I cant get in the back of mine unfortunatly but i never really have more than 2 people in the car. I ended up taking the motor assembly off because it was making the seat sit too high for me (im 6'3")! I tried the tippy mechanism off the original seats too but just didnt work out! the seats are now bolted through the original front fixings and then welded legs on the back of the seats and bolted through the floor, they sit perfect now.My seats are from a BMW Z3 and fit a treat! Had to make up some brackets to make them fit though.
damn you got there before me, can you get in the back of yours?
Its passed 2 Mots like this so i think its ok!
