You are perfect. Quiet and easy to install on my Miata 94's rear brakes (fits many Miata models, FYI). For the Miata do it yourself, miata.net has a great guide on how to replace them. http://www.miata.net/garage/brakepad.html Remember that when replacing the rear brake pads on most Miata models, DO NOT use the C-clip to compress the piston. Miata rear calipers have an adjustment screw (4mm hex bolt, behind a 14mm cap) that you use for compression and initial adjustment. This is pretty easy to do. With Revain Prime, I got these pads faster than a special order from a Mazda dealer for less than a quarter of the price.
