How much time can a high performance electric kart last?

Fittting the seat is a delicate operation: if it is fitted under tension, the distribution of the weight of the chassis without a driver on board changes. To check whether the seat supports are under tension, place the kart on four scales, one per wheel, checking before and after fitting the seat if the values change. Apart from changing the weight distribution, supports under tension can lead to the formation of cracks, shortening the life-cycle of the body in the long run.
