Wow apparently in my hiatus from this site the w124 went from hot hotness to old and ugly. I have a 92 300E to which I have added a set of H&R lowering springs, bilstein sports, and some AMG 055s (offset 35mm) in 18x8 wrapped in 225/40. Forget what everyone else says, w124s look absolutely amazing with a small drop and some nice wheels and it is absolutely worth the effort for both asthetic and performance reasons (my car was totally transformed by these mods from a sedate sedan to something that can easily put a grin on your face.) That being said at your mileage your bushings are going to be on the way out if not already shot but it sounds like you have both the means and the will to take care of this issue when it arrises.

Now down to business. On my 18s, an offset of 35mm did not rub on the inner fender wall but did rub on the fender lip as well as on the fender lining during bumps (front wheels only.) To remedy the latter make sure you change out your bump stops when you are installing the new shocks and cut them a little longer than half to compensate for your drop. The former is a tricker issue. I was forced to roll my fenders within 2 days of the suspension modifications because of the excessive rubbing. I used the baseball bat and heat gun method with great success and it took me about 4 hours total. In addition, I have installed AMG fender spacers up front. They are basically a set of polyurethane spacers and longer screws that push the bottoms of the front fenders out to give you a bit more space. They are hard to find but I am confident you could do just as well with parts from your local Home Depot. Finally, your rear camber will be a mess. I was almost 4 degrees negative on both sides after lowering. I have installed a set of of Benzboy camber arms which have worked very well except for a lubrication issue. My arms do not have teflon coated end joints and therefore must be lubricated periodically to avoid an obnoxious squeaking. Speedybenz does make a superb set of teflon-ended camber arms which can be purchased for less than $300. Your front camber will be slightly off but nothing to worry about, I am currently maxed at a little under a degree.

I have had my 124 for 4 years now and I absolutely love it to death. If you have any questions, please feel free to send me an email, for reasons of maintaining a 4.0 I have had to sacrafice regular visits to this site, but I do check my email regularly. Good luck and congratulations on your purchase.
