Sorry, another question - on car prep this time. The Blue Book says that rollbar padding is recommended for all tubes within 150mm on the vehicle occupant's head. I was just wondering what people's practical experience was with scrutineers for SLR cages. Do they suggest/insist on rollbar padding and if so, fire retardant or FIA approved? From the photos I've seen, it looks like many competitors run with SLR cages and no padding. Thanks in advance, Ian.
