i dont THINK they are, but realistically mate, i had them in my old drifter RX7 and i took them out... They suck for street use, pain in the ass to get into and out of, and if you use them properly, your range of movement in the car is highly limited, you cant really move to check blindspots it just annoys the crap outa you. Id say if you were that keen on them, use them for track days etc and take em out again
