You definatly lost power. This is because of the added unsprung mass of the heavier wheels, and also the extra friction from the wider tires. The wider tires will help you get better traction, but they will slow you down at the higher speeds.

Does this help?

Well, the other solution is to get more power out of the engine to make up for the added weight and friction. The old american saying "If you have too much power, you need wider tires. If your tires are too wide, you need more power!"

Could you post some pictures of the M3?
