Sway bar sizes for 1984 930 ...

All,

I've searched and although there is alot of info on sizes for non-turbos not much on turbo sizes.

My car is a street car with very little DE use, but when I do DE it, the body roll is more than I want. I'm not going to upgrade the shocks/torsion bars (don't want the on street ride stiffness) but my mechanic suggested adding stiffer sway bars to help with the roll but not have much of an impact on street ride stiffness.

He's upgraded alot of NA cars this way and everyone agrees that it's a good combo, but he doesn't have much experience on the turbo sizes needed.

Any thoughts? The front is a 22mm already and the rear is an 18mm.

Should I upgrade evenly? (i.e. up same amount both ends?) Go 22mm both ends? The 1986 turbo went to 20mm in the rear with the front the same supposedly to also help with oversteer although I'm not sure how the rear sway will help with that? but that could just be me

Thanks in advance for help/advice ...

thnx

Berardino

I believe that your stock bars were a 20mm front and and 18 mm rear. Have you already upgraded to the 86-89 front bar?

Regards,

a car with heavy spring rates and proper sway bars will be better on the street than a car with lighter springs and too heavy a sway bar.

Call me or PM me and I'll help you out

I've got 22mm adjustable Weltmeister bars front and rear that came with the car. With stock torsion bars, I had the front sway bars at full soft and the rears at full stiff and I could get rid of most of the understeer.

I've got 22mm/31mm torsion bars now, but I've only driven it this way for a few days and I've been driving it pretty cautiously so I don't have a feel for how the balance is.

I find the stiffer sway bars cause more of rough ride than stiffer springs/torsion bars. Given the choice I'd rather run smaller sway bars and larger torsion bars.
