Check out the
badge requirements.
Also, if you go into the details of each item, it will have its point value.
Floor mats dont have any points.
The cheapest item on their website would be the
2 front strut bars. It's worth 1 point, but they do have a note stating "For use in conjunction with the Dinan Strut Tower Brace." maybe you wont get points unless you have the main strut bar as well? Maybe sell the 2 strut bars you have now and replace with Dinan to get the badge.
Otherwise, forget the pedals, and go for two points with the
software upgrade at $299. More practical I think.
