Explain TEMS to me
 

So I picked up the supra we will be prepping for the 24 hours of lemons race - on the console between the front seats are 2 rocker switches - one that sAYS tems.

What is it - will it help me? how do I test to see if it is functional?

Carl Johansson

it has a mechanical servo
that somewhat dampens the ride wich in turn gives you a little bit stiffer suspension, and lesser body roll, somewhat
in corners or when hitting a bump
youll kinda feel it

the only way i noticed it b4 was, when i had it in sport mode
i hear lesser rattling in my car when i hit bumps

Heres a writeup on Tems function.
