Welcome!
There are a lot of options for mods, and most people seem to mod the FiST at least a little.
The first mod to do is a RMM (rear motor mount). The stock one is just too soft for anything but slow, easy shifting. You may already have one on it. A shift kit will shorten the throws, and make it feel more positive.
A tune will give it more push. You can go anywhere from a mild tune with no other mods to a big turbo that'll give you 300+ hp, if you want. I have an intercooler with an opened intake and a custom tune from a good tuner. It's quick enough for me, but some folks want more, and it's possible. You'd need some sticky tires to put the power down, though. I get a lot of spin with the stock tires.
I have mostly mountune parts. They're pretty and work very well. There are lots of other choices, though. Whoosh carries all kinds of goodies for this car.
