1) I can 100% guarantee the hub spacers will fit. The hub bore for nearly all modern mercedes are the same with a few exceptions. Think of it this way, GLS wheels fit on a GL and vice versa. Same bolt pattern, same hub bore.

2) I have 30mm (used) and 45mm (brand new) spacers that are bolt on, hub center and wheel centric. Custom made aluminum with steel inserts. Pm me if you anyone wants to buy them.

3) I don't know the H&R part take out one lug bolt and measure the shank length and add 10mm to it and find a set online or call H&R if they have it.

4) Wheel spacer safety - http://www.maximummotorsports.com/te...s_spacers.aspx

Thanks. Measured, stock bolt length is 45mm. H&R does have 55mm 14x1.5 bolt available but only in chrome. Want some in black, any other quanlity sources? Don't want those from ebay, lol...

Quanlity hub-centric spacer/bolt + correct install/toqure = no problem I only want 10mm, otherwise I'd pm you already.

Yes, be very careful on eBay bolts. You will want bolts that are stamped 10.9 grade into the bolt itself.

BIMECC is one I trust:

I checked McGard and Gorilla - none have black in 55mm
Go to page 22 of BIMECC
I would get the 58 mm shank - an extra 3 mm will not hit anything, and it's better than being 2mm short (the 53 mm option).

You need a ball seat for OEM wheels and this does have a hex head of 19mm though. your oem ones i'm pretty sure are 17mm hex, so you need a 19mm hex lug socket.

these comes with washers, so they will stick out pretty far - i have a set (not black).

You can trust BIMECC lug bolts, http://www.bimeccengineering.com/factory

Oh I think these will work too:

I know Ichiba is a trusted wheel spacer brand, but I have zero idea on the wheel bolts.

These are ball seat too - but i'm pretty sure OEM wheels use a R14 radius vs a R12 radius. It shouldn't make a difference once torqued, but honestly something I wouldn't try. I'd stick with the BIMECC or just go with non-black bolts and live with it for peace of mind.

Looks like H&R 10mm is no go. Problem is the hub height. Went to the shop to pick up this morning. Met A 2018 E 43 is there doing spacer. The guy wants 10mm too, but the hub height on that car is at least 11mm. Even 12mm spacer still leaves a gap in between. 15mm clears. However, I think 15mm maybe a bit too much for a 450, even though I have the AMG look exterior. That kind of aggressive look is reserved for the real 63 AMG

Long shot, anyone happens to know the hub height on GLS?
