Why this upgrade?

The Toyota GR Supra is already a capable sports car, but the OEM chassis tuning can sometimes make it feel softer and less responsive than its potential allows. The HKS Hipermax R fully corrects this – without completely sacrificing comfort. Perfect for those who want to use their Supra on the track but also enjoy weekend drives or sharp corners on public roads.

Give your Supra the chassis that matches its motoring potential – with HKS Hipermax R.
