Rear suspension
The rear is leaf springs, like all corollas up till the KE70 series starting about early 1981 (or 1979 in Japan). To stiffen them I have used Wagon main leafs (a bit thicker) with normal coupe leafs and a extra leaf from a wagon. The wagon leafs are different lengths so the pack is still of different lengths. I have a selection of different leaves which can be used to change the stiffness of the back. To lower it (and to counter the extra hiegh the extra leaf gives), I have tuned one leaf upside down. If you have a wagon, the thick bottom leaves (helper springs) should not be used, as the thick ones effect things negatively when you lower it. The bump stops can be cut in half to regain some travel. You should not lowered it too much because the rear shocks are mounted at an angle so lowering greatly reduces the effect of the shocks. It would be good to relocate the top shock mount so they are verticle. Turning a leaf spring upside down is not the best, but a cheap way to lower a bit. Idealy, the springs should have lube or some plasic spacing between them so they can slide against each other, and just work as a spring like they should and not bind up, letting the shock do all the damping.
