S2 Lotus Sport Seats into an S1?

Pretty much as per subject… is there much of a difference between the S1 Exige/340R Sport Seat and the S2 Exige Sport seat? Or more importantly any upside or downside with fitting the later seats in the S1?

I believe I need different runners…anyone got any idea roughly how much these costs?

Thanks in advance

Yep, pretty much identical bar the runners as you say.

i’ve fitted s2 probax sports seats into my S1

I had to modify the front of the seat frame a bit to provide a mounting point for the front bolt holes, then it was just a bit of grunting to get everything lined up… possible tho

not fallen out yet!!
