The T5 kart seat is a World Championship winning product, used by Lando Norris.
The T5 shape is now days predominantly used by younger or smaller drivers.
This model has a flat bottom and a more upright back position. The 63° back angle allows a powerful shoulder turn, which helps the very young racers.
With the T5 model, Tillett created the first ever “flat bottom” style seat. This innovation was eventually replicated by many other brands, as the iconic design feature gives a favourable performance advantage.
The T5 range offer four rigidities. T5VG is between the T5t and the softest rigidity T5VTi. See rigidity chart below for a better understanding.

This is important as a good fit is essential for the protection of the driver and the handling of the kart. If a driver is loose in a seat he will pull to steer, pulling himself out of the kart, making it bounce at the slightest provocation.
To assess whether or not the size of a seat that you have in your possession is correct, sit the driver should in the seat and feel the gap over the leg bone, the hip bone and down the length of the ribs, from top to bottom. This must be done with any rib protection in place, but the race suit is not so important unless it has integral padding. The rib protector when worn tight, should not move inwards as the driver sits back in the seat. Once sat back in the seat, it should be difficult to squeeze your fingers between the seat, your ribs, hip and leg bones. It’s important that all the points are evenly pressured and no one element is either loose or pinching. If one area feels loose, some firm foam stuck between driver and seat is acceptable. If it is pinching you need a different size.
To assess the size without having a seat in your vicinity, we find that denim Jeans waist size, weight and height are good indicators. Coupled with information about the chest circumference and rib protector type. An over thick rib protector can make two sizes difference and leave you with very loose hips, so this is to be avoided (i.e. buy a P1) or accounted for with a WT wide top T11 seat.
Now you have a good fitting seat it is important to fit it correctly, half the weight of the kart moved 5 mm out of position will alter the balance. Over the years the average seat position has been going back in the chassis. And the average is now three cm further back than it was in the late nineties.
