Torsion Bar Replacement

Grasshopper said

I appreciate the advice. When I called PST they said that the 1.03 bars were rated for a 440 or 426 Hemi and though they would provide better handling would create a very stiff ride for my 225/6 Samp street car. They went on to say that it might be better to change the sway bar and strut rod bushings. I do want a nice ride as well and trust your advice more so than PST as we drive similar cars. All things considered what size bars should I use for my 225/6 street cat with a/c?

Remember, it's not like the six is any lighter than a small block. They just got wimpy t-bars because the factory assumed the buyers were more interested in comfy ride than performance.

Personally, I think 1.03 is a bit much for an otherwise unmodified street car. You really would want HD rear springs and sway bars with that high a spring rate in front. .870 would be small block HD size, and .890 would be big block size.

I have .890 on my 273 car, which also has HD rear springs, f&r sway bars and KYB shocks. This is a well balanced package. I could probably have gone bigger, but my theory is stiff roll control and moderate springs is best for a daily driver/fun car. Stiff front springs, loose rear springs, and no roll control would not be a great combo, IMHO.
