What the hell is camber? - Good question. From this web-site: TurnFast! • Glossary

Maintaining zero camber provides the largest contact patch, however during cornering, the tires roll decreasing contact patch, and the suspension geometry changes which further reduces the contact patch. To counteract this, a car set up for maximum cornering grip usually has a small amount of negative camber from 3/4 of a degree for street/track setups to as much as 3 degrees for dedicated race cars. Too much camber reduces traction during braking (and accelerating for a FWD car).

However, all of the rest of the info is dead accurate today, still very relevant, and it's brilliant. Like this for instance:

As front camber is not adjustable on our cars it is important to make it so. Stillen, Cusco and Ground Control make high quality camber plates, the Ground Control being the best of these as they give you 1/2" more wheel travel and the ability to adjust caster. Camber Plates will slightly harshen your ride but will sharpen turn in due to the elimination of squishy rubber with metal bearings. Rear camber adjustably is not critical on most FWD cars. If you are on a tight budget and cannot afford camber plates, you can use The Poor Boy Method for adjustable camber! To make poor boy adjustable camber, you can drill out one of the two strut to spindle bolt holes on the strut housing by about 1/16" This will get you a couple of degrees of camber adjustment. Camber bolts or crash bolts as they are sometimes called should not be used as they slip under high load. If you are racing Solo II stock class or Showroom stock and don’t want to cheat, you can get about ½ degree more negative camber by loosening all of the suspension bolts and having someone hold the wheel in the negative position while you retighten everything. When adjusting camber, be sure to reset your toe adjustment as it will also change when you adjust camber.
Now that we know what camber is, lets look at hardware to adjust it on a B13 vehicle.
Camber bolts or "crash bolts" - A few companies make "kits", Eibach, Whiteline, Ingalls, etc..... Pretty lame way to adjust camber, it will shift under heavy load. If you are serious about autocross or road racing, you will buy a set of camber plates.
Here's a good thread on camber or crash bolts:
camber bolts anyway had/have these? - SR20 Forum
Pay attention to BigB and Jerryeads.

Common to both center look and camber adjustable type improves steering response and performance. Stable steering response in esesse and lane changing improved stability over bumps and holds roll in corners. Enables linear handling and keeps you on the record line better. Stability and safety during turn-ins and under braking.
SPECIFICATION
Available for both center lock and camber adjustable types
6mm thick plate made from 2017S heat treated aircraft grade aluminum.
Various pillow collars available to suit your needs.
CAMBER ADJUSTMENT
Camber adjustable by sliding the plate and
pillow ball sections

Ground Control camber plates work with coilover springs only. They do not work with Nissan stock or direct replacement springs.

Camber and caster are separately adjustable by sliding the mounts, without removing any components from the car. The priority of this design is to allow fast, repeatable alignment changes at the track.
The Ground Control camber plates feature two sets of bearings, a proprietary bearing, made to our specs by Aurora in the USA, which allows for articulation of the shock shaft. This spherical bearing is very understressed, as the Ground Control design does NOT support the weight of the car on the spherical bearing. Instead, the weight of the car is supported by a completely separate articulating needle bearing, which is also manufactured for Ground Control in the USA
MSRP: $349.00 per set.

This is slightly over my head. However, it allows you to adjust the camber in the rear of the B13 chassis. Cusco, Ground Control, and Stillen plates are for the front end.

From this thread: B13 Rear Camber Adjustment - SR20 Forum
This product and thread is beyond my limited grasp, however if you consider these aftermarket radius arms you probably know a lot more than I do. This was posted in the "Autocross, Rally, & Road Racing" section of the forum for a reason.
What else can I do to adjust rear camber? This thread answers your question:
