Retro Car Museum

Upgrading braking using either bespoke parts, parts produced by the vehicle's manufacturer, from later versions of the same model or later models that may be compatible with minor modification, is an effective way of improving safety. Popular examples include drum brake to disc brake conversions, or adding a vacuum servo to cars with front disc brakes that didn't originally have one.
Some classic cars owners are reluctant to retrofit seat belts for the loss of originality this modification implies. There have also been instances of cars losing points at shows for being retrofitted with seat belts.
Despite these concerns, classic cars are involved in relatively very few accidents.
