Those look awesome, Jim
What pads are you going to mate them with? 
Enjoy your upgrade!

I got the Brembo rotors at Brakeworld. They are from Brembo Italy and are Nickel plated. I will be using Rotex pads. Purchased new sensors, rotor mounting screws, Anti squeek lube, and new mounting bolts (MBZ recommends changing the 4 Hexhead mounting bolts when changing rotors) All parts at my dealer for $40.00
Anyone know the torque value on the caliper mounting bolts?

My, my, do those rotors look nice! I am sure they will improve the braking as well as the appearance.
They do look good though. I hope you have some rims that will show those rotors!

The vented and drilled rotors are better at eliminating heat than the solid rotors. However, they are also very prone to cracking around the holes.

When you drill your rotors and do not increase the size of the rotors you are actually decreasing the contact area of the brake pad which can cause decreased stopping ability on the street. If you run your car very hard, yes, the slotted and drilled rotors may be for you but for the average driver they will see little if any benefit.
You are comparing cars that run four piston Brembo's calipers and rotors that are much larger and much thicker than a stock E430's too. It's comparing apples to oranges.
Yes, on the track. The slottted and cast in hole, not drilled, may give you better braking than solid rotors due to the theory that the rotor has more ability for heat dissipation caused by repeated hard braking. Many discount this theory because new brake pads do not have an issue with gas build-up between the pad and the rotor. Older brake pad technology had not solved this issue so back in the day it was necessary to drill your rotors to remove the gasses but now it's not really necessary.
With the cooling theory in mind, if you drive like a maniac and make stops from very high speeds, then by all means, go for the "drilled" rotors. Otherwise, you are wasting your money unless you have some rims that will show-off the rotors because they do have that "bling" appeal. Cast hole rotors, as a rule, do show better braking in wet weather on street cars. However, slotted rotors are really the way to go in all conditions.
Make sure you check for cracking between the holes. Those holes are stress risers and cracking can cause the rotor to fail. It's not pretty when you have one that fails.
