I have the same car, but I have coilovers in the rear. The car is a point A to point A street fun rod.

I just went from 22mm front torsion and 250lbs/in rear to 22mm front and 300lbs/in rear. I have Bilstein Sports in all fours and OEM sway bars.

I think that the 250lbs/in spring rate in the rear was too soft. When I went around corners, I would have to slow down because the inside of the nose was lifting up. When I went to 300lbs/in springs in the rear, the car felt more neutral. I could accelerate thru corners, and the nose was staying more planted.

250lbs/in ~ 29mm torsion bar
300lbs/in ~ 30mm torsion bar

Hence, I have 22mm front and (sorta) 30mm rear. I think it is awesome. Very little body roll and very neutral. Some bumps are tough, but I think I still need to revalve the struts, replace bushings, and raise my spindles to fix that issue.
