How Super GT Balances Heavy Success Penalties at the Pit Stop

Nominal Weight Versus Physical Caps

In Super GT, championship leaders face performance equalizers that scale directly with accumulated points. In the GT300 category, the baseline penalty assigns two kilograms of nominal ballast for every Drivers Championship point scored, reaching up to a maximum threshold of 100 kilograms. While regulations previously adjusted this figure to three kilograms per point during the 2020 season before returning to the two-kilogram baseline, carrying extreme physical ballast created serious vehicle dynamics and safety worries among competitors.

Translating Penalty Weight into Pit Time

To mitigate structural and safety risks while preserving competitive balance, modern Super GT success ballast rules enforce a strict physical cap of 50 kilograms onboard the car, aligning GT300 with GT500 standards. Any nominal penalty that surpasses this 50-kilogram threshold is not loaded into the chassis; instead, it is converted into a pit lane handicap via a mandatory Success refuelling restrictor. Fitted beneath the shut-off valve on the fuel rig, this component restricts flow rates and extends the time required to complete a pit stop, balancing car performance through strategy delays rather than excessive onboard mass.

Championship Climax Adjustments

The championship battle shifts dynamically as the season draws to a close. For the penultimate event of the calendar, the handicap drops to 1.5 kilograms per point scored, and for the eighth and final round, the ballast resets completely to zero for every entry that participated in all preceding races. This structure ensures that title contenders who carried pit-time handicaps and weight throughout mid-season campaigns can contest the final round without artificial mechanical penalties.
