1. Vehicles running in Sport, Tuner and Max Categories must meet Safety Level 1 Standards.

A. Roll bars, cages, racing harnesses and other safety equipment may be added, and must meet manufacturers' guidelines for installation. It is highly recommended that they at least meet the minimum for Safety Level 2 or Safety Level 3 Standards.

B. Nothing in the rules prevents you from adding safety equipment; the minimum amount of modification to install safety equipment is allowed.

C. To facilitate safety, vehicles that have an added roll bar (4-points) may remove carpet, seats and trim (including convertible tops) behind the front seats. Vehicles that have an added roll cage (6-points) may remove carpet, seats and trim (including convertible tops) other than the dash.

2. Fuel cells may be used in cars with the following restrictions and allowances:

A. Any replacement fuel cell should be constructed and installed to racing standards. (E.g., FIA/SFI approval, fuel cell enclosure, bladder, and foam baffling.)

B. OE lines may be replaced in conjunction with a fuel cell provided they are shielded.

C. Any fuel lines—including gauge and vent lines—that pass into or through the driver/passenger compartment, shall be of steel tube or metal braided hoses or bulkheaded.

D. Drivers of cars with modified or replaced OE fuel lines or tanks must wear a suit, shoes, gloves and underwear as specified in SCCA Time Trials Safety Level 2 Standards.

E. Vehicles with modified or replaced OE fuel lines or tanks must have an on-board fire suppression (fire bottle or system) meeting SCCA Time Trials Safety Level 2 Standards.

F. Participants are cautioned that this is not an allowance to maximize fuel delivery by installing higher-performance parts than authorized by category rules. (E.g., installing an upgraded fuel pump if it's not otherwise allowed.)
