Cheapie Chrome Center Caps on Ebay - Fixed!
The plastic of the 1980’s caps on my 560SL was very different than the plastic that must be used on caps that will have vacuum deposited chrome. It is stronger but it is more brittle. My theory is that the Chinese modeled the new plastic caps based upon the old ones, the tabs stick out more than they should and will break when installed..
So, how did I “fix” this? I have a surface mount rework station (for soldering) with a heat gun on it. Using a narrow nozzle for 250 degree C heat (probaly more than really needed), I heated the base of the tab just enough to get it soft and bend it nearly parallel with the outer diameter of the cap (it can stick out a LITTLE more). It iis a good idea to remove the wire spring first. Bend the too much and the cap is loose in the rtim? Bend the tabs back out a bit. You have to do this 12 times on a set of these. Unless you hit one amazing pothole that will destroy your wheel anyway, they will stay in once installed.
You might be able to duplicate these results with a shop heat gun but I caution to get only tthe areas shown hot. Perhaps aluminum foil shielding would work here. Maybe a butane cigarette lighter would work with proper aluminum foil shielding.
Even if you bought a $10 mini heat gun on eBay as opposed to a surface mount rework station you would be wildly money ahead on these caps compared to OEM with this modification.
As usual, information only, don’t burn yourself, not responsible if you do - so. don’t, YMMV, etc.

SMD Rework Heat Gun
Well...I like it. Also note chrome door handles (ABS, from eBay). Pretty tricky to install but good.




also have MB logo tire stem caps for roughly the same amount. Lots of little and cheap things you buy for the car this way. I never did the illuminated front logo though. Found it was just too bright for my taste. Wife’s car has it as genuine MB and is far more subtle.
Plug and play with no issues regarding not fitting tabs.

I intend to put a potentiometer in line with the star lighting and adjust it to suit my taste, and then replace that with a permanent fixed resistor. I agree, too much is too much!
