After some studying of the PGT rules and FIA Gr N4 I realized that we are about 75~80 % identical to that class. Some wording is the same (was it copied from there?)
any how, what is the general opinion to close the gap to favor Gr N over PGT ?
biggest impacts: 1350 kg minimum weight or FIA homologations weight (homologated by manufacturer) or manufacturer curb wight (current PGT rule)
33 mm turbo restrictor
transmission: homologated gear ratios are allowed
other than this is amlost the same, a bit more details on parts in the FIA regulations and allowance on homologated parts by the manufacturer(not too many)
