The weight should be supported on the spindle centerlines to prevent any weight transfer fore or aft. It probably won't make any difference. Let us know if it does.
According to my information, the riding height of the rear of your car is an inch to an inch and a half lower than stock. The IC result I have for your car is:
IC length is 128.9".
IC height is 14.5".
Anti-squat is 55.2".
ya'll working me too hard
...i will do it tomorrow and see if it makes a difference.......thanks BobI had GTA wheels with 245/50/16 tires... Other than that... I think it is all stock....
Your axle housing points are very close to my numbers, so the tire must be close to stock diameter, but the body points range 1" to 1.5" lower than the numbers I have for a stock GN. I'm going to check my stock GN in the garage.
My GN in the garage has a lower front mounting point at 9 5/16". Very close to yours. Using that number with your other figures gives me:
IC length 135".
IC height 14.3".
Anti-squat 52.5%.
Pretty close to your results. When I first read your results in the other thread, I thought it said 10". I just realized it was 10'.
IC length 135".
IC height 14.3".
Anti-squat 52.5%.

What and how much did the lakewood bars move?
Leaving all other points the same, you would need to drop the lower/rear mounting point over 6" to get within the suggested IC box for a 11.0ET. Not very realistic.
I heard 3". That's why I used that number in the other calculation. But if anyone knows the number to be different, please post it.
I don't know how much it moves it.... Ed Brewer was running a set on his old stock motor... stock turbo'd white T years back... went 11.30's... 60' time was like 1.48.... not too bad for a stock turbo'd car....
Maybe KevinS here on the board said he thought the no hop bars moved the IC too much...
A quote off an excellent read IMHO about launching a drag car....
"For the most part, the IC is what is adjusted to get the initial hook and the shocks should be adjusted to maintain the traction throughout the 60'."

On the race car with the Moser axle housing and a 29" diameter tire:
The lower/rear mounting point is 9.81". The lower/front mounting point is 11.56"
The upper/rear mounting point is 20.12". The upper/front is 19.93".
That puts the IC at 87.8" length, 17.9 height, and 97.1% anti-squat.
Lowering the car with different springs 1.3" will give me:
IC length 44.1" ahead of rear axle.
IC height 11.2".
A/S 124.2%.
This is my target for an 8.50 ET. Not sure if I'll be able to lower the car as much as I want due to tire to fender lip interference.
