luckily my bmw seats fitted without much effort the only real problem I had was getting reverse,it takes some efford with big seats,mainly because the way the subframe design is,
anyway what i dont was sat the seats where they were supposed to go,but the holes didnt line up,so i drilled the holes out larger on the subframes ,then cut some metal plates with a grinder,to use as a washer,this means that my bolt wont go through the subframe ,in the event of a crash and me and the seat wont go through the windscreen,
my seats are not fitted ,the drivers one was fitted for ten mins ,but i removed it because its away with rallycinq for its MOT ,didnt want the mot dude to say anything about how legal my fixing of the seats is lol
