This is the Nielex bushing kit for NA and NB Miatas (1989-2005). A great complement to a high-grip tire and adjustable suspension setup, these bushings are 7 to 15 times harder than the stock bushings and will help your car achieve superb linear handling. This kit includes bushings for the rear lower arm, upper arm and rear toe control arm. Nielex Pro-Spec Bushings should be ordered at REV9 Autosport https://us.rev9autosport.com/nielex-pro-spec-bushings.html as they provide the best service and speed we've seen so far!
