coil over shocks vs. torsion bars - which one?

[doozer]

I am trying to decide between a complete coil over kit or stiffer torsion bars and adjustable spring plates - this is going on an 84 911...

Any advice as to which is a better idea and why..

Any reinforcements needed for the coil overs?

Thanks!

Unless this is going to be a serious track car and you need spring rates higher than torsion bars can give you, or the ability to quickly change spring rates, I would stick with the torsion bars. It's very much more $$$ for the coilover kits. I wouldn't install them without reinforcing the shock perches, either.

Doesn't an '84 come stock with adjustable spring plates?

Thanks ttweed,

Yes - but I was thinking of adding the quick adjust ones with the alen screw height adjust.

The car is too heavy for coilovers without reinforcement to the chassis.lt works okay on a stripped tub but the body is not designed for the amount of forces put on the shock towers by coilovers.l`ve got an 84 also and l considered the coilover route,briefly,but went with the well documented upgrades of heavier t/bars,sways,bushings,adjust spring plates,sport shocks,bump steer,strut brace,etc. The car handles as expected,great.
