HKS Hipermax R Coilover Kit – Toyota GR Supra A90 (2019+)

80310-AT003 | Top-tier track and street coilovers for the serious driver

Transform the handling of your Toyota GR Supra A90 with the HKS Hipermax R Coilover Kit – the flagship among JDM coilover kits. Developed by HKS Japan with track use in mind, yet surprisingly comfortable on the street thanks to advanced damper technology.

The Hipermax R series is the spiritual successor to the legendary HKS Hipermax IV GT and SP systems, but has been further refined with new damping characteristics, lightweight materials, and motorsport-derived technologies. This kit offers maximum grip, feedback, control, and durability, whether you're carving through winding mountain roads or pushing the limits on the track.

Key Features:

✅ Top-tier performance coilover with motorsport DNA
✅ 30-way adjustable damping (bump & rebound) for optimal tuning
✅ Fully height adjustable without losing spring pre-load
✅ Monotube gas dampers – direct response and consistent performance
✅ Specifically developed for the Toyota Supra A90 DB42
✅ Includes aluminum camber plates (front) for sharper steering characteristics
✅ HKS's unique "PNE Coating" for long-lasting corrosion protection

Why choose HKS Hipermax R?

The Hipermax R is designed for the advanced driver who wants to get the most out of their GR Supra. Compared to street-oriented systems like Hipermax S or Öhlins Road & Track, this kit offers more grip, more direct steering, and improved feedback, without completely sacrificing comfort. Ideal for track days, canyon drives, or Autobahn use.

The 30-way damping is finely adjustable, allowing you to find the exact balance between grip and comfort. Thanks to the monotube design, damping remains consistent, even during intensive use.

Why this upgrade?

The Toyota GR Supra is already a capable sports car, but its OEM suspension setup is sometimes perceived as 'softer' and less sharp than its potential allows. The HKS Hipermax R completely rectifies this – without fully sacrificing comfort. Perfect for those who want to use their Supra on the track but also enjoy weekend drives or carving corners on public roads.

Give your Supra the chassis that matches its engine potential – with HKS Hipermax R.
100% performance. 100% JDM. 100% HKS.
