Cpt nailed it. I also find that more caster has more exit steering on low speed turns, almost making the car hook. But I have to test that more.

Caster is faster. I find less caster gives more turn in but less steering in the middle of the turn. With more caster it seems more linear throughout the turn. You can also think of it as the more caster you have the more the car will dig in at higher speeds.

Curious, for those of you running the 30 degree kickup have you run the inserts backwards so you would get 28, 26 degree caster? I am just wondering if the results would be similar to running 25 kickup with different inserts.

Worn down tires so that the pins are barely visible.

Only bad question is the one not asked.

Yes that I understand. I was just curious to see if anyone tried it and how it felt.

I am actually going to make this change for this weekend. I want to lower my caster, but want the kick up for off throttle rotation. I am going to try 30/-4

So this will equal 26*? Achieved by just flipping you blocks to the opposite side?

I was thinking of trying 29* I want more mid and exit steering right now. Maybe ill try the red springs again as I have gold on right now.

Also, which front hinge pin holder is the thicker prefered one? Seems like there are quite a few to choose from? Part number?

This is the latest one that has been refined, KYOUM720B. I put it on my car last Tuesday and so far so good.
