Limited late - z link option

[Dirtmod13]

Ran 3 practice sessions with the clamped in front of the left rear. Car was really fast. Track owner took away the option to use clamped up. Now Only 2 options are bolted to birdcage ( so it rotates away from the spring in the corner) or z-link. Now i can see how the z- link would rotate into the spring just like a clamped up setup, but is a z- worth trying? Another car there had it and he looked to be quicker than the others. Does anyone still use this setup? What spring?

Call cj rayburn he will talk to you no matter what car you have.

They won't let you put it on the forward arm and run it on swingarm?

We ran a z-link with spring on the swing arm car .It was easy to set up and adjust, had a wide sweet spot.Best i remember had a 400 r/s spring,500 l/s with at least 150lbs of bite.

Coil over must attach to birdcage. No clamp.Must be mounted in front of axle on left rear. Everything else is open. But we have a shock rule so no adjustable or re-valved shocks. Installed zlink tonight and cycled it through. Doesn't rotate a whole lot into spring. But definetly more than the 4 link with spring attached ahead of axle on birdcage on LR. Tried soft spring to get some preload and have spring rate on LR at full drop but even at 125# it has a couple inches of gap between spring and top of coil over cup/ mount. 225# had 4" of gap.

Need really long trailing arm.

Need really long trailing arm.Top / rear , used the longest bar we could find. Wondering about indexing birdcage a little bit differently, wonder if that'll get the wrap into the spring. Wondering about that for the 4 link also. Since its mandated to be in front- it indexes away from the spring. But maybe indexing and maybe moving one or the other closer/ further from the normal mount on points where bars bolt to birdcage we could lessen that negative effect.

The old Rayburn geometry with 32" trailing arm works pretty well for your application.

You could move the lower link closer to the axle and get a lot of angle in it. 20 degrees at least

We added the longer rear bars the second year.The car was very quick on the little bull rings.We could get it to hike the l/r up high if we wanted.It was never any faster like that.

Update. First race, first ever feature win in Usra limited late model class. I appreciate all the help and discussion/ ideas all of you have given to my posts and others as well.I think it was possible only because of things you guys have posted and taking the time to help us guys out. Thank you.

[MasterSbilt_Racer]

Nice of you to let us know. Congrats!

[TheJet-09]

Congrats on your win! Now your competitors are going to be looking at what you're doing.

Congrats on your win! Now your competitors are going to be looking at what you're doing.Right?! So we need to cover the rear end because what we did is so simple if they see it they'll duplicate it. What is the rear cover called and where do u get them. Some are printed.

[Punisher88]

Modern Images can make them for you and if you get him to do your wrap he can even print them to line up with your wrap and match it when on the car. Tell him Russ Ogletree sent you if you contact him.(706) 681-4665

Kind of interested in clamping the left rear like was discussed earlier? Is there a specific bracket you buy to do this and do you remove the traction shock and just clamp the shock with the spring in front of the axle to wrap into the spring when under throttle? Thanks for any info.

Thanks for any info.With my car , it has bolt holes on the inside "clamp" of the birdcage. Just pulled bolts out that held shock mount to birdcage and bolted it from the clamp. Clamp is the closest part to the gear case/ center section. Felt really good on my car. But track wouldn't allow it.

[Punisher88]

So you removed the traction shock and moved that bracket up? Did you do anything on the shock adjustments for rebound or compression. Thanks in advance for the replies.

Are you running @ MTS Fountain City?

[Molson29]

Yes he does run MTS.

[Krooser]

Kinda figured… thanks.
