a hangin box mounted on a rollcage with dash remade to suit will work ,the boxs that fit to the floor don,t because the angles you have to set pedals at don,t work out with the sloping floor amd where your feet want to be relative to the pedals and where the seating postion is .
your other option is to resize all the claipers etc to match your chosen pedal box
the pressure i have stated is std caliper pressure you get on a std saxo and what ap racing will tell you is about correct for a good pedal feel
