Try it... you may be getting assist that you're not aware of.

i'm done for the season but my friend's off to the final trackday of the season. Let's see if this works! Cheers, Steve

My friend who tracks it all the time DOES experience this a lot more severely than I do. He has the koyo radiator and an earls oil cooler and I am not sure you can 'overheat the motor' with these mods. He also drives on our F1 circuit as well so it's certainly not a heat soak issue?

I meant the power steering motor, it's a small electric motor on the steering column. The owners manual specifically calls out that this motor can over heat from time to time.

Thanks. If the steering motor is the cause i wonder how it happens. Too many 'heat cycles'? I need to find a solution quick because it is starting to feel like those old logitech wheels I used to use for gran turismo 3 lol

Anybody know if it is the elec motor that overheats or the driver box? Maybe some cooling air diverted to both would help or at least change its time before it happens. Can't wait until steer by wire overheats.

I cannot explain how much I hate when this happens. Weird thing is when you turn on VSC sport mode on, the steering dynamic is more natural, but when drifting and turning of traction control, the electronic steering assist stays on. It feels like I'm fighting the wheel.

Takes some getting use to. I just need more seat time.

another bump.
im hoping to rectify this issue with the perrin offset psr ensuring higher and even dynamic caster levels and additional bracing upfront.
could this actually be some sort of crazy bumpsteer/roll center issue? i realized that i am actually lower than stock by about 30mm. i am thinking it isnt a geometry problem, given some other local 86 owners experience this at 10mm lower.
i guess i will keep throwing parts at it until i can work out what it is!! lol
