I haven't weighed the old seats yet (still for sale by the way

Couple of questions:
I want to use self expanding foam behind the new seats to give a little extra support for the seats themselves. The seats seem very rigid, but for a tiny amount of weight, this seems to make sense. Can anyone recommend a particular brand, or shall I just use what I can get down at B&Q ?
Second question - the centre tunnel needs re-covering. Where can I get CF or CF look-alike at a reasonable price ?
Thanks,
Pete
