so awsome if they hold up

[Mattphi]

I'll be honest, that scares the shit out of me.

[airkooled]

so freaking awesome i would be a littler weary of how they hold up!

[00bmw323]

wow...how did u cut them?? i would love to try this

[NELSON09]

NICE work!!!
