GT-X Class Rules
(2024 Edition)


Vehicles in GT-X are held to the standards found in Section 1 in addition to the
allowances below. All Super Sport vehicles must meet the GTA Safety Mins safety level 3 standards found in GTA Safety Mins. GT-X Class vehicles are required to pass a mandatory safety inspection. If the GTA officials do not feel your car is safe to race you will not be allowed to compete. For guidance please refer to the safety regulations for race vehicles as described in Safety Level 3 of the GTA Safety Minimum. This means proper fire-retardant driver’s attire, onboard fire extinguisher or fire system, a minimum legal 6-point cage, 5- or 6-point driver’s restraint, etc. It is up to you to make sure your vehicle complies. If you have any questions, please ask.

Any questionable modifications not specifically covered within the class and overall rules must be submitted for clarification and allowed by GTA Staff. If you are unsure if your vehicle meets the regulation requirements, it is your responsibility to clarify any/all areas or points prior to an event.
