Update Resistors:
The resistor surfaces heat up fairly quick. The 1st 5 mins saw a rise from 87F to ~350F. Over the next 20mins it rose to ~500F and stablized @ that temperature. The ambient temperature around the resistor @ a distance of ~4in was ~ 260F. So I would definately attach the resistors to some part of the frame/body point to conduct some of this thermal energy. More so, the primary benefit would be to prevent the resistor from coming into contact with soft materials like plastics and wire insulation in the vicinty of the resistor. Wiring is the most immediate concern as there is a potential fire hazard if the bare copper becomes exposed as a result of a melted casing due to prolonged contact with the resistor surface.
One other curious thing, I havent installed these resistors yet and so far my 2003 330i (facelifted sedan) is not complaining about the change in load....
Leds:
As someone mentioned earlier you have to trim the SMT 194s down a bit. I trimmed them down quite a bit more than need to fit into the housing but they are now about the same size as the original incadescents. This is a fairly trivial task, just be careful not to snip the wires as you remove the casing material. Here are some pics for the curious:
