Which is the best modification for the Toyota GR86?

I recently bought a Toyota GR86 and I'm looking to make some modifications to improve its performance. What is the best modification I can make to my car?

It really depends on what you're looking for. If you want to improve acceleration and horsepower, you could go for a cold air intake or an exhaust system. If you want better handling and grip, a set of upgraded tires and adjustable suspension would be the way to go.

I personally would recommend investing in a good tune and ECU remap. This will optimize your engine's performance and give you a noticeable increase in horsepower and torque. It's a bit pricier than other modifications, but it's worth it in my opinion.

One of my favorite modifications for the GR86 is a limited slip differential. It improves traction and makes cornering smoother and more controlled. It's also a great addition if you plan on taking your car to the track.
