Hit a concrete slab (FLAT SIDE) of about 12cm (5 inches) high at wot. Car did the most amazing tumbling and turns for another 20+ meters after the impact and died. The impact was so hard and loud that my father-in-law, who was sitting almost 75m from where it happened, thought it was a gun shot. Damage: Tire came of left front rim (some tire glue fixed this) and engine moved (took screws out, re-aligned the motor and tightened the screws again with some loctite)
