we run the sportaman/streetstock class 85 monte carlo stock sportsman on a well known track in the florida panhandle and we have 15% banks on rough track surface. received this car with 900rf 800lf 1 1/4 bar set at 1" rear springs are 175lr 150rr and car has pushed ever since we raised it up to legal ride height. 52% left side weight. best we can get with low car is 47.5 rear weight. added spring rubber in right front and driver was able to enter with more steering but car still pushes. Just got done doing all of the math for roll couple percent @ 86% front Overturning weight is 530 lbs. total roughly. don't know if this is enough info to get some tips. Just did the math on banking downforce corecction and found out that new wheel rate is 404 for rF FIGUrED IT OUT TO BE a 1200 lb. spring. any help would be awesome. Been off the track fr 2 months because of push and wasting sponsor money. not a guru but i have a few equations i've worked out in the past few weeks. please let me know if you have an equation or formula to get in the ball park with rear springs. haven't found anything on that subject or specific function. also wondering if 400 lb. wheel rate equals out to a 1200 lb. spring on this track. that is with banking down force added.

HEY DUDE
this is pretty simple to me. you need more RR spring.try 250 lb. I bet it will fix it

Downfoce my skinny but! Bring that thing over here, and I'll get you close. What are tire temps after clean run? Pokey has my contact info. Seriously, Frank
