Just purchased Calipers, rotors and brackets to convert my tiny NA brakes to larger sport package. My question is, has anybody installed the Sport Dust shields / backing plates onto the NA spindles.
Will the newer rear shields press on like the NA shield and will the front bolt up? I have the opportunity to get these brand new at a very good price. Seems like a very clean way to alter the backing plates to fit. Also as far as I am able to tell the law requires vehicles in Canada to have the backing plates. DOT inspector friend told me they are required to protect the rotor/pads from getting wet on a street car. Braking reaction can be reduced by up to 1 sec to clear the thin film of water off of cold brakes. Race cars different story.

Part #s:
Rear - N06726261
front R - NC8233260A
front L - NC8233270A
EDIT: Answered my own question with a little help from google translator and a DIY Italian MX5 site, yes sir, yes it fits just like it should. Italian's have such long nice way of explaining things. ROCK ON!!

Thanks
