Hallo Peter,
Bij deze de sectie technisch reglement van de ARC. Volledig reglement is na te lezen op de website (zonder webfilter dan)
Indien je buiten M3000 valt, kom je in M Plus terecht, waar ongeveer alle alfa met alle alfa motor mag deelnemen.
Mijn inschatting is dat je zo kan deelnemen, alleen de achterspoiler en voorspoiler is niet toegestaan, daar zal een standaard door Alfa geleverd exemplaar op moeten om niet aan de regels mbt silhouet voorbij te gaan. Maar neem gerust contact op met het ARC bestuur! Die kunnen alles toelichten en zeer bereid te helpen.
Groet, Pieter
