Quick pic of mine don't get me wrong it's nice to have seats but I never used them so they belong to the attic now! It's noisy but you get used to it, it depends what your building your car for, the 96/97 seats weigh naff all compared to the 98/99's I found. You can unbalance the rear but coilovers and a full tank of petrol should compensate for that, these cars beat bigger things due to their weight it just makes sense to make them even lighter but it's each to their own.
