Thank you Gentleman Mike…
May be you could consider the "Deux Tours d'Horloge" by Eric Van de Vyver, a real 24 hours race. Dates should be 6,7 and 8 of November, Circuit Paul Ricard also said Le Castellet.
VdeV and HVM racing joined their forces to have this race back on the calendar. Fingers crossed, its always been a lot of fun.
Contacts are VdeV Sports and/or HVM.
Cars: GT/ Tourisme up to 1990, Sport Proto up to '76 and Sports 2000 to '84. Slick tires not allowed. Others can be considered I guess.
