OK so once again I'm going off plan and mounting the seat upper anchor points on the rear suspension towers. Obviously I'll be making a modified rear tube to accommodate this change. This position was only possible as a by-product of lowering the floor 40mm and using modified MX-5 seat base and home made runners/brackets.
Any comments on IVA compliance strength wise. Obviously it's only tacked in at the moment. I was thinking maybe I should put in some bracing from the inner anchor points down to the upper-back of the diff cage.
Sits nicely over the shoulder without touching the headrest.
