What are some important factors to consider when buying aftermarket parts for a Toyota GR86?

I am looking to upgrade my Toyota GR86 with some aftermarket parts, but I am not sure where to start. What are some important factors I should consider when making a purchase?

First and foremost, make sure the parts are compatible with your specific GR86 model. Double check the year and trim of your car before making a purchase.

Research the brand and read reviews from other Toyota GR86 owners. You want to make sure the parts are high-quality and reliable.

Consider your budget and prioritize which parts are most important for your car. It's easy to go overboard when upgrading, so set a budget and stick to it.

Don't forget about installation costs. Some parts may require professional installation, so factor that into your budget.
