This is all by theory though. Compared to the write up a I have read and their site
In comparison, SPL offers an adjustment range of -2.5 max in relation to stock height. Meaning if you lower your car, whatever your camber is, you can add another -2.5 to that number until the arm is maxed out.
In other words, if you are lowered and your camber has changed from stock settings to -2.5. SPL will add another -2.5 making it a total of -5 degrees of camber. That's if you wanted or needed that much.
When lowered with a setting of -2.5, the Z1 race version control arm will add another -3.5 making your total negative camber -6.
The Z1 arm also offers a good range of adjustment to go less negative. So much so that it can get you to +.25 at stock height or lowered 1". Due to the ball joint hitting the chassis, you will not be able to exceed +.25. So, if you are lowered 1" with the stock arm and your camber is -2.5, adding the SPL arm will give you 1 degree making your camber -1.5 max instead of -2.5.
See the chart below. The 1.5 stock height is only a reference point and your car may not have a stock camber of -1.5. Please keep in mind that the numbers will vary with each car do to the tire size, wheel size, and ride height. This chart is not showing arm limitations due to the chassis.
Maximum amount of negative
Minimum amount of negitive
If you were dropped more then 1-2" you would be able to get closer stock settings out of Z1 arms then you would the SPL. Same with going negative, you would have more - adjustment as well shown in the chart above.
