I knew the front end was different but I was assured these wheels would be fine so gambled......Should have trusted my instinct
What about hubcentric spacers? Had a lot of success with them in the past, Eibach and H&R are pretty bulletproof. Just need to work out the size
If Hub-centric spacers are legal in your country, then by all means H&R and Lorinser sell them iirc.
However, I believe you're then restricted to running some very oddball offsets to get the correct offset.
when your 300SL was delivered, it came with an ovaloid 15-hole wheel referred to as Gullideckel (manhole cover) because they eerily ressemble the manhole covers in Stuttgart.
Those wheels measure 15x7 ET25. They have a larger diamter to the pre 09/85 built 107's, because of the updated brakes, spindles, hubs and control arms.
To fit a wheel to match, you need to keep your offset appropriate for the width of the wheel (i.e. match the factory) to prevent rubing on the guards or swaybars.
Basically, you are looking at running a 16" rim in restricted offsets, due to the inability to put more tyre 'inside' (higher offset)- doing so results in less clearance to the LCA, UCA and swaybar. on the rear it is mostly the inner tub and the swaybar, which happens to be an integral part of the location of the rear hub. So rubbing is a big no-no on the rear bar.
when you up the diameter to 17", you gain more freedom, due to the inside diameter of the wheel offering more clearance. This means you can go to some higher offsets and tuck more wheel under the front.
Typically, you do not want to exceed something like a 17x8 ET28 on the front, because it reduces the scrub radius and makes the front a little more twitchy. You can go to 18's - I did for a while, but the huge wheel doesn't quite suit the car's styling. I ran some w211 E63 staggered rims and they rubbed when bottoming out under compression on the rear and on full lock on the front bar, quite a way forward on the front bar too, but the offset was ET35 and the tyres were WIDE.
For reference, the Penta offsets for Gen 2 are identical ET11 for the 16x8, but the entire centre is offset to accommodate the spacing for the calliper. They look 'interesting' and do not match well in a staggered set.
I understand your love of pentas. Most 107 owners agree they are a perfect period correct wheel. Genuine AMG Pentas are very rare to find these days and fetch stupid $. I recently offloaded my widebody set to a gentleman in Melbourne, and sold them for a fair bit less than I could have, but he has a widebody car to put them on, so he was a deserving custodian.
You have other options for period correct wheels. AMG Aero styling 1 monoblocks, in 16x7.5 ET17, or 17x8ET11 ( the 17's have a flat centre face, 16's are slightly curved).
AMG Aero styling 1 3pc staggered (OZ-Racing) in 17x8.5 ET18 front & 17x10 ET17 rear, or as an example I fitted later w210/211 AMG 5 spoke rim in 18x8 and 18x9 with an ET approx 35 - I don't recall exactly but pretty sure it was ET35 (can rub on the upper shoulder of the inner tub on rear under full bump and on the front bar at full lock, but you have to be at those extreme angles to notice)
Lorinser LO's - yep, but let me state at the outset... good luck finding a set. Also, the front is a problem, just like your pentas, because they did not manufacture the wheel with a suitably deep hub face to allow for the calliper clearance. Most people who are desperate to run these rims end up with spacers and gamble on that, but they never quite look right when in the wheel tub for some reason. I have not ever seen a set of the alleged 'ET23' fronts fit without spacers on the front of a 560, but there is rumour of this alleged rarity being the cure.
Once you go to 18" diameter, you alter a few things. You have clearance to just about run anything from an ET0 to ET35 depending on your chosen width, and you have pretty much taken care of the calliper clearance issue on the front, due to the nature of modern wheel manufacture. Not all rims will be suitable though, you need to take into account the actual overall mass of the wheel and tyre you are replacing, as unsprung mass increases on a 107 can be felt and are a negative handling trait overall, especially on bumpy roads.
Yes, pentas are cool. I even stuffed a 16x9 ET0 on the front of Lurch years ago and the 16x10 ET-12.7 on the rear, just for giggles. The rear err... yeah no chance without cutting a LOT of sheetmetal, but it could have been done...
Life can get interesting fitting wheels. Especially fitting the wheels you want. For a wheelwhore it can be an endless pursuit and you end up with dozens of 'spare' sets under your house, gathering dust - and ready for when you have a change of mind about how your car should look. It's also a lot of idle cash just sitting there unused.
There used to be a pretty good thread on here where people posted pics,(found: https://www.benzworld.org/forums/r-c...ol-wheels.html
) but I believe the demise of photofkit and imagefk etc put paid to the thread consistency. A Google search will pretty-much net you an apreciation of the many and varied R107 combinations people have shoved under the guards - not all are tasteful, but beauty is in the eye of the beholder....
Take a deep breath and be patient. You will find something that you really like, which fits without issue.
