I setting up my car for HPDE use and want more negative camber

Here are the solutions I have heard of

1) SPC adjustable ball joints

2) Upper arm bushings

3) adjustable lower control arms.

What has worked the best for you (I want to get +5 in caster all around, 0 toe upfonrt, and 1/4" total tow in rear)

 

Are you using stock suspension. I am running spc ball joints and have 3.4 camber and 7 degrees of caster. I have previously also used the j's offset lower ball joints as well. The bushings will not give you much more and they can cause interference with some shocks. I'm using the ba on joints because it allows me to pull the top of the suspension in which gives me more clearance for the 18x11 wheels with 315 race tires. This is on a autocross car

 

Offset lower ball joints. Absolutely the easiest, cheapest and most reliable way to get more front camber.

 

Agreed.

 

I think offset bushings are easier/cheaper but I like owning tools

 

+3

 

I'm running Bilstein PSS9s so a bit lower than stock.

 

Offset upper or lower ball joints achieve the same goal, with the uppers pulling the top of the suspension in (more fender clearance, less frame clearance), and the lowers pushing the bottom of the suspension out. So you just want to make sure that whatever wheels you are running have offsets or spacers that will result in the final wheel position working for your ball joints and available space. If you happen to need your particular wheels pulled in a bit, uppers are a great way to achieve that. If your wheels are already fitting well up top, using lowers will keep the top of the wheel in roughly the same spot and push out the front track for additional stability and grip.

Most lowers are also available with roll center adjusters if you happen to want or need that as well.
