What are the best aftermarket modifications for a Toyota Corolla?

I recently purchased a Toyota Corolla and I'm looking to personalize and upgrade my car. What are the top modifications that I should consider?

From my experience, the first modification you should consider is upgrading your suspension. A good set of shocks and springs can greatly improve the handling and cornering of your Corolla.

In addition to suspension upgrades, you should also consider adding a cold air intake and an exhaust system. These will not only improve the performance of your car, but also give it a more aggressive exhaust note.

For a more aesthetic improvement, you could upgrade your wheels and tires. Not only will they look better, but they can also improve the grip and handling of your Corolla.
