QUESTION
1:
I have a 3100-lb nitrous-powered big block Camaro. Motor is in stock
location. It has 10.5 wide tires. It has run a best of 8.48 at 160
mph with a 1.25 60-ft. When the track hooks good, the car will 60-ft
that, but when it's slick out it spins bad and runs like a 1.34 60-ft.
It seems like if the car pulls a good wheelie, it 60-ft fast and
if it barely pulls the front wheels, it spins and the 60-ft goes away.
When the front wheels do come down it seems to unload the rear tires
slightly.
Is there anything I can do to help that out? My ladder bars are currently
set uphill 3 to 4 degrees. Where would you suggest me setting them?
Also, it seems like I have to run a lower tire pressure than most
people to hook well (7.5psi) What tire pressure do you recommend to
my application?
Thanks.

Cliff:
I would try to run your ladder bars down lower in the front and
reset your pinion angle. You need to scale the car and make sure the
rear weight is 50% with driver in the car at ride height. Once you
are set up this way, you should be able to run more air in the rear
tires.
QUESTION 2:
You said earlier that most of the ladder bar set-ups run a diagonal
link or a wishbone. I am running a panhard bar. Is this right or wrong?
I would like to know what you think about this.
Thank you,
Richard Kilgore
Richard:
Panhard bars have an arch that they travel through. As the suspension
travels, your rear suspension moves slightly side to side throughout
the travel. I recommend diagonal links for ladder bar systems as they
don't have this arch to travel through.
