I love my 2006 GS450h, but the seat is just a tad too high. Most of the time the top of my head is touching the ceiling. I can lower the back rest, but this is far from a comfortable driving position.
I had a look at the rail mounting brackets & thought that I might be able to get a metal fabricator to make a pair for the rear of the seat that are approx 1" lower. This would mean that the rails wouldn't be level from front to back as they would be at a very slight angle as a result of the height reduction of the anchoring brackets.
Am I daft?
