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.
