Positive camber on rear wheels after installing spring relo kit and SS springs

Looks like my wheels are showing a bit of positive camber after the following work on my rear end:

1) Mopar spring relocation kit installaiton (used for more clearance with larger tires)
2) New SS springs (P3412002/3)
3) new 15x8 wheels (moved from 15x6.5's)
4) new 275 60 R15 tires. (upgraded from 235's)

Car is a 1972 Plymouth Duster which I primarily use only for bracket racing. It is on the street but doesn't go there much except for a test drive or cruise-in that is w/in 5 miles.

Questions:

1) So positive camber looks bad. Is it an issue? How to best address the condition.

2) I'm in the lower hole on the front bracket of the spring relocation kit. Differences between upper and lower holes (obviously ride height) with respect to racing?

Thanks,
-Rob
