I run a sportsmans car and you guys seem to run the same rear setup as we can. I currently run multileafs and works real good on hooked up tracks but the guys with 3 links
and short panhard bars eat us up on the dry
slick tracks. I have everything I need to make the swap. Maybe the only drawback is the c/o eliminators. I have read the posts in
this section and there is some pretty neat info. I am looking for some help in this matter. All help would be appreciated.

BEST SET UP I'VE SEEN IS TO PUT THE RIGHT REAR SPRING ON THE TOP OF THE REAR END WITH A WEIGHT JACK AND A COIL OVER ELIMINATOR ON THE LEFT REAR IN FRONT OF THE REAREND WITH A 700LB. SPRING ON THE PULLBAR, AND RUN ABOUT 75 LBS. OF SPRING SPLIT WHEN IT GETS DRY.

Littleman, can you explain these advantages.
what about panhard bars. I have been considering changing the style and length when we visit tracks with different racing
surfaces than our home track. At home we can
spank everyone on multileafs(rough track)but
I know for a fact we can get quicker with a
link type suspension.

AS FAR AS THE THE PANARD BAR GOES I WOULD KEEP IT AS LONG AS POSSIBLE,TAKES OUT ROLLSTEER.CHECK AFCO WEBSITE ON PANARD BARS VERY GOOD INFO THERE.WHAT KIND OF TIRES ARE YOU ALLOWED TO RUN?HOW TALL AND WIDE ARE THEY?MAKES A BIG DIFFERENCE ON SET-UP.LATER LITTLEMAN

Littleman, we run Hoosier tires, the economy
style. Normal RR size runs around 90 to 91
inches, left rear as needed for the specific
track. We have experimented with a Detroit
Locker in Ford 9 inch but didn't have it in
a good enough chassis to tell if there was
an advantage. Idea being close to no rollout
or none at all. Have you ever heard of anyone
trying such ideas.

MOD RACER 93,YOUR SPRING RATES SOUND RIGHT ON.DON'T BE AFRAID TO ADD CROSS WEIGHT TO HELP OUT THE BITE THIS SET-UP DOESN'T HAVE A LOOSE ON ENTRY PROBLEM.GOOD LUCK

STROKEN3,THE BIGGEST ADVANTAGE WITH A PANARD BAR TO LEAF SPRINGS IS SIDEBITE ,WITH A PANARD BAR YOU CAN LOWER IT DOWN WHEN IT GETS DRY TO GAIN SIDE BITE AND TIGHTEN CORNER ENTRY.WITH LEAF SPRINGS YOUR PRETTY MUCH STUCK WITH THE ROLLCENTER YOU GOT UNLESS YOU ADD LOWERING BLOCKS AT THE TRACK ,BIG PAIN.

Littleman, I have to agree on the leafs, changing the lowering blocks or adding static
cross weight is a pain. I ran a 3 link before
with both c/o eliminators in the rear of the axle and a rubber mounted 3rd link 3/4 the length of the lower links with a j bar left side chassis mounted. It worked great, but I
had to sell it to try latemodel racing(mistake). The leafs on the car now were on it when we bought it but I can't stand them.
Even though the car I sold won about every
night when we showed up with the leaf spring
car it was all over. Most folks can't understand why I want to change. What about the Detroit Locker????

Strokin3 If you say the leafs were on the car when you bought it this may be your problem. They could be wore out, but you hate to buy new ones if you dont like them to start with. If you have the stuff to change to 3 link I would change. I would use the coil, mono-leaf type, that away you could just bolt the mono-leaf in the existing mounts and just make the pull bar mount and eleminator mounts. Our stock class is going to allow this type of setup next year. We run DOT hoosier tires, I usually run 3 to 4 inches of stagger even on dry. The car is so heavy 3275lb. that it is just to tight without it. Dont' know anybody running a Detroit Locker. 9" with mini-spool seems to be the way to go for dirt.
