The stiffness of them isn't the issue. Honestly I noticed precious little difference between them and the .96 bars I just put in instead. The problem is the way they are clocked. The hexes on each end match, but on all other torsion bars they are clocked offset. Because of this, if you put the PST 1.003 bars in the way you would normally put any torsion bar in, the nose of the car will be jacked to the sky like a straight axle gasser, the upper control arm bump stops have to be removed, and you have no suspension, effectively. The angle it places the lower control arms at is too steep for there to be enough leverage to allow the suspension to actually work.
Now, according to PST, the way those bars are supposed to go in is with the adjustment bolt completely bottomed out, all the way in, which still ends up slamming the nose of the car into the weeds. I realize people like their cars lowered (I don't, I think it looks beyond awful), but those bars make it so low it is unreal. I cannot believe they are selling this product.
The worst part is, mine got scratched up, so they wouldn't take them back. And, absolutely nowhere on their site or their catalog does it say those bars will lower your car. It is apparently just a big surprise. When I spoke to them about it, they told me they were looking into finally putting that on their website, since other people have been complaining about the same exact thing. Had they been responsible merchants, and stated that the bars would insanely lower the car with no other option, I would never have bought them. I hate lowered cars. Instead, I got reemed.
They sent the bars back to me, with a 20 dollar gift certificate.
Anyone want to lower their B body to the extreme? I got some torsion bars I can sell you, real cheap.
