I did not see any improvement in performance when I took the leafs off of my car and installed coil overs. There was a little weight savings though. It's all about the geometry on the ladder bar set up. Once you find the sweet spot your car will start working

Mike, I thought the slider helped keep the rear from binding. I have a lot of options to sort through. Ladder bar, 4 link, or Cal Tracs.

Re: Spin Control Question

Cal-trac, cheapest , easy to work on, they can walk you through the prosess. There are many Nova's running them, just look at the pictures posted on this site.

If money was a non factor, would Ca'-tracs be your first choice?

Re: Spin Control Question

Yes ! Just look, pictures abound all over the net, many bracket cars and Stockers run them. The reason ? they work. Add them and get your front end to work then hang on !

Re: Spin Control Question

With ladder bars and leaf springs, the rear end housing must be mounted in "floaters" in order for the leaf springs and ladder bars to work without binding.

If you do not have something like this : http://www.competitionengineering.co...?CatCode=10047
on your car, and you're running ladder bars and leaf springs, your rear suspension simply does not work.

Given the choice, I'd never bother with ladder bars again, ever. If I wanted full aftermarket rear suspension, it would be a four link with a wishbone locater and coil over shocks.

For a car like yours, if you do not intend to go faster than 9.30 or so, and you want to run smaller tires, say 9" and 12" slicks, the by all means I'd put a complete Cal Tracs system under it, their leaf springs, their bars, their mounts, and their shocks.

Sure, full aftermarket suspension is the ultimate, if it is allowed, and you're going really quick, it's the thing to have.

But you're running in the mid nines, and you're running 9" tire classes at times. I would not go to the expense of a four link for that.

Re: Spin Control Question

While my race vehicle isn't comparable to yours, what was the same is I had ladder bars installed on mine and was using the Competition Engineering housing floaters which did allow the rear suspension plenty of movement (no binding)....I had issues with control and any track that wasn't perfectly flat the rear of the vehicle would " float around" and actually steer me where ever it wanted.....very unnerving.....after a couple years of this I went to Comps "Slide-a-Links" (similar in theory to "Caltracs").....Night and Day difference, didn't even feel like the same vehicle.....Caltracs Work.....bottom line, put the system in and dial in the rest of your setup and don't look back......

The thing that turned me off to CalTracs was a video of a rear rotating what I thought was a long way on a car with Cal Tracs. Paste this in and have a look. http://flic.kr/p/cfLT6W
Here's another shot from the back. http://www.flickr.com/photos/simpkinsfamily/7387114350/
Isn't that a Cal trac system?
I can't see how my set-up could possibly rotate that much. It looks bad to me

Re: Spin Control Question

Ron, there are big block Chevy cars that weight 3400# going mid nines on 9" tires with the CalTracs setup. It works, there's not a lot more to say.

I have no idea how the car in the video is set up.

On a 9" tire we're carrying the front wheels all the way to high gear consistently with CalTracs and the rest of the setup I described. If we can't hook, no one can. There are big tire cars that will go home if we so much as spin the tires a 1/2 turn.

Re: Spin Control Question

Thanks Alan, I'll call them tomorrow. Hopefully they'll work with the slider box currently on the frame rail. Plus I'll need a couple perches.

Whats the saying....you can lead the horse to water but you cant make him drink....LOL. Out of the 30+ posts in this thread, 15 of them are experienced racers telling you to get rid of the sliders and run all the calvert stuff. Set it up like a stock eliminator car and you wont be dissapointed. Set it up they way they tell you to and you will never ever have a problem.....after 5 years of beating my springs up I went under the car and re adjusted to bars per calverts spec and the car is leaving harder than it was prior to the adjustment. Good luck!!

PS they have a real nice set of perches that I would recomend you but.....way beefier than a moroso mount.
