Since the 315 or 335 tires will not clear the inner wheel wells, we needed to make some more room. The suspension will also move differently than a solid axle (you get camber change now with the IRS), so that further defines the need to minitub the rear of the car. Since there is no kit available – we need to just cut out an inch of floorpan and add an inch to the inner wheel wells. Finally got to put the plasma cutter to its first test – is worth its weight on gold during this step. It is very easy to cut straight lines this way too.
Had to cut holes in the trunk floor so the upper control arms on the IRS would fit. Also hitting the pinion snubber and will hit the jounce bumper brackets, so those were cut off too. This all needs to be done so the car can have a lower stance and still sit at the correct “design” position as it was designed (and not just at some arbitrary control arm angle).
