Blow off valves and dump valves.
When the throttle is closed (when you lift off the accelerator) in a turbo driven engine there is a build up of pressure as forced air is still coming from the turbo. Lifting off the throttle is a lot like putting a plug in the sink – the flow through is stopped and water would just build up and overflow the sink.

Some rally style alloy wheels are lighter – (less weight = more speed) and also are designed to increase the cooling of the brake disks.
Some designs hold up better to being curbed than others and some break very easily when hitting a pothole or curb at speed.
Always go for the best quality alloy wheel that you can afford and read the reports and reviews. If you do go for a different overall size you must get the suspension and tracking realigned to avoid uneven wear under acceleration.
