Tillett B4 Carbon/GRP Race Car SeatThe B4 seat weighs 4. 9 kg and has been made to allow fitment into some of the narrowest vehicles around. Although light, it is still rigid due to its twin skin construction and it holds the driver in a reclined "formula style" racing position. This version of the seat is made from GRP with a layer of carbon fiber on the seating surface and the edges of the seat are kept on for added rigidity an aesthetics.

The B4 seat weighs 4.9 kg and has been made to allow fitment into some of the narrowest vehicles around. Although light, it is still rigid due to its twin skin construction and it holds the driver in a reclined "formula-style" racing position. This version of the seat is made from GRP with a layer of carbon fiber on the seating surface and the edges of the seat are kept on for added rigidity an aesthetics. The belt holes in the B4 allow a full 5/6-point racing harness to be used, which is strongly recommended on any reclined seat such as this. The B4 seat is not generally compatible with OEM 3-point belts since it is very hard to feed the lap belt through the lap belt holes and click it into the OEM receptacle, much less the danger of “submarining” due to lacking a center strap.Furthering it’s performance pedigree, the shoulder holes have been optimized to enable the use of a HANS device. The B4 comes complete with a Dinamica® suede covered headrest. Matching padded cushion and back panels are available at extra cost. However, the shape is so comfortable covering is unnecessary, making it ideal for open topped sports cars. The B4 has six M8 mounting points; two are up high at chest level and give more mounting options to the chassis. The four lower mounting points are for bracket options including:

  • The TB1 which point inwards under the seat and keep a small footprint. They allow adjustment of the seat angle and mount directly either to a flat floor, or the TR1 runner system
  • The TB4 is a 30 mm taller version of the TB1
  • The new TBFIAO8 fully machined billet aluminum brackets, which point outwards from the seat. If adjustment is required TR2 runners can be used under these brackets.

Very well designed mount but loosens over time
Style: Charging MagSafe Mount
Works amazing but over time the mount loosens up and the phone sags or rotates on its own. There is no way to tighten it more - only the part that connects to the Tesla display.

Great phone mount for Tesla.
Style: Charging MagSafe Mount
Firstly, I love that it is fastened to display via a turn knob. The previous product I had was attached by adhesive and in the summer it would fall off. Which is the reason I purchased this product. I also love the ability to adjust the arm so mount the phone whichever way you'd like.

I did not like it.
Style: Charging MagSafe Mount
I was hoping this would work well, but I’m not really impressed with it. The magnet is strong and definitely holds the phone well. It also charges the phone very well. It is also fairly easy to install. That’s about the end of the pluses. Using the rubber devices they give you to help run the charging cable is something to be desired. They have not done a good job of sticking. Either it comes completely off from the car, sticky part and all, or the sticky par stays attached to the car and the rubber cable holder comes off without the sticky or Velcro part. When it’s holding the phone, if there is any kind of vibration, it shakes the phone even more. It doesn’t seem to want to stay tight against the screen. I keep having to re-tighten it so it won’t fall off. I’m already looking for another phone holder.

Looks good, fits good, works good
Style: Charging MagSafe Mount
I LOVE it! I bought the one with the cord at first and then returned it for the one without the cord and I'm 100% in love with it. It looks good, the magnetic strength is awesome and I love the fact that it can swivel around too

Very slow, but good quality
Color: 2White
It works as expected, but my phone says that it is a slow charger even when plugged in my fast charger brick. False advertising. Really wish it charged a little faster
