The circuit is really great, the only problem is that every car is different so it's impossible to set up a fair competition. I've been there with my colleagues in May and engine in car nr.1 was just stopping on the straight line, car nr. was not stopping but even without stopping it was slower than nr.1, car nr.7 was 4 seconds faster on lap than others... Get this track and cars from mobi and you have perfect go-kart facility, unfortunately how it is now only 3/5
