i have a '90 rx-7. i am putting my sparco rev in this weekend. i have the sparco competition brackets. my plan is to mount the brackets to the floor and use 3/8" aluminum on the understand of the car to increase strength. grade 8 bolts all around. the seat side mounts use 8mm x 1.25 bolts (not sure of length, probably 12mm to 20mm, anyone know?). my question: if you look at the floor board there are a couple of places that rise up (like where the orginal seat mounts would be - hope that makes sense). do i need to cut those out to mount the brackets? if someone has a pic of their's mounted that would be great. any other advice would be awesome!
thanks,
mike
