Raise your seat? im pretty sure if you measure the distance from ground to underbelly on both cars they will probably be pretty close. I guess my main question is why do you feel the need to be "higher". The CT is not a SUV its a hatchback hybrid, raising it you may lose some MPG(not sure if it will be significant)
Actually just looked it up, the 2013 accord has 5.8" ground clearance, the CT has 5.7", thats less than .125" (1/8")
