I know that building the front end perfect might take some hand fitting... like the arms, ect. The 12th scale thread is the best place to get imfo on setting up the cars right.

1/12th scale cars are difficult at best even on prepared tracks.

Try some or all of these:

.063 T bar
No center screw in the rear of the T bar
20wt oil in shock
olive shock spring
very light grease on the dampener discs - (you want the weight to transfer to the outside in the corners)
24 front springs
As much castor as you can get. (all of the white caster shims in the rear)
use the 5 degree reactive caster blocks or even the 0 degree
Soak the rear tires and then rub the traction compound into the tires.
Soak the rears again after about 20 mins.
After the second soak, coat rear tires with Coppertone SPF 25 suntan lotion
do not put anything on the front tires - (maybe just clean them)
add some toe in - (toe out will make the car turn in hard)
Make sure you have maximum track in the rear
Make sure the diff is very smooth
Loosen the diff slightly.
go to a 19T or stock motor until you get it figured out
try some 2 stage Jaco pink rears
If you can get some blue front tires, try those
Large diameter rear tires and small diameter front tires (the larger the tire, the more grip)

Nothing is more frustrating than trying to get an extremely over powered car to hook up on the track and the power to weight ratio in a 1/12th scale is very extreme.

Go to the 1/12th thread and start reading. You will get it figured out.
