Have you ever driven a car with a full set of plastic bushings? As long as the rest of the suspension is in good condition (damper, springs, ball joints, etc.), everything will work better, or at least as it should. I bought them for a 2000 AP1 S2000, front, rear and diff, now I need better tires. Simply because they are now the weak link in an amazing machine. Installation isn't easy and takes some time, but for the money you can't get anything better. Thank you energy!
