First, yes i have searched. Looking for info on running a wheel spacer on a 2011 E550 $matic sedan. I want to run 12-15mm. I bought some 12mm ones that would work on the rear but not the front, the step hubcentric ring interferes with the long snout. Has anyone run larger than a 5mm spacer up front?

For front you need H&R p/n 24556659 (12mm spacers) or p/n 30556659 (15mm spacers).

threeMBs or fellow forum members, I need your infinite wisdom. Is it possible to run a 10mm front and 5mm rear on one of these? (4matic). I recall at one point reading there was a minimum thickness needed to run in order to retain adequate support....

Also, does anyone know the length of the threaded portion of the stock lug bolts? are they tapered or round? (haven't had mine off for a while and can't recall)

Cheers

IMHO one can not run 5mm rear spacers safely on any of MB cars since the rear hub on most of them is about 7mm and the remaining 2mm are not enough to (even close to safely) seat a wheel on.

Stock W212 bolts are MB ball(round) seat (R14) with just under 28mm thread length.

Thanks threeMBs, they will be here tomorrow. I will post up when i get them installed.

Can't answer the spacer question, but the stock lug bolts are round. I also recall reading on here about a minimum spacer thickness, and I believe it was 10mm, but don't take my word for it unless others can chime in.
