now now, let's not get all rice about your corolla. Body kits are over rated with the exception of a fat lip, which I can give you if you step on my toes.
As you are on your P it will be some time before you can "go fast". So... get some good wheels, I wouldn't go bigger than a 15" as it will compromise your ability to turn corners fast and hard. Get some lowered springs, which will lower and stiffen your ride.... and don't cut the ones you'ce got. Get a front strut brace to reduce "chassis flexing" in the front.
That alone will enable you to go around corners fast.
From here make your car comfortable with stereo, fix any damage, or anything that is cosmetically wrong.
Now for the next 3 years save you money, look after your car with regular service and maintainence, don't smoke weed and by the time your on your opens you can do what you want to the car you have or like me, buy a ke20!
PEACE!
