Wanted to get a couple spares and checked around (Rockauto, Advance auto, etc...). They all suggest the fronts and rears are the same size, specifically M20x1.5mm. This works great for the fronts, but the rears are larger. Anyone know what size the rear nuts are? TIA Willie

They are the same size OEM(1.6 axles). But if you are running a Torsen with newer 1.8 axles these are different. Google a 99 axle nut(sorry...I dont know the size other than it takes a 32mm socket). Early 1.8 axles are the same as a 1.6 axles(nut that is...not length)
Edit...with your Mazda account a simple phone call gets these on their way to you!
