if anything, i would think that lowering your car closer to the ground would reduce drag. i mean, by having less air running along the bottom of the car, you are reducing the amount of total surface area that comes in contact with air molecules. less surface area=less total drag. it's simple physics. on the other hand, having all that ICE in your trunk would probably slow you down. but that's not really a BAD thing....too much stereo, that is.......
Well this extra friction of wider tires will cost you fuel economy and top speed, but on positive side you will get more traction which could only help your acceleration time and not slow you down during acceleration at all.
As per lowering your car and making it slower, WELLL YEAH... ON SHOPPING MALL PARKING LOTS because of all the speed bumps. But if that is bothering you... why don't you start racing else where?

Yeah, that's why you don't see drag cars running 18" rims. For flat out acceleration, alittle sidewall flex is good, and you get that with smaller rims. Plus, smaller rims typically = lighter weight which in turn = less rotating mass that your car has to get turning. It's all in the physics baby!!!!!!
another way lowering can make you slower is if you haveta wait for a cop to pull you over when he thinks the car's weighted down with a shipment of drugs, as happened to my friend (in the cop's defense, this probably only happened to him since my friend was driving a minivan lowered to have a handicap ramp)
lowering wont make u slower unless u have a huge spoiler/wing or air scoops in front...it only reduces drag and adds a tid bit of more down force..dont listen to insane people...its not smart...lowering basically makes ur car look nicer, cornering is nicer, reduces air resistence and makes u hit speed bumps if u lower it that far...
