If you mean 'make more negative' then yes.

They look to be longer in the x direction if you know what I mean. Like the original SPC arms for G37. If that is the case, this length will offset them being 'lower.'

For those interested in the max alignment allowance on these puppies, here are some actual results by a vendor on a 370z (and confirmed by the prototype tester)

I am not sure if the vendor is in this forum or not, so I'm attaching a screen shot instead of linking to the sale thread.

Thanks, regarding going positive, I believe 0 camber will be max, lowered on Swift springs.
Im looking at -2 right now, and have 1 maybe 2 threads left.
Going to alignment shop this afternoon.
My goal is to return to -1.
Ill take the +6 caster they preset in order to keep the neg camber on turns.

I simulated a full swing before attaching the ball joint, and compared the to the SPC, and they can travel higher, they fit the inner fender recess very well.
Looks like SPL took this into consideration.

OK we went with -1.4 camber and 5.9 degrees of caster.

Still have room to go. Dropped on Swifts these arms will put it in the OEM -0.8 sweet spot.
I don't believe they will fully compensate for a lower drop.
SPL did tell me that these arms are engineered for 6.0 degrees of caster with bolts being equal length, and that is true.
I love having extra caster, makes the steering tighter at high speeds, and get a little more negative camber on turns!!

Spherical bushings are the way top go! Better compliance in the front.

I still haven't found any downside to these arms.
