Also some MkIII supra's came with Progressive Power Steering. Looking at that system it might be easier to adapt to the celica but still its part electronic and would require more effort than a mechanical bleed/shut off valve.

I haven't read through the 5 pages , but jut in case no one else has mentioned it...

CASTER!!!

Caster has a huge effect on steering & car feel.
I run about 4deg and want more. It along with larger sway bars, stiffer springs, decent tyres and poly bushes has made a huge difference.

Yeah, caster has been mentioned a lot. So what are you using to adjust caster?

MWP · Nov 23, 2011

I turned my adj strut tops 90deg to get the caster adjustment.
I need coilovers and custom strut tops to get more than the 4deg I have now.

I dialed in more camber with crash bolts.

I am likely going to try that method. The dual adjustable tops look like a pain to setup.

I swapped & rotated the strut tops on my teins and it totally screwed my kingpin so once I got more than 1.5ish of a way into a turn the wheel would go to full lock and not recenter without me pulling it back :roll:

Did you get it wheel aligned after doing the swap & rotate?
Adjusting caster (or camber) throws out your toe settings, so you always need a wheel align after.

What tires size are you running? Any rubbing from that much caster?

225/45/17, and they have plenty of room (on +39 offset wheels though

).

Adding caster doesnt effect tyre position when the wheels are straight ahead.
It only only effects position slightly during turning (tyre moves towards the back of the car a fraction).

They are popular because the PS Pump is powered by an electric motor, not the engine.
Besides that, the power steering system is no different to what we have.
