I've got the sr3s! So far I've just put in one. Gotta get onto insurance and engineering just to be safe, then I'll chuck in the other one.

Warning if you want sr3s, they are tight in the hip area. I have a size 32 waist and it's ok, but a bit tight. Turning around when reversing is a bit of a bitch. With the low driver's rail, I have an extra 10 or so cm between me and the roof (head used to nearly touch the roof in the stock seats).
As uncompromising as they are, I like the fact that now I'm low to the floor and feel spot on in touch with the handling.
