Change of Direction from Fixed Axle to IRS



What follows is the result of a "rush of blood to the head" following an engineer's talk at a VCBG meeting on the merits of IRS versus the std fixed rear axle. So out came Mr Angle Grinder and away went the entire rear section of the frame. From that point on, I was pretty much in uncharted waters as far as the frame design for the IRS, although I did have a set of Mazda MX5 IRS drawings showing the suspension pickup points. I followed these to the letter. My frame is +100 wide on the "book" and works well with the standard MX5 rear.
