Thanks all.

I in running 17x8.5 +53 in the front, hence why I went up to a 245. 17x9.5 +63 in the rear on the 255. I used to run conti dws with a far weaker sidewall on the same wheels in the 225/255 stagger and had the steering feel I wanted .

I always thought more caster would stiffen the steering? On that notion the wheel does not fully self center, it goes maybe 10-15 degrees off and then stops and I have to steer it back to center.

It does in a way yes. More caster will "ovalize" the steering to wheel relationship, so as you turn in the steering/wheels gets sharper, this also makes for a quicker return to center. Camber has an influence on this as well, as more camber will increase turn in, and compounding the effects of higher caster settings. However, your ride height has a sweet spot for all this to work together, and if your dropped to low as you mentioned in your other thread, the geometry of your suspension and steering points will be pretty out of wack and start changing the rules on how your components are influencing one another, as well as your alignment settings. The toe arms up front which control your steering inputs get pretty severely out of alignment from their natural parallel alignment when closer to stock height, and this no doubt has to have an influence on how quickly the steering can return to center, as well as toe change under suspension compression. 13" from fender to center hub is pretty ideal. Much lower and you have to start making component changes to re align everything.

All we can do is throw out educated ideas based on our experience, but unless one of us can actually drive the car and feel ourselves what its doing, all they are is guesses.

Generally speaking, it’s never a good idea to change more then one modification at a time. Certainly if your experience level is low.

Good luck!

Thanks, it all make sense. I was never really really low just lower than it should have been. I'm now at 13" exact in the front and about 13.25" in the rear.

Glad you got some answers. But not a Racing and Competition thread. Moving back to suspension section.
