Would it be better to run the non AWD version? Since it would be more equivalent to our vehicle?
It all boils down to how you feel when you drive the car and whether you plan on upgrading the front bar if and when it is possible.
Some people may want a smaller bar since they don't want to mess with the front bar (changing the front bar can be a lot of work, 8th gen owners have to drop their subframe) and they feel like the numbers should less offset.
I don't care about the numbers. Typically the front needs to be larger, but I'm working with what parts we have available currently. And besides that I know it feels good regardless of the numbers.
But like I've said in my previous posts, the 20mm rear bar feels great to me and the oversteer that may concern some people is only minimal. The oversteer comes on gradually and you can get a feel for it and adjust your driving.
I've tried to get it into snap oversteer situations and had to try really hard to make it do that. I can only imagine this being a concern if it was wet out and having to do some crazy avoidance maneuver.
I plan on going with a bigger rear sway bar (with solid end links) regardless if I change the front bar or not. If there are no front solutions then I will at least upgrade to the V6 front sway bar.
