Anybody heard of this before? I just saw it on a website talking about mazda cars.

Something to do with the rear suspesion allowing the rear tires to turn to aid in sharp turning or something?

Twin-Trapezoidal Link (TTL)

anybody know what mx-3's have this and how it work?

Yep.

The MX-3s have the TTL Suspension set-up in the rear.

This is one of the reasons that the MX-3 handles soooo well.

Quote from Wikipedia:

The MX-3 used Mazda's proprietary Twin-Trapezoidal Link (TTL) for the rear suspension. It passively allowed the rear wheels to turn slightly in order to enhance handling. It has been used on a range of Mazda vehicles, providing a smooth ride, yet delivering responsive handling while minimizing body lean.

yep its just off of the main MX-3.com page...http://www.mx-3.com/brochure/intro.cfm

The patented Mazda Twin Trapezoidal Link (TTL) independent rear suspension works to deliver some of the benefits of 4-wheel steering, such as quick response when you change lanes or turn corners, but does it without added weight, complexity or cost. TTL automatically maintains the best alignment of the rear tires to the road surface, improving both stability and agility.

The super hicas is 4 wheel steering and different from the TTL setup that the MX has. I would recommend google.
here is what I found in 30 seconds...

HICAS (High Capacity Actively Controlled Suspension) is Nissan's rear wheel steering system found on cars ranging from the more recent Skyline and Z iterations to smaller models like the 240sx. It is also found on models from Nissan's Infiniti division, such as the Q45 and the M45/M35. Unlike other four wheel steering systems, Hicas and Super Hicas is fitted to improve handling rather than as a parking aid.

Earlier HICAS versions used hydraulics to steer the rear wheels. The hydraulic system was powered by the power steering pump and used speed sensors to determine how much and which direction to steer the rear wheels. Later versions, called Super Hicas, moved to an electric actuator for the rear steering rack, making the system much lighter. The Super Hicas system also used its own computer to control the system insted of speed sensors. HICAS and Super Hicas rear wheel steering is limited to about 1 degree in either direction.

This is pretty much why mx-3's are the s---.
