my current setup for reference:

10 degree blocks with (rearmost) 6 degree castor
front width increased slightly with 2 brass shims on axles
.020 front spring w/ #3 on the kingpins
angled servo
black 42mm full sauce
1 1/2 degrees camber
0.5 toeout
3.5mm ride height
slight droop (2 shims above eyelet with fresh springs)

Rear
lipo centered in slots
std flex plates in long position w/o set screw
#3 in the tubes
Gold spring w/ 50 wt. oil in the silva shock
medium ballstud +2 brass shims on shock mount 1 step from most aft location (shock is pretty close to 2.95" free length)
yellow rear tire 45mm
1. pod droop
3.5mm ride height
172mm wide
pod level

my current ambition is to search for less scrub on corner entry and more corner speed.
last week i tried inline front axles with the above which made lap times less consistant, and went back to trailing axle.

so the current questions:
1) front tire wear, even with the camber pretty much maxed out (without cutting something) i still get a reverse coning wear pattern on the front tires. with 1/8 scale i was taught to adjust camber to get even wear across the front tires.
is this common for 1/12 scale, or is there some other adjustment i should be chasing?

2) corner speed on carpet strategy(s?)
for 1/12 stock (1s 13.5) i don't see an obvious choice between
a) short tight lines with reduced corner speed
b) straight lines and medium radius corners with some loss of corner speed
b) longer radius corners at higher corner speed.
i am still a carpet newb, but it seems that the carpet sucks so much speed off the car in a turn that i want to take a tighter line to minimize this load on the car, without resorting to too much brake on corner entry.

do fast stock cars run with wide open lines or tighter lines with minimal off throttle, or some other tactic?

thanks for the help, tony.
