So - I found a mint set of used 19s for my CL... (Wheel Bolt Size Question)

[Zally]

Hey Guys...
Apologies for another question...

Since the other thread where I was looking for OEM rims for my CL500 - a perfect used set came on Ebay and I snapped em up...
They came off an W221 S63...

Trouble is I went away without being able to fit them cos the bolts holding on my stock 17s were too short.
Trying now to source the right lengths...

I need longer rears for the extra width (obviously), but I'm looking for the right length for the fronts.

For a rear 9.5 width, and a 8.5 front?
What length of wheel bolt would be correct?

Save me a third attempt please

(PS: also what MB locking wheel nut set do I need, and do I need two sets of different lengths?)

Thanks, Guys!

Pic attached - it almost looked so good

Edit. These bolts fit both front and rear

Thank you! So the same length bolt front and rear regardless?

The issue we had putting them on was that the long bolts the chap had from his S63 worked fine to fit the rears,
but those same length bolts were about 10mil too long to fit the fronts.

My W216 has 20inch AMG wheels the total wheel bolt length is 68mm for front and back.
it's a bit strange that your wheels can't have the same bolts fitted all round, are the wheels thicker/thinner?.

Yeah, I've all the same size 48mm OEM bolts on order now.
Couple of things was confusing me...

I hear about the 68 and the 48, but when someone says a 48mm bolt to me I imagine the length of the bolt shaft is 48, and it is, but some vendors are saying 68 (but thats the total length...) and I thought 68 (shaft) way too long, it can't be that, so was a bit confusing,

So what was a 48 in my head is actually the 68 you're using all round.


Another thing that confused me was my "stock" 17's I now suspect didn't come with the car after all, and the previous owner put shorter bolts than the standard ones that came with the CL to fit those.


Lastly the front back thing, just my ignorance!

 

[AMGeed]

All bolts are measured from the underside of the radius to the top of the thread by manufacturers.
Its easy to think its the whole length including the head (which is around 20mm)
Glad you have the correct ones on order.

OMG! That paintwork! Silky shiny smooth!

Can you post up more pictures please so we can all drool. And a 13 year old motor!

Also nice to see a wise man with a standard powder coat refurb. I went diamond cut in August and was regretting the return of under lacquer corrosion by january

Looks amazing!
Hows the ride on 20s? What's the tyre profile? 35?

 

[Zally]

Sorted

255/35R20 front and 275/35R20 on the rear
The ride is very smooth, it's a bit harsh if you hit pot holes, so I try to avoid them.

I did plan on getting them refurbed professionally but since we had the lock down, decided to do them myself, it's not quite as good as the tyres weren't removed, but good enough.

not sure that all the photos worked, maybe I put on too many.

Very nice... 5 spoke is the way on these!
