View Full Version : help with mid turn push
08-13-2010, 08:49 AM
our early 70's Camaro Hobby is hooking up great in the Heat Races (tacky) - won the last 3... but has a bad mid turn push when the track drys out (like asphalt)
medium to high banked 1/3mile track
53% left 52% rear 49 % cross
(when I shift the rim back space and spacer on ther rear
the cross goes up to 50 %)
2" front and rear stagger
ride hight 5 lf - 5.5 lf - 7 lr - 7.5 rr
easy up on right front and hold down on left rear
2" offset rims on right front and 2"left rear with 1/2" spcr
3" offset rim on left fron and right rear
lf 900# rf 1000#
lr 225 rr 200
my question is should I shift the rear wheels to the right to loosen , if so how far?

i would try swapping the rear spings put the 225 on the right,

You did'nt mention the entry. Put a 3 off on the RF and if you need it a bit more loose go to a 850 LF spring if the track is smooth enough.

would it be better to move the rf wheel closer to the frame or farther away?

how much left rear weight does the car have? what are the shock rates? are your leaf springs wore out and flat? spring rates and pecentages look good for a camaro, i would look else where for the problem.

go straight up on your front stagger, will free the car in the center, but may tighten it on entry. May need another adjustment to free the car on entry.

You have to much cross weight! The right front is over heating in the slick and giving out! You could stiffen rr spring also if you wish.

my question is, are you still on the gas, braking, or rolling back into the throttle when you get this push? seems like taking the tie down shock off the left rear of the car might help, depending on what you're doing when you get this push.
you may not be allowing enough weight to transfer to that rf for it to get enough traction for it to hold onto the track so it just shears the contact patch and away you go. let us know what you're doing with the car when it starts to push.

moved 50lbs weight from right rear to high left and increased right front right side air pressure to 28lbs (was at 20) seems to have helped this weekend... but I beleve it was the driver comming into the turn to straight and not letting the car roll... that was most of the problem - thanks for everyones help.... i'll let you know how it does next race

what kinda tires you run ? 28 psi sounds very high i only run about 14 on right side and 10 to 12 left. on street tires

these were my tire temps:
lf= 112,115,121 rf= 118,111,115
lr= 114,114,122 rr= 134,130,137
it looks like I also have to adjust my camber a little and add
more left side %
