Hi,

I'm obviously new here, but had a quick question. My seat is too high in my Corolla (ITA) and I need to lower it so that my head does not smack against the rollcage. I cannot lower it as much as I would like as the catalytic converter 'bulge' in the floorpan will not allow me to. Is it within the rules to cut out this bulge and weld in some sheet metal to allow the seat to be installed lower? Obviously, there is no performance gain by doing this, just the increased chance of surviving a rollover. Any input is appreciatted.

Thanks
