The use of cambered front wheels does not void in any way the rule regarding the minimum diameter, nor the rule regarding the contact surface with the track or the tech block.
Front wheel diameter for cambered front wheels will be measured at the largest present diameter, which has to be respecting rule 1.08.
Rear wheels are handout Scaleauto ProComp wheels, trued to Ø27.3 mm – Ø27.4 mm, 13 mm wide, Ø20 mm inside. Tyre dressing of any kind is not allowed during the official training or during the race. The hand out race tyres may be only be cleaned by using the tape supplied by the OEPS organization.

All 4 wheels of the car must be fitted with 3-dimensional wheel inserts, resembling the wheels of the real 1:1 car, during the entire race duration
