ALL cars racing this year must have the front part of the rear wheel arch in place, if removed they must be made of steel. No plastic or aluminium.
Outer sills maybe replaced with Tin but part of the original sill with the drop-down lip must still be in place, the guts in between inner and outer sill may be removed this is mainly on a Tigra ‘B’ where there is possibly 30-40kg of weight.
Cars that haven’t got inner sills must have them replaced by the 1st of January 2020.
The ‘A’ pillar can only be cut a maximum of roughly 1” above the top wing iron & roughly 1” below the bottom door iron and the rest must stay in. If the ‘A’ pillar is removed this must be back in place for the 1st January 2020.
Rules for 2020, any car that hasn’t raced before this date must have the original rear-wheel arches in from the centre line forward, the boot floor maybe cut out, the reason for this is where we are making them put the floor in then remove a 3rd of it for the fuel tank.
New cars that come out from the 1st January 2020 and not to these rules will not be able to replace the inner sills, rear-wheel arches and ‘A’ pillars. They will not be allowed to race the car at any of the associated tracks.
