I am 6'2" 200 and I cannot fit in my s13 with my helmet on (this is a huge problem)...What combination of seat/rails will get me the lowest...I need about 2 inches...I was looking at the Bride Zeta type-l, sparco pro2000, or the sparco evo....any help is appreciated!!!!

 

A bucket and some side mount rails (bride makes some, so do other companies just cant think of them off the top of my head) should get you pretty low, just stay away from bottom mounting a seat as this will, in most cases, raise the seat up higher than stock position. If all else fails you could always bolt the seat to the floor

 

Is the floor strong enough to support that? I mean you could reinforce it but just the sheet metal wouldn't hold I don't think...at least not to any race specs.
