Basically I agree with Greg when it comes to the "street car." If you're just driving to the store and around town,other than looks, it's more of a PITA. My 87 is lowered and I really have to watch it.
Of 1/4 mile, you're generally better off NOT having it lowered.
One advantage of lowering, although not a big one for our cars, is better mileage due to redused drag
For a road course/Autocross car, it will definately help, but again, you have to know what you're doing.
The one Rachelle mentioned might look stock, but what suspension pieces does it have underneath?
As a rule, any time you lower the CG, you're going to enhance "g" performance.
There's a lot more to it than that, but bottom line, do what you like
Personally, I'd lower it, but I drive (corner) hard and like the looks
Not much of a 1/4 miler
