In my book, roll center first, camber gain second, bumpsteer third.

roll center is definitely first, and I would say it is pretty much a toss-up on the other two. All three are factors that must be taken into account though.

If the is a order of importance (I THINK THEY ARE ALL IMPORTANT) I will say that roll center location on any car is the most important, if you use a full size frame then the camber gain, but if you use a small metric I say bump steer is the next in line....the bump steer on the full size cars isn't tooo bad, but the bump on the small metric is sooooooo far off it becomes almost as important as roll center location....

When locating the front roll center you can use different parts that correct 2 or 3 of these things at the same time..........mostly roll center and camber gain........then the bump steer can be corrected after, that is isolated from the roll and camber anyway..........

So what changes would you say are needed or would help to correct roll center on a stock stub?
Upper a arm angle
Lower a arm angle
(in order of importance)and what would the roll center target be?

I added the AFCO lower ball joints(tall) to my metric on both sides(because i noticed they didn't make easy replacement ones for the top)...does this help anything? Is that how you help the roll center?
