Glad to hear you are out blatting and enjoying it ....I am very jealous of the roads you have on your doorstep.
About the seat did you end up making just a base or a back as well? Also when I made my first one there was no way the bag was going to part company with the foam ....it was pretty well 'integrated'. Did you also use a plastic seat base and if so outside the bag?
Got any trackday plans for next year now you have the seat?
Cheers
