Well what do you know… one of my good cycling buddies turns out to be the GM of Dinan Mountain View. Dinan is one of the premier BMW tuners in the US. And since the Mini Cooper is owned and produced by BMW, Dinan has a host of upgrades for the Mini Cooper S.
I call up the GM and we talk about some options. I research the Dinan upgrades and there is nothing but great things about them. R&D, performance, quality, service are all top-notch. They’re not cheap but their upgrades are not hacks or experiments. Everything is designed to work together as an optimized and reliable system.
