I have the Sparco Torinos in my 91, and that seem a little bit higher than the stock seats, they also dont have that nice high thigh, low butt curve as the factory seats, all though the side to side support is better. They do feel heavier than the stocks when i put them in. The seat rails were ones that i welded up for myself, because i wanted them to be as low profile as possible, but it still ended up a little higher than stock.
I am getting rid of the seats and will be moving to either the roadster or the fighter next.
Oh yeah, the tourinos handles to flip the seat forward interfere with the seat being able to move all they way back (but i'm not that tall so it doesnt matter to me)
