Alas, does not fit the Series 1 apparently
I had the same concerns with my S1; spoke to Cain a few times about a suitable fitment but I think it was so few numbers and he was very busy.
In the end I got my local garage to take some measurements and then had a sheet of Ally laser cut at a local fabricators.
I drilled four holes to aid cooling and used Sikaflex to fix some S/S mesh to the reverse (to stop any stones acting as missiles!)
Back to the garage and they then fitted it for me -

Sorry, not the best pictures but you get the idea

Like others, it has saved the car from (severe) damage on at least two occasions......
