Bad/Good springs/shocks

[20vWill]

I have

Front: T3 coilovers, 40mm cut case, AGX short stroke insert, Eibach 4kg/mm, T3 camber tops, BattleVersion NCRCA, TRD ARB.

Rear: Cut AE86 lowering springs (unkown rate, but too soft!), Isuzu Piazza shocks, BV adjustable 5 links, TRD ARB, cut bumpstops.

The front is great. Short stroke configuration improves ride quality and handling beyond all expectations. 4kg is a softer spring than most use, but my car sees mostly road use on crappy tyres. The TRD rollbar helps tame body roll and there is very little now.

Rears are a bit of a pikey makeshift set-up. I'm looking for a rear spring of about 3kg/mm but haven't gone custom because they will never get the ride height right so why bother? I'll just keep experimenting with various springs of a similar diameter and stiffer rate until I'm happy...

The Piazza shocks are a fair bit stiffer than stock and are VERY short to keep the shortened springs seated. I've got some AGX to try for the rear but I haven't fitted them as yet.

Currently the set-up is undersprung at the rear so handling is quite safe and grippier than I'd like. With a spring closer to 3kg, I should have a nice balance for road and occasional track use.

Most people with AE86's run rates far stiffer than they (and their tyres) will ever need and too stiff for an unreinforced unibody. A lot of this is just following trends of what others do, rather than thinking about their own specific needs...
