    Torsion Bar Ideas

    I have stock torsion bars in my '64 A body right now, with no sway bars. I'm keeping it small block, and desperately need to upgrade the handling. What are the largest ( or best suited ) torsion bars to use for city driving and a little stop-light tag? I was thinking about using the .920, but was worried it might be overkill. What about the .890? Mancini sells even larger 1.090, but I think they're appropriate for drag racing and non- street driving only. Ideas? Also, I keep hearing that I don't want a rear sway bar. Mopar Performance Parts offers torsion bars for "A", "B", and "E" body cars in a variety of diameters for restorations, performance and racing. Improve the suspension performance and increase cornering ability or weight transfer of your vehicle with these Mopar Performance Parts torsion bar sets. The "A" body bars are 35.7" long; the "B" and "E" body bars are 41" long. Thaes sets bolt right in to stock locations without modifications. (sold as sets)

    Re: Torsion Bar Ideas

    I'm running the 890 bars in a 65 Cuda. I have a 1 1/8 front Adcco sway bar and a helwig 1' rear. I run Koni's all round, although I havn't run the car with the rear sway bar yet, it handled great with out it. Since the last time I drove the car I have moved the rear spring in, so I thought I would have more of a need for a rear sway bar now. I was running 225 50r16's front and 245 50 16's rear. My car has a 360 with a 4sp in it.
    It did get a little rough on poor pavement but overall I wouldn't change a thing, maybe I would even run the 920 bars!

    The .990" bars would be my choice with a 1" front sway bar and 3/4" rear bar. Good shocks and rear springs will round out the package. Subframe connectors will also help quite a bit.

    I've heard about the .990 bars, but who sells those? That's everything Mancini listed for A bodies up there. I rebuilt the front end with the PST rubber kit, and threw on the cheapie KYB shocks ( the car came with no rear shocks and rusted together originals in the front ). Should I just plan on tossing the KYBs pretty soon?

    those 1"+ torsion bars are VERY stiff. I wouldnt recommend those for a street ride unless youre looking at doing alot of hardcore autocrossing and dont mind shaking your teeth out.

    With everyone's input, I'm really considering the .920 or .990 torsion bars. I want to do some street racing, but I want to be able to cruise around without a jerky ride. Right now, the car handles like a turd even with the new rubber and shocks.

    The .990" bars that were in my son's Barracuda were MP parts. The ride was not bad. I haven't driven it with the 1.14s it has now, but he said they aren't bad and he's got KYBs which some people say are objectionably stiff. Maybe it's because he's never had a soft daily driver.

    Re: Torsion Bar Ideas

    i would recommend the .990 bars, i have them and they dramatically improve the handling and are very tolerable on the street, driving down the road is fine, only problem is areas in the roads that were repaired 5 or so years ago, just hits a little harder, but its fine

    a 1 or 1 1/8 bar in the front would be a great addition and shocks would be even better,

    I have the .920 bars with IAC shocks and a 1" bar on my 68 Barracuda, the ride is firm but not harsh. I have 255/50-17's all around and it sticks good, frankly I don't have a rear bar and won't until I get subframe connectors and reinforce the chassis. There is some nasty trailing throttle oversteer and chassis flex now. Since the .990 bars are not avalible anymore-I've seached any listed on websites have been N.A. in the RW. HTH, STeve

    Re: Torsion Bar Ideas

    Our daily driver has the .920- torsion bars, Addco 1 1/8" Front sway bars, gas shocks up front, Air shocks out back. Also a set of the 2" X 3" welded frame stiffeners. It handles better than I expected... and while it's no Porsche, or even close to the handling of my '92 Camaro (on KYB shocks) our Dart does quite well for what it is on the street.

    We ran it for about 6 months without a sway bar, but when we put that in, it made a noticeable difference in handling.

    Re: Torsion Bar Ideas

    I'm not trying to talk trash, but from my recollection, 5.0s handle pretty damn well and '92 Camaros handle like crap. When I was in high school, I got to drive plenty of my friends' Mustangs and Camaros. I'm really thinking about the .990 bars, but now I'm hearing that they're no longer available. ? ?
