I am actually looking into getting s2000 and have some problem wiht lack of leg room and have heard about the aftermarket seat bracket.
I would like to sit few inches lower than stock since my knee/leg rubs the bottom of the dash.

First question is is there a any aftermarket seat rails that fits the stock seat and lowers it? there seem to be alot of room under the seat. if there is one how much does it lower it?

second question is how mcuh does aftermarket seat with rail sit lower compared to stock.

and in ap1 seats is there a height adjustment?

thanks
