The Vintage Sports-Car Club is to offer half-price entry fees to members under the age of 30 with immediate effect.
The discount had previously applied to members up to the age of 25.
The new arrangement means that under-30s would pay approximately £60 to enter a five-lap Scratch or Handicap Race and £83-120 for a long Trophy Race (depending on duration and venue).
Young membership to the club costs £37, while a junior membership for under-16s costs just £9.
PR manager Gillian Carr said: “The VSCC boasts young membership levels that are much higher than most vintage, classic and historic motoring clubs and has always welcomed a good number of young competitors to its events.”
