Nice thread of DIY. I guess I don't have the same issue with the seat since I'm just *that* much bigger and heavier than you (I'm a much larger person than Reedy if anyone wants to know) and I don't track my car. My weight keeps me planted, just the bolstering that causes some issues if anything... but once again, with my weight, not as much of a problem.
It's a pity the sliders didn't fit the plate properly and swapping seats is rather a pain. You'd think it'd be easy in, easy out... oh well. Nice one Reedy!
3 MPS - Rolling on Pirelli PZero Neros, sitting on Bilstein B12's, stock internals... still makes me smile with the Zoom Zoom.
