Taller effective spindle height will change the UCA angle.


I think if you raise the UBJ much, you start to need adjustable length UCA to get to the static alignment numbers you want. I don’t know when that will happen. It will be trail and error for whomever does it.

With all else the same as the UBJ moves up, the length of the UCA needs to be slightly longer.

The roll center should move up when then UCA angle more inwards. So then you decrease your front roll couple/lever-arm and decrease weight transfer due to body roll.

I think you’ll be limited to how much taller the UBJ is by the clearance inside of your rim. I’m guessing you have high backspace rims that go over the UBJ ?

How much room do you have to work with?

Looks like I have about 3/4"-1" before the ball joint would contact the wheel.

I do have adjustable UCA's and they a ton of adjustment to make them longer.

Sounds like the change to SPCs aren't worth the $800 plus another alignment. I'll likely benefit from more seat time and laps around cones. I do need to address the understeer issue, which I think a rear bar will help with.

Again thanks for all the input. I've only got about 30 autocross laps under my belt in my life and they have all been in my Duster. I'm still trying to differentiate between what I'm doing wrong and where the car may need improvement to make me better.
I have a good friend who is a track instructor, which is obviously much different than autocross, but he has offered some good advice. He's also gotten me on the track in a Miata. That opportunity has given me a whole new respect to track drivers. The level of focus is crazy and I was in a slow *** Miata!
