Andy, thank You for your reply, My mechanic is considering either upgrading the UN1 gearbox currently on the car or switching to an Audi 6-speed gearbox with a 01E ratio. I've forwarded all your information to him while he decides... Thanks to everyone for your support, in any case... Regards Laurent

Laurent, je vais installer une boîte de vitesses manuelle 5 rapports pour R21 (kit Cris Cole complet avec première et deuxième vitesses longues, différentiel Quaife et arbre primaire monobloc). J'ai également une plaque d'adaptation pour SBF de GTD, un démarreur, un volant moteur pour SBF de 1,4 kg (50 oz), un embrayage et un système de changement de vitesses complet avec câbles adaptés à la GTD. Je suis au Texas, aux États-Unis. Les frais de port pour l'Europe seront importants. Où êtes-vous ?

Bonsoir Howard, je suis en France ! Cordialement, Laurent
