I'm sure Brembo makes a brake upgrade. You would likely have to buy 17" or 18" wheels depending on the size of your upgraded rotor/caliper package. Brembo does not sell directly to the public. Actually, we have talked with Brembo about advertising/distributorship. If you are in a major hurry for the brakes the usual suspects can supply the Brembo stuff. (bekkers, Renntech, etc)

Suspension bits for the W140 are a bit less common but they do exist. You can always buy from a tuner (cost no object method) or buy basically the same stuff from Bilstein and Eibach/H&R. Eibach has a "Pro-kit" set of springs for your year/model for $325 US. H&R makes sets for both self-leveling and non-self leveling for your car that drops the front and rear by 1.3" for $300 US. Add the price of Bilstein "Sport" shocks and install + alignment and you should be done. Renntech makes a kit for about $1,500 without labor. We will keep you posted on any developments. If there is anything else you need, feel free to ask.

Hope this helps...Lee
