Ok here is the deal. There is this guy that races here locally in an A-mod. NEVER raced anything in his life now he jumps in with the big boys and is being a "factor" in a lot of races due to him being the only lap car and taking people out. I run a 360, 2 link limited mod and I want to try and help him out. Not sure of the car because it's from south dakota but I was wondering what kind of percentages, bar angles, pinion angle and stuff to start with for him. Stagger as well. He also has what replaced my J-bar but mounts to the frame...not sure what it is called. The car wieghs 2625 and i was thinking along the lines of 54% rear wieght with 110lbs LR bite. what spring rates should he be running in all the corners. We race at a semi-banked 3/8 track. The big thing I am worried about it the car angles on the 4/z link. ANY help would be much appreciated. THANKS!!!

i run a dw8 dirtworks and heres what works for us.
550lf 650 rf 225lr behind axle on the birdcage and a 180 in front of the rr on the birdcage
we run a 600-1200 progressive pullbar at 15* angle and ano 90/10 shock at all

weights are 53 left, 57 rear and 47.5 cross
with 30 lbs of bite all without the driver
1.5 " stagger rear and none in front with 1/8" toe out
we run a semi banked 1/3 mile oval on clay

bar angle should start at 0 degrees lrl
15 degrees lru
on the z link lower at 10* up to front and upper 5-10* down to front or level
this should put you in the ballpark, if its tight trail the rr about 1/2" if its loose in the corner then lower the front of you lower link a bit on the rr.
