start from part 1 and read through all the parts even the drifting set ups.

Slamming it makes it handle like crap because it practically eliminates suspension travel, and severly changes the suspension geometry. This car was designed to be the height that it came from the factory, a little drop may help, around 1", but 3" completely changes the way the suspension functions. If they were to redesign the upper and lower a arms, then they could potentially utilize that drop and have it not hinder performance.
Using cheap coilovers, regardless of ride height, also hinders handling. Sorry, but godspeed, d2, stance, ect are not quality. That is equivalent to taking all season touring tires to the drag strip. Technically they are tires, but not designed to be used in that way. Using quality coilovers, and dropping them lower than their efficiency range, essentially turns them to overpriced crap.
And about the tire situation- yes, a little stretch does help prevent sidewall flex and helps maximize tread patch. Putting a 245 on a 9" wheel is a good example of this. Stretching a 225 on a 10" wheel is not. It puts stress on the sidewall in ways it was not designed to, and decreases contact efficiency. Tires are designed to fit on specific size rims based on tread width. A 5'6" man weighing 400 lbs wouldn't go outside trying to fit in a 28" waist pair of pants- why would you expect your car to do something similar.

i belive i have good function and form... you can have the look you want and the performance you want... if done properly...
current set up 245 x4 17x9.5 work xd9s
tien circuit master RA's 2.5 inch drop all around
toe arms in the rear...
im one of the guys that went from hella flush (rice) to functional (nice)
teaser below of what i would say slammed functional

It basically boils down to geometry and the suspensions ability to keep as much tire on the ground through changes in direction and elevation.
When you slam the car you are reducing the ammount of room the suspension has to do its job. When you buy a cheaper coilover system that is
not able to do the job very well to begin with, and then give it a shorter distance to do the same job it just cannot keep the tire planted.
More expensive sets not only lower the car for looks/center of gravity but have the compression and rebound dampening ability to do the job as well as eliminating excessive body roll.
In most cases the stock suspension does a much better job at doing this because thats what it was designed to do.
This is just a very small part of what goes into it. But will give you a basic idea of why cheaper systems are not recomeneded for track use.

The stock suspension is actually very good. High quality, monotube construction... people ruin their cars handling by throwing on crap products with inferior design.

dropping it 3 inches hurts the roll center, and geometry as said above. About the only cars u will see riding around with good suspenion and slammed are the 240sx guys. they have tons of aftermarket support for suspenion, including some nice drop knuckle options.
as long as u keep the camber within reason, your car will be fine for street driving.
