Running some back to back tests on astro yesterday I feel the 1 degree alloy rear blocks from the TC02C give better side bite and a much better feel to the car. To use these on the kit wishbones you will need to enlarge the hole in the wishbone to accept the larger pivot pin. I don't feel that this will weaken the wishbone significantly for normal driving conditions but obviously in a heavy impact it could fail. You can of course use the 2wd wishbones but this will shorten the wheelbase considerably and in my opinion makes the car more unstable.
Try it and see if it suits
