Sway Bar Diameter

Thinking about re-bushing the Z. On the 90 ZR-1, what are the sway bar diameters front/rear? From what I have been able to find online, I think they are 30mm front / 26mm rear. Is this correct?

Would be interesting to know which it is. Only reason I'd think they might use a bigger bar than the base suspension is to offset the understeer caused by the bigger rear tires and (slightly) stiffer front spring? :dontknow:

Well the front sway bar is larger that the back, so I would say it's 26/24.
