We rent the track today to try our new car. The track was not prepared, very poor traction. At first the wheels where spining and the car cearly headed towards the right, but then it went straight. It has a competition 4 link kit. Any advace please
Thank you

Good starting point is neutral preload and scale the car,you want 30 to 50pounds heaverier on the right rear tire.If your not turn the right upper bar one flat(nut adjuster) at a time for preload till you get the weight there.From there it's adjust as needed for handling and track conditions. I wouldn't make a bunch of adjustment based on one bad pass.If the car repeatedly drives right in either lane on multipal passes then add a little preload in the upper right bar as needed.

Thanks for the info I will borrow the scales and then put the driver inside and go for the 30 to 50 heavier on the right

We tune with shocks for weight transfer,hook and hit.Driving right or left we use preload.

Which of the holes will provide the best traction in a track with poor traction?
I've set mine where the two x's are

Plot out the holes and start about 45" out and 6" up
... you may need to move outward to about 55"... each
car is some what trial and error but thats a starting
point

It was already at 45 but it was low about 2 inches, so I'm going to try to move outwards at 55 and go 6 or 7 inches up
thank you

What do you think of this weight distribution:
56 front, 44 rear is it ok?
or is it better to add weight to get 50 50?

Are you sure you have 117" wheel base? If that is a stock wheelbase barracuda, I would bet it's not. I usually go 1/2 wheelbase about 3 inches high to start.

No, It's not for my Barracuda. I'm working on a 1953 Studebaker with 512 Mopar 727- 8 3/4
