Opened the box up and was immediately impressed with how well everything was put together. Clear and concise instructions, every component you could ask for and so easy to initially set up. The DriftBox can measure acceleration increments, top speed, lap times and drift angles. It also has full data logging facilities too so I'll be pratting around with that at the next trackday. I have opted for the additional GPS antennae to make sure that the information that I get is as accurate as possible.
You can input points of interest into the DB via its SD card (also provided) so if you're approaching a 'safety' camera, the DB will sound an audible alarm and flash the correct speed too. Damed clever stuff for the money and I'll keep this post updated with my findings and reports.
