Tillett's T11 is wildly popular among racing teams across the USA and world. The T11 features a flat bottom which allows the seat to be mounted lower in the chassis. This enables taller drivers to lower their center of gravity within the kart. The T11 features a 58 degree back angle, which lowers the driver's head and shoulders relative to the T8.
The T8 seat is the best selling seat in Tillet's Range. The T8 seat features a more upright 63 degree angle which moves the driver's shoulders closer to the steering wheel, and is a fantastic option for drivers with shorter arms. The T8 seat is also fantastic for taller and larger drivers who find themselves sliding out of the T11 seat. The T8 seat will normally fit a driver "deeper" in the hips and ribcage area.
Available in both handmade and RTM style seats.
Soft flex, reduced seat stiffness which in turn reduces the overall chassis stiffness.
Very Soft, reduces seat stiffness even further than the "T" stiffness.
Supersoft, extremely soft!! This style seat is often special order only and may have long lead times.
Mounting a seat is one of those things that can be very intimidating at first, but with time, becomes a very easy process. The main objective of mounting your go kart seat is to place your bodyweight in the correct position within the kart. It is common for many Sr. drivers' bodyweight to account for over 50% of the vehicle's total weight. For this reason, placing the kart seat, and subsequently the driver's bodyweight improperly can cause a wide range of handling issues.
Your main goal is to place the seat properly within the kart chassis without any twist, compression, or strech as the hardware for the seat is tightened!
Vertical position relative to the bottom rails is critical to the grip level of the go kart. Mounting the seat high in the chassis increases the leverage the driver's bodyweight will act upon the chassis with. This can be very beneficial in low grip circumstances, or in the rain. As grip increases, it is often very undesirable to have the seat mounted high in the chassis. This will result in an "overgripped" situation, resulting in "hopping" or "bicycling".
This is the seat's position in the go kart relative to the front hoop. Moving the seat back in the go kart puts more of the driver's bodyweight onto the rear axle and off the front. Moving the seat foward has the opposite effect.
In many seat installations we often see the right front corner of the kart seat mounted further from the front hoop than the left front. This helps to position the driver's upper body, shoulders, and head slightly left of the chassis centerline. By doing so, the driver's bodyweight can counterbalance the weight of the engine sitting on the right side of the driver's body. The degree of twist can vary, but it's often common to see the right edge placed 1cm further from the front rails than the left.
*If you need to create a spacer with an angle to it, try using a 1.5" Ø nylon round bar. I buy these from McMaster Carr. Grab your miter saw and set the blade to the apropriate angle. Cut the angle first before you part off your spacer with a square 90 degree cut. USE CAUTION AND GO SLOW DURING YOUR CUT. This material is dense and will grab if you try to cut too fast. Once your angle is perfect, return the blade to 90 degrees and cut the spacer to the apropriate length. Next, put an 8mm hole through the center and you're ready to install it!
