Increasing caster will increase the effort required to turn the wheel, And also make the wheel snap back to center faster. There is no tire wear associated with increasing caster, just steering effort. So i like to run as much as possible, especially if you are going to drift because you can get that opposite lock going faster

just disconnected the connector on the rack and it made a HUGE difference. the steering is really heavy, but not difficult. I need an alignment so when i get it done, I will have them adjust to have more caster. Will they charge extra to do that?

Are there any negative effects from disconnecting the plug?

Ditto.

Just in case anyone wants to do this, you can reach the connector from the top. No need to jack the car up.

They shouldn't

I would research and decide what alignment specs you want.
If you keep toe stock, .8* of Camber front, 1.5* of camber rear, and the most caster possible, you will have slightly more tire wear but also improved handling.

It's not hard, its very easy. And if the place you are going to doesn't know what Camber, Caster, or Toe is then GET OUT lol

disconnecting the plug on the rack will provide a heavier steering while driving under 40mph or so.. but during highway speeds or spirited driving, I wouldn't recommend it.

At higher speeds, the power assist feature provides a tighter steering response. Without it, the steering wheel feels very sloppy/loose..

I don't see how you can still have stock feel with the plug disconnected and the car moving at highway speeds.

The steering can't feel the same.. With the power boost, assist whatever its called (LOL) disconnected, the steering feels heavier. That we all agree with. At low speeds the steering feels stiffer, if you will, because the weight of the vehicle is on the front tires.. As you begin to gain momentum, the weight transfers to the rear, allowing the steering to be easier and not as heavy, almost a sloppy feel to it..

With the power assist connected, this prevents the sloppy feel and provides a tighter steering..

Again, this is all from what I am feeling... I could be wrong..
