S1 Elise seat runners – special, please read

A pair of S1 seat runners.
Driver’s side (obvs the adjustable one) has been adapted to lean the seat back five or so degrees.
I’m 6’ 3”, so I had my local garage adapt the tabs at the rear to lower the seat to the max. This in turn tilts the backrest slightly. Reduced the height of the top of my head by about two inches.
I used them in a 1998 S1 and my 2000 Sport 160. Now sold, so no longer required. You can see the difference if you look at the top of the headrests in the last photo.
I know there’s a safety aspect to changing the seat mounting bracket. If you don’t trust the engineering, don’t buy them. It never bothered me.
Will only sell as a pair. The passenger one is standard.
