We consulted industry experts to determine the sizing of the LTR. It is made completely custom to our specifications so we could have made it any size or thickness. Turns out that thicker is not better when it comes to an LTR, exposed surface area is. Therefore we chose to design the tallest, widest, thinnest unit that would fit, without cutting up the car or rubbing anywhere. It is also a dual pass design. Multiple back to back dyno runs and pulls on the street have proven that there is no heat soak and the temperatures drop back down to cruise temperatures within 15 seconds.
