Bump steer refers to the change in toe as your suspension moves through its range. A lot of bump steer can lead to unpredictible handling as the front wheels basically steer themselves when you hit bumps or the car rolls in a corner.
When you change the ride height of a car, you can introduce bump steer. The Miata is pretty good in this regard, but if you want to go beyond "pretty good" here's your solution.
These tie rod ends were introduced in 1993 on the LE model, to compensate for the lowered suspension on that car. They were also used for the 1994-97 R package cars. The stud is about 3/16" longer than the tie rod end used on other Miatas. It's a good match for our FM springs or a coilover set to a reasonable ride height. If you're slammed, they may not be enough for you.
Includes all hardware needed for installation in case your stock nuts are all rusty.
