About a week ago we were with 4 adults in an RX8. One might notice nothing big. Logically the car is now a bit heavy etc. But at not even 50 km/h we came to a small threshold which was hardly visible whereby the ground of the RX8 banged loudly against the asphalt…. What could that be???? Is the chassis simply not designed for such a weight or the car just basically crappy????
