Dinan, a leader in BMW performance, is all about European performance. In fact, Euro upgrades are the only type of upgrades that Dinan creates. This helps them to be experts in the field, knowing European marques – quite literally – from the inside out. Dinan works with all types of vehicles, from the old to the brand new. They offer a variety of upgrades to customers. These upgrades may be in the form of hard aftermarket parts – such as exhaust, suspension, and intake systems – or they may be in the form of software upgrades – such as those that improve power output or remove the top speed governor.
