... The 1981 through 1983 chassis has one suspension featutre which is the chosen feature over the 1984/85. The chosen feature is the rear lower link forward chassis pick-up point is approx 3/4 inch higher/closer to the bottom of the chassis than the 1981/83 cars. In other words the chassis pick-up point is 3/4 inch higher compared to the normal center line or the rear axle. ...

Dave, are you saying the 81-83 is more desireable because the pickup point is 'higher'? I think your years/wording got intermingled (81-83 chosen feature ... better than the 81/83?) causing me confusion. The rear links were lowered 20mm for 84/85. From some rx history for 1984 model changes... "Mazda reduced the tailhappiness of the RX-7 by lowering the rear trailing arms by 20mm. .... The rear suspension alteration was applied to all models."
