My TE37 has similar suspension is some ways.
I have used ST162 Monroe strut inserts I think, on the front. I cut the strut the full 63mm or whatever it was and used no spacer. I also have coilovers with 325lb/in springs (about 6kg/mm) and the spring/shock combo doesn't seam that bad. I have it so the top of the tyre is about level with the top of the wheel arch, but the wheel only drops about 40mm when I jack it up. This is mostly ok, but on Targa Tasmania type roads, a front wheel will skip sometimes, which does not upset the car realy but its a loss of traction I could have used.
The back springs should be softer. I have leaf, and they are probably too stiff. I also have Koni red shocks to suit a Commodore wagon. On the stiffest setting, the car is almost undrivable at speed, over any bumps. The back suspension just packs up and becomes too stiff. I cannot go as fast like that. I now have them on the softest setting, which is probably a similar rate to Monroe replacement shocks. I plan to take the extra leaf out so the rear is closer to standard stiffness.
But with the AE86, I think 6kg front / 4kg rear springs with any shocks in ok condition, and a few polyurathane bushes make for a good handling car. If you have adjustable shocks, you probably still want them on soft with those rates, up the back at least. It depends on the shock.
Try driving fast on a bumpy hilly road, or even off road. You will learn more about suspension that way. The racetrack is more forgiving.
