Successfully installed 1 1/4" square tubing under my front seat rails today. Also moved seats back 3/4". For me with my long legs, I can now get the driver's seat perfectly adjusted with the right amount of front thigh support.
Also, my long trip MPG is most likely impossible if there's any...
Good news. I just drove 100 miles on relatively flat terrain. Dash said that I got 30.5 MPG. Average speed somewhere between 65-72 mph. Car has 300 miles on it, so engine very fresh. The throttle is really sensitive at tip-in, so I had to be very careful with that.
Really like this car, great...
