I just wanted to improve and restore the lost roll center. Especially since macpherson strut suspensions want a lot of camber. So these also help me minimize camber loss. I also wanted to improve the roll axis

I totally understand the reason to fix the roll center. I'm just wondering how people are settling on the sizes and parts used. How do you know where to move the mounting points to improve the geometry?

Gotcha. I have the software that we use to measure roll centers for circle track cars. I never took the time to measure my FC though. It's a time consuming process to measure the X,Y, and Z for all the joints in the suspension. However, If you ever want to take the time to measure everything on your car I'd gladly enter the numbers into the software and share my results.

when I first set my car up with roll center adjusters I set the tie rods to be parallel with the control arms... I later measured with a bump steer gauge and it was pretty far off. ended up going up about a 1/4" on the tie rod at least. so definitely measure your bump steer
