AE82 (FX16) - AE9X suspension upgrade


MountainTuna69

Recommended Posts

Hello All!

I am new to the AE82 chassis but not new to Toyota at all.

I recently imported an AE82 rally car from Denmark to the US with the intention of gravel rallying it here. However, gravel rally suspensions are almost impossible to find save for a few extremely expensive options.

 

In my research, it seems that it’s possible to bolt up AS92 coil overs to the 82. Can anyone confirm? There are many more options for the 92.

Sell it and get a RWD!!  ...or a 4WD as all those models had 4WD Tercel options.

What shocks are in it now? Why change?

Your problem is simple, you need gravel suspension. There 's a good reason the shocks are turned upside-down for gravel, it puts the outer shaft in the top bush and keeps the thin shaft protected down inside the tube so it doesn't get bent. Also, gravel shocks extend very easily and compress with difficulty, to keep the car high. Tarmac shocks are the opposite and suck the car down onto the road all the time.

As I'm sure you have found, all the aftermarket coilovers are tarmac designed, and usually can't be re-valved for gravel. In the good ol' days struts were 'wet tubes' so came apart into a hundred pieces and the valving could be changed at home. Since the 80s its cheaper to manufacture sealed units so they cannot be re-valved.

So going to AE90 stuff probably won't help, you will still have a shock that pulls the car down and now has incorrect geometry. There are a couple of companies in Aussie that manufacture shocks, but at $8000 a set you have to be pretty keen! In Sydney there is a mob that re-valve Bilsteins for RWD Corollas, both front and rear come out of heavier vehicles so the shocks are built heavier than Corollas. The fronts are still upright though. MCS and their new offshoot start from scratch with just the hub foot and run remote canisters for oil, hence the heavy price.

You're still better to put a cage in a 4AGE powered RWD Corolla GTS or whatever the AE86  was called over there! FWD sucks on gravel!

Ok, here's the parts list for the AE82 FX16-

..and here's the same for an AE92

You'll note the struts are the same, as are the shocks and springs, so there are no differences there. However the AE92 only has shock inserts available, while the AE82 has both inserts and wet struts listed. The wet struts can be re-valved at home.  Zerotohundred.com say that they are the same struts through AE101 & 111 except for the super-strut models.

Barry Manon lists them separately, although they look identical... Stock photos I suppose. He could valve a set for rallying I'm sure.

Did the AE82 come with suspension and geometry data? ..and how much travel can you get in the back?
