As usual with MX5parts excellent service. Contrary to what anyone says you DO NOT need to remove the rear bumper to fit this diffuser ( mine is a 2010 3.5). If you get a torch and a damp cloth and wipe the inside of the bumper you will see small circles with a cross marked out where you need to drill holes. Take a sharp object, bradawl or similar and push into the centre of the cross this will make a mark on the outside which is where you drill. From start to finish 2 hours- put it on ramps, clean inside bumper, locate embossed marks and use brad to transfer location to outside, double check marks line up with pre-fitted bolts on diffuser if happy drill holes, i used a 1mm smaller drill than Mazda suggested, fit diffuser, tighten nuts and stand back and admire.
