Last week my order from www.JDMBits.com arrived!
A new camera mount! This is one i had not seen yet. it is J.P Sunvisor Camera Mounts for the Mazda Mx5 Miata NA and NB
 

I still have to test it, but the quality looks great!!! 10th of march i am going to to the first slalom race of the year @ wimedo lelystad. So will have a better verdict by then!
