My wheels were badly corroded and had some minor kerb marks.

Been looking for a new set of wheel for a while, but most of them are in the similar condition which means a refurb will be needed at some stage.

I got the full set powdercoated and diamond cut. What can I say, they look like as If I just bought the wheels brand new.

They weld the kerb marks with aluminum and then machine it down so after they cut them, the wheels are like new.

One point to note, I did notice a small chip already on the hub, not sure how it happened,I haven't spotted it on the collection, so probably happend in my custody.. I might bring them back, or maybe just touch up with the laquer.

Look great !

It's a real shame that BMW still continue to diamond cut wheels.

Had my 442Ms replaced a few months before the initial 3yr warranty was up but it's a pain knowing this set will start to rot in another 2yrs or so.

hiya, i have the same wheels and corrosion, which the dealer rejected under warranty because they have been refurbished before (even though they never told me this when i bought the car last year, but thats another story).

when you powder coat them what happens exactly, don't you lose that shiny surface finish? thats what i would like to preserve with mine, if possible.

also, how much did it cost and where?
would appreciate if you could take some close up shots and with some kind of light shining on them... if thats possible.

thanks

Has to be demand... they are a manufacturer's nightmare. Users like the shiny finish.

The fact they are not suitable for our climate seems to make no difference in many user's choice.

Nice job, shame you had them cut again, will not last especially on a refurb.

[SuperHamz]

They look superb, better than new IMO.

[N-W]

They look really good. I've been thinking of powder coating mine for a while, I want to get rid of the dreaded diamond cut.

No the finish is identical to a factory wheel. When I collected them I could not tell they were mine. They looked absolutely like a brand new product. The only difference is they use powder coat clear coat instead of a ordinary lacquer, so its more durable and resistant to scratches and so on.

First they dipped them in the acid to strip all the paint, then sand blast them and repair the dents, etc.
Then they paint them, then diamond cut them with a laser CNC machine and then clear powder coat.

I will upload some more photos in a few days.



Im based in Ireland so probably not good to you guys, but I believe anyone that has a Diamond cutting machine is able to do the job.

Also what was most surprising for me, that BMW and other dealers use their services all the time.

They obviously dont want the full job done, but just a diamond cut and a lacquer to keep the costs down.

So obviously when people have issues with wheels and so on, you'll find most of them are just refurbished to a high standard rather then getting a new set of wheels, and honesty it would be very hard to tell these arent new

Yep, they have to be choosing them in ignorance. They are ignorant of just how badly they last, plus about 85%of the cars I see round this way have expensive wheels on them that seem to get ZERO maintenance anyway. Thick with brake dust, never been washed and kerbed to hell.

The true cost of fashion over practicality.

Then add that many premium/performance cars are running tyres in a dreadful condition, or some unknown cheapo tyres.

Dunts comes to mind.

Was it an AUC?

If so, the wheels still have the 12 month warranty.

Looking good!
New centre caps to match too?

well, it was 20 months old when i bought it so had the remainder of warranty left, so over 1 years worth.

Then it's back to them.

For those wanted some close up pics of the actual diamond cut.

I put some ceramic coating on the wheels too, so will see how they perform in the long run!

[KCH1984]

What did you pay if you don't mind me asking? I need to get the full set of 21s on my X5 refurbed at some point and have been quoted c.£400 for powdercoating and then diamond cutting.

[RobUK]

Diamond cut wheels do look good when they're new - shame it's just not such a practical finish. Wonder if satin chrome would give a similar sort of look as diamond cut?

[Mani59]

Diamond cuts are an absolute pain to look after but as has already been said, look super when new and when properly maintained.

I'm having the diamond cuts on my E63 refurbished in a couple of weeks by a BMW dealer followed very swiftly with a layer of Poorboys!
