Post Photobucket reboot from June 2013This is a top tip from NickW, following my recent photo from our last factory trip of the reshaped sports seats with additional shoulder support.
The backrest of the standard folding/reclining sports seats are only secured top and bottom. This means that you can get your hand behind.......

Nick has used memory foam, but I, naturally have used 4mm standard density neoprene........
I started out for one seat with 9" wide by 16" long, the idea was to fold it over to get 8mm thickness. The eventual width needs to be a shade under 8.5" so it doesn't show.

The next step was to secure the folded neoprene using my trusty selction of double sided tape. One length on the fold to keep it tight:

Then two more strips to hold it together:

Once stuck down, I trimmed the edges with Mr Stanley:

And slid the neoprene into place. It needs a firm pull to get it right to the top where the shoulder support is needed:

This photo shows the drivers side done and the passenger side still to do. I think you can see the difference. Ignore the wet patch, I have been cleaning off the black marks inside the hood!!!

The beauty of this modification is that you can use a variety of things to do it, sponge is one, neoprene is another etc etc. Then it takes minutes to do, and can be undone in seconds.
It feels a lot better, but needs testing on the road.
