Toyota A90 Supra Horn Upgrade (2019–2025)

2 min read

Upgrade your Toyota A90 Supra horn with a dual freeway loud horn kit. Using both high-pitch stock sound combine with deeper, aggressive tone. Professional installation recommended - and available in Melbourne.

Why the Stock Toyota Supra Horn Needs an Upgrade

If you own a Toyota A90 Supra (2019–2025), you know how much attention the car gets on the road. Unfortunately, the factory horn does not sound right and live up to the A90 Supra character. The stock horn is high-pitched, weak, and sounds like a 'a clown' . Many Supra owners avoid using it altogether because it feels out of place in such a performance car. Thats why at Sequential Racing, we've tested and found a solution to combine your stock ones with a low sound one. Therefore easily reverting back to stock in the future if needed. (We highly doubt it)

Benefits of a Loud Dual Horn Upgrade

Upgrading your Supra’s horn isn’t just about sound — it’s about safety, confidence, and character.

  • Louder for safety: More noticeable in heavy traffic and emergencies

  • Deeper tone: Combines high pitch with low tone to make a deeper tone. 

  • Dual-tone setup: Clearer and fuller sound compared to OEM

  • Peace of mind: You won’t hesitate to use your horn when you need it most

  • Dont sound like a clown

With the release of the GR Supra in 2020, we witnessed the culmination of a two-decade-long anticipation. The GR Supra also referred to as the MK5, underwent a remarkable transformation, blending its iconic JDM heritage with contemporary design elements, including contributions from the renowned BMW Z4 platform. While some may perceive this collaboration as a departure from tradition, it's undeniably a testament to the enduring allure of the Supra lineage, echoing the legendary 2JZ engine resonating through to the B58.

Behind the wheel of the GR Supra becomes the focal point of admiration, drawing fellow enthusiasts and eliciting spontaneous snapshots from passing people. My own journey into automotive culture was shaped by the vibrant scene of the 90s, particularly growing up in Melbourne, where car salons and cultural exhibitions brought JDM customization to life, from slammed suspensions, to under glow lights, supercharged turbos adorning from the streets to showroom exhibition floors.

Amidst the rapid evolution of the Australian automotive landscape, I recognized an opportunity to cultivate the car community around the modification and enhancement of the GR Supra. This endeavor is dedicated to providing a specialized platform centralised enabling high quality products sourced into Australia for car enthusiasts like myself on the limitations of the GR Supra (Unlike US and Japan).

While the Australian market for car modifications may be comparatively modest in scale compared to regions like Asia, USA, or Japan, our aspiration is to create this community from an inclusive space where like-minded individuals can access products, meet, share insights from a the collective experience of automotive enthusiasts across the nation- and hopefully one day globally.

Join Sequential Racing Australia as we embark on this journey, celebrating the legacy of the supra and championing the spirit within Australia's dynamic car modification community forging connections through our shared passion for automotive culture.

Thank You
From All of Sequential Racing Team
