Triangulated 4 link and sway bar

[Barnburner]

I have a Ridetech triangulated 4 link on my car. A few manufacturers that I have spoken to did not suggest adding a sway bar. I am in the building stage and, if I am going to run one, now would be the time to install it. What is the general concensus? The car will be used for the typical applications: street use, auto-x, and occasional track day.

If you are going to use a nominal tire size in the oem wheelwelss [like a 275mm rear tire] dont use the rear swaybar. If you are going to enlarge the rear wheelwelss and use a 315mm or larger rear tire, install the rear swaybar. Ours bolts in at any time.

Bret I am at the same spot in my build. Care to explain a little deeper on the "why" for us?

Thanks! I am running 335's in the rear. I wanted to make that decision before I built the exhaust and installed the floors.
I will order one up!!
Thanks for helping spend my money!!

From what I've read in my countless internet hours, putting a stiffer rear sway on will tighten up the rear and will normally cause under steer. And while I'm not 100% sure I'd assume the need for a rear bar while running wider tires would be for compensating spring rate?

Understeer can be quite fun. It's just that all other parts of the suspension (in terms of proper spring rate, shock valving, and axle location) should be taken care of before adding a rear sway bar. I feared it for years (crash-reinforced), but eventually added one anyway; I'm still somewhat on the fence, but my car seems to recover from light rear tires very quickly and easily. I just got some sticky tires to add to the mix...
