Sway Bar Diameter - ZR-1 Net Registry Forums

Scrrem · 04-22-2011

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?

Those are the Z51 sizes.

I'll have to go out and mike the rear, mines probably original.

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?

I'll take a rough measurement today, see of the front matches the back diameter.

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