GedneyHi Gedney,
If you have the factory wheels on your Mazdaspeed you would want to get the 12mm x 1.50 20-piece lock System. Our locks are 1.4" overall, which translates to 35.5mm.

GedneyYou should be good, just need to make sure the wheels are cone seat and that the lock socket will fit. The key in these sets is 1.1" wide, about the same as a 13/16" thin wall socket.
GedneyHi Gedney,
I do apologize, the kit that you would need with only 20 locks is not available through this drop. As Lukas noted above, there are some kits where market pricing is too low to be able to include them on this drop. If you have any other questions feel free to contact me directly at (800) 262-6267.
