Optimal front sway for a 1.7 ? Options

[Literati914]

I believe, if I’m not mistaken, there was a 13mm front sway bar for the 912 cars.. and I was wondering if that wouldn’t be more appropriate for a 1.7L 914 rather than the stock oem 15mm. I’m not sure if anyone bothers with a ARB on a 1.7L, but the 13mm ones are fairly easy to come by, cause everyone upgrades to bigger. So that’s a plus. Thoughts?

Anti roll bar size has nothing to do with engine size given that for all practical purposes all T4 engines are the same weight and don't fundamentally change the weight distribution of the vehicle.

I see a lot of discusion about adding front bars but almost no one is stating why they want one, what problem they are trying to solve, and what their current setup (spring rates f/r, presense of rear bar & what size, tires, etc.) are.

FWIW - as a generalization, adding a front bar will increase understeer, adding a rear bar will increase oversteer. So how many are really trying to increase understeer?
