Can wheelie bars be attached to the frame AND axle?

Is it ok to attach the upper links on 4 link wheelie bars to the frame and the bottom links to the axle?

Will it bind with the up and down movement of the rear end?

Not really recomended... If the car comes up high enough, it will push up on the back of the body and unload the rear suspension. Best to use the brackets and wheelie bars that attach both bars to the rear end housing.

No, the wheelie bars would not bind the up and down movement of the suspension. Im not even sure the Coupe will pull wheelies, but the bars would be a nice precaution just in case it does.

Heres a old pic of the rear. The red dots indicate where the links would hook up.

If they are ridgid (not split at the end ) how is the suspension going to work??
I looks like you want the bottom on the dif. and top on frame. You have to have a way for things to move. Guess I don't understand..:confused:

They should be mounted to the rear end housing to work correctly... The rear end and the frame move on different roll centers and axis'. I would say not a good plan to mount to a sprung and an unsprung attachment point.

Weld on type to the housing is the best bet IMHO and what I use. :cool:

I agree 100% with Dave. Attach all 4 points to the rear end. back in the 70's & early 80's there were a few bars mounted to the body (frame) only but they were not as effective as rear end mounted bars. I've never seen bars mounted to the body & rear end. Every time the suspension moves the hieght of the bars would change. I don't see how they would be effective. Might even be dangerous. Mine mount to the four link on the bottom outside the shocks & because of chassis clearance issues the top bars mount to the top of the rear end "between" the shocks.

Yup, that's what I meant to say. Solid mounted to the 4 link brackets on the rear end housing.

FYI guys, the wheelie bars are only for the once or twice a year the coupe will be taken down the strip (It may never even hit the 1/4 mile, we might just do one of them dynomometer 1/4 mile passes)

you should not attach the wheelie bars to the frame and also the rear end at the same time, your frame is solid and the rear is floating, when the suspension compresses from hitting a bump or a hard launch the bars will drop at the same speed the shocks are working, and they will smack the ground like a hammer. and also when it smacks the ground the bar will then change its direction and push forward to the front of the car putting unwanted forward presure on the rear end and suspension, these little cars with big slicks are squirley enough at speed without having to deal with a faulty suspension issue. you will either have to extend your shock mount up or down and mount your points to the rear end as pictured. and if those zoomies i see are connected to a motor that warrants the use of them, you will need these bars installed correct. thats my 2 cents for the night. by the way i really like that hot rod, could i see a side shot of it, please!

Thanks for the tips, we'll modify the bars to fit properly... I guess it only takes one mistake (like faulty wheelie bar hookup) to end your cars (or your own) life.

Peiceofpaper, that's a very cool ride. You'll be happier with the rear end only mount. Even if you don't plan to use them it will look more authentic and by the looks of the side shot, you might find yourself usin' 'em more than you think. That's gonna' be a wild lookin' hot rod.

Yup. if you think about it, there is one bolt per bar on the wheelie bars. When you connect the bottom 2 bars to the differental you can move that section up and down like a hinge untill the top section has been mounted. If you mount the top section to the frame rail, they will both act as swivel points.
Because of the angle the upper bars that go to the frame rail would be at, and if you bars happen to touch the ground even once, it will unload all the weight that the chassis is putting on the differential and cause the tires to loose all there grip. This happens because of the upper and lower bar sections trying to seperate the frame from the differential.
