torsion bars?
hi, i am wondering if i could use the torsion bars from my s10 front suspension on a locost?
it will have a 4.3 liter chevy v6 and the chassis is going to be built by the mcsorley +4 plans.
if they can be used, how should i build the wishbones to work with them?
Thanks
Dave

Only problem is that once installed you have little or no flexibility in changing spring rates. You will also have to look at where you will move the
stresses in the chassis to. Is there much financial benefit over coil-overs?

Certainly the most effective way of reducing unsprung weight/mass but the detail design and sizing of the bar has hidden pit falls also a very high
standard of finish is required on the bar and spline to prevent premature failure.
It might be worth looking at the compound torsion bars on some Honda models such as the late 80s Civc/Ballade/Rover213.

Brings back vague memories (very early eighties, maybe late seventies?) of my mum's Talbot Horizon, stranded 3 times after breaking torsion bars
on dips in the road!!

Torsion bars really need careful design of the ends + good standard of finish + shot peening.
Morris tried getting away with shot peening on the early Minors but had to go back to Issigonis original requirement for it. They made the same
mistake with the Marina.
The Horizion bars gave a lot trouble after Chrysler/Talbot switched production to the Spainish plant --- Ryton/Linwood/Poissy took a lot of the blame
for the quality problems in the Chrysler (Spain) plant. In contrast the Alpine and Simca 1100 ranges rarely broke torsion bars.

Look a E-type Jaguar front suspension :
double wishbones with longitudinal torsion bars

What year is your s-10 Dave? I'd swear my wife's '92 has coilsprings in front -- I'll have to tuck my head underneath to
check...
Cheers, Ted

mine is and old 1985. i originally bought it to build an offroad truck, but then i saw a 7 ,and my mind was almost instantly changed. i plan to use
the engine,trans,rear axle, and as many other parts as i can from it.
