The only modifications are very minor- boring out the
centerbore 1mm and the bolt holes 1mm as well. That's not
a big deal at all. I plan on getting a spare set in the
near future to prevent any problems w/ rotor replacement
in the future.

As for the rotors themselves, they are a stock R129 part
and w/ M-B's rep on parts, they will be stocked probably for
longer than either of us will own our 200s.

If you want an alternative, call up Keith Anderson and get his
kit- it uses stock euro A8 rotors and the modifications are done
to the hubs. It's about $1600 give or take, all inclusive, lines,
pads and all.

Replacing the UFO rotors has caught my attention
recently since I'm still running original UFOs at

I believe BIRA is about to announce/release a UFO bolt
on kit that uses somekind of modified Mercedes rotor.

While upgrading is attractive to me (heck, I even
bought  17X8.5 Ronal R28s in anticipation of a brake
upgrade 2 yrs ago), I'm not sure I like the idea of
needing rotors that have to be modified to fit.

I wonder which is more likely to be available in 3-5
years? UFOs or modified Mercedes rotors?


Just finished building my diagnostic interface at a
cost of $12 plus a few hours of soldering.  Using the
free demo of vag-com, I was able to reset my airbag
light and discovered that I have an intermittant
intake air-temp sensor.  This is a vastly improved
tool over the led blinking thing on Scott's page but
takes alot more effort to build.
