drift button for almost all jdm cars. 5mm x .8 thread. if using a .4 nozzle, you will need to run a tap through. if using a .2 the threads should be good but should probably still run a tap through. (a1 mini .2 profile coming soon) regular round, star, or heart versions. definitely fits mazda miatas, mazda rx7 fc and fd, mazda rx8, nissan s chassis and skylines, toyota supras, jzx90-110. probably all jdm cars, but all of those wil accept this button.
