How To Modify Your Lexus IS300

Modding Your Lexus IS300

Today, we embark on a journey into the world of a car that dared to be different, a car born from a passion for everything motorsport-related.

Easter Eggs and the IS300’s Evolution

This car was no ordinary sedan; it was the evolution American automotive enthusiasts needed. The IS300 boasted a 3L straight-six engine, available in a 5-speed manual, producing 217 horsepower. It was a game-changer, breaking free from the mold of aging Nissans with mileage issues. Even the 2000 station wagon model became a sensation in 2013, proving that it was ahead of its time.

Modifying the IS300: Key Upgrades

Now, let’s get into the nitty-gritty of modifying the Lexus IS300. Here are some key modifications to enhance its driving experience:

Suspension Upgrades: Consider coilovers from Fortune Auto for track racing or BC Racing if you’re on the streets. The BR Series or 500 series coilovers will be perfect for all entry applications.

Wheel and Tire Setup: Opt for 18×8.5 +35 wheels with 215/40 or 224/35 tires for a saucy look. Choose lightweight designs like windowed five spokes or a simple six-spoke to avoid the car looking bulky.

Exhaust System: The Greddy Supreme Exhaust is a top-notch choice – it sounds great, adds 10 horsepower, and weighs just 33 pounds with a 3” output for that perfect rumble.

Resisting the Temptation of Engine Swaps

Resist the urge to throw a 2JZ-GTE into your IS300; it’s not a one-size-fits-all scenario. Instead, focus on a few key mods to dial in the driving experience, keeping in mind the car’s roots in light, nimble luxury.

Finding Balance: Enjoying the IS300 for What It Is

The IS300 is not a car meant for massive power upgrades. Embrace its identity as a four-door luxury, fun car with a manual transmission. Avoid the trap of overbuilding; enjoy the unique experience the IS300 offers.

Personalizing Your IS300 Experience

To modify your Lexus IS300 effectively, start with a clean example. Address rust issues, restore the interior, and delve into watch collecting inspired by the Chronometer display. Tighten the suspension with BC Racing or Fortune Auto coilovers from MartiniWorks, upgrade tires and wheels, and attend some autocross or drift events for the full experience.


In conclusion, modifying the Lexus IS300 is about appreciating its unique character. Don’t chase excessive power; instead, focus on enhancing the driving experience with thoughtful upgrades.

I like to slappa da wheel. Also, I drive a 2020 Toyota Supra. No, its not manual. The engine is from BMW.
