Registrazione della sospensione
posteriore
La registrazione della sospensione
posteriore dovrebbe essere effettuata in
base alla sensazione che il guidatore ha
di una corsa effettiva e alle condizioni
del circuito.
La registrazione della sospensione poste-
riore comprende i seguenti due fattori:
1. Registrazione del precarico della
molla
9Cambiare la lunghezza registra-
ta della molla.
9Cambiare la molla.
2. Registrazione della forza di smor-
zamento
9Cambiare lo smorzamento
dell’estensione.
