GR86 Sketchy rear end due to alignment change overtime

[Stardus.]

Just a reminder... Check your alignment if it drives weird

My GR86 was set to zero toe rear as a test 4 months ago and recently I have to catch the rear unexpectedly quite a few time. The car feels super nervous and had no rear traction, I nearly blamed it on the weather and the F1 SS not being good in the colder weather.

Nearly... It turned out the zero toe have moved into a slight toe out and really changed the character of the car!

Swapped to slight toe out front, and toe in rear. Now the car drives like how it should have been again...

Reminds me I need to find a new alignment place as the one I used who were a motorsport company, decided to close and move into other things. Mines fine for now but always got future plans.

I seriously consider some sort of lockout kit for rear toe like this:

FR-S / GR86 / BRZ fixed adjustment eccentric toe lockout kit

The GKTECH eccentric lockout kit replaces the adjustable toe arm bolts that are prone to slipping under hard driving conditions and ensures that your wheel alignment stays where it was set. The advantage of the GKTech eccentric lockout kit is that our washer kit does offer fixed adjustments so...

Geniuly no point messing with it if your intentions arent very specific (track focused), for most of the people, maximum toe in or netural, would be the best.
Drift setups, toe-out and call it a day.

My idea of setting it to netural was a mistake with the standard toe bolts. They slipped only lightly but to toe out overtime and just in time for winter.

I would recommend maximum toe in for daily driver and call it a day. Even if it slips, you won't have your rear suspension crossing from toe in and out through out the travel this way. 13 minutes of toe in per side would be totally fine.

The GKTech kit for lockout would be ideal if you have adjustable toe arm. Fine tuning is still important, and you won't have it anymore using that without a adjustable toe arm.
