1986-92 RX-7 Rear Suspension Upright Toe Eliminator
On the 1986-92 RX-7s Mazda introduced the Dynamic Tuned Suspension System (DTSS). DTSS allows each wheel to steer by itself based on how many Gs of cornering force the outside wheel is generating. In stock form, cornering forces operating on the rear upright cause up to approximately 1 degree of toe-in on the outside wheel in a turn. This characteristic tends to compensate for driver input or road variations that might cause a vehicle to go out of control. However, this same characteristic also interferes with the feedback that a sensitive driver needs to operate his car near the limit of adhesion and generally reduces the ultimate cornering force.
Our Toe Eliminator - a rigid joint that replaces the stock rubber joint - provides a perceptible improvement in feedback to the driver. There is no longer a need to modulate inputs based on the constantly fluctuating elastic joint output. The kit consists of two (2) rigid plastic sleeves and two (2) steel bushings which should be installed with the aid of a hydraulic press or a large vise. No re-alignment is necessary after installation.
What you could do is put one of your rear wheels back on. Have someone move the wheel back and forth. look where the play is and look for a sim joint. It should be in front of the axles. I may be able to stop by and see if I can find it some time.
My guess is it is where the toe in adjustment is.
