Cool; I assume / bet most if not all sway bars are that close to each other anyways (they kind of have to be lol)
As far as Racing Beat "testing" goes; I seriously it was tested that much. Let me clarify; absolutely they were tested, but not to the same effect that someone like
and I are looking for / aiming for.
I absolutely guarantee that it keeps the car flat as my hotchkis did or somewhere nearabouts, which is probably okay for when you get sick on some mountain or curvy roads, but enough evidence has come up to support that the weakest or no bar is probably best for our car.
Again going back to how your car is set up, yes a rear sway can 100% ABSOLUTELY cause oversteer, which is probably dangerous for.. 95% of the people on these 3 forums, especially if you don't know what to do in said situation. Enough accidents happen a day. If you know you aren't that great of a driver; don't tempt it, it's simple as that. When I do mountain runs with my locals I know who the good and bad drivers are, and try to keep people away from those; some thing can happen on a trackday, where someone spins around, you may not see them until the next corner, and the worst that can happen there is you don't see them in time to brake or avoid them.
The problem with adding any front bar is it's decreasing grip.. no matter how you see it, that's what it does, and I proved that very quickly when I disconnected my hotchkis bar and went for a drive.
Now you have to keep in mind vehicle height also has a major major major factor in how our cars handle, also recently proven quite well with my changes again.
Anything lower than Prokit (and I still think even the prokit), is damaging to the car's handling, where it feels like you're increasing the amount of roll the front receives, but that isn't the case, the movement of the arms are absolutely still there, you just receive the feeling differently in the cabin.
So despite whatever RB "tested" (seriously I have nothing against them, but we don't know what they were looking for, but it's clear it wasn't increased grip), chances are it isn't helping the way you think it is, not performance wise.
And likely, all they tested was that it actually fit.. like most other companies that would rather spend most of their efforts on making a product they can sell and make sure it actually fits, vs a true testing and wasting money before throwing it on the market.
