If the car is equipped with front side windows fixed, they must be made of transparent polycarbonate with a minimum thickness of 5 mm and have a small closable opening easily.
If the windscreen is glued, it should be possible to remove or break the glass front doors from the cockpit. Disassembly should be done without using tools.
The rear and side windows (behind the pilot), when transparent material must be approved or polycarbonate of at least 3 mm thick.
11.3. SAFETY NETS

When the car does not have side windows fixed front, it is mandatory to provide the following protections for the passenger side openings of the doors.
These protectors must prevent the passage of the hand or the arm and covering the opening over the entire height of the back and then to the center of the window of the steering wheel.

WHEELS AND TYRES
6.1.The wheels made partially or entirely from composite materials are prohibited.
With the exception of the liquids and gels puncture, the use of any device allowing the tire to maintain performance with a pressure equal to or lower than the atmospheric pressure is prohibited.
As of 01/01/06, wheel hubs should include a centering wheel by a shoulder, according to the principle used on production cars for new cars.
6.2. MEASURING WHEEL WIDTH
The wheel being mounted on the car and standing on the ground, the vehicle in race condition ,driver a board , the measurement of the wheel width is performed in any point of the circumference of the tire, except for the area in contact with the ground. When multiple tires are mounted as part of a complete wheel, it must comply with the maximum dimensions set for the group in which they are used.
6.3.Twin wheels are prohibited.
6.4. The tyres with nails , studded or teats or with chains are not allowed, except by decision of the Stewards when weather conditions are unfavorable and they compromise the smooth running of the race.
Are not considered pneumatic clamps or nipples, tires with the following characteristics:
- No gap between the two blocks measured perpendicular or parallel to the tread shall not exceed 15 mm.
In case of wear or tear of angles, measurement will be made at the base of the pavement. In the case of circular or oval stones, the measurement is taken to the tangent of the blocks.
- The tread depth must not exceed 15 mm.
These measures do not apply to a width of 30 mm and along each side of the tread, but the blocks must not exceed the balance of the tire sidewalls.
6.5 SPARE WHEEL Inall groups,the spare wheelis optionalexceptRally.However, if thecaris equipped,the number will belimited to two.
