Again, to each their own. My setup has got me to a 1st place National Tour twice, but then again, my driving style is a bit different. I don't even left foot brake. Quote:

Swaybars in general are a crutch for a poorly tuned suspension. That said, you are limited in HS with the mods you can do, and one of them wont be fixing the lack of spring rate, so you do what you can. In a fwd car the last thing I want to do is remove front grip, and that is what a bigger front bar is doing. I would go the other way and find a way to transfer as much grip from the rear of the car to the front. Go with a bigger rear bar, or get a set of proper rear shocks that will help suck up that back tire quicker, forcing grip to the front. In our car we dont even run a rear bar, just droop limiters in the rear shocks that pick the back tire up almost instantly.

Replace the top mount with a proper bearing plate first, otherwise you are just burning money.

^^^This^^^
What I was trying to say, but much better worded and technical.

Yes the F bar loses grip by transferring weight to the rear, but it also gains grip by almost doubling the contact patch of the inside F tire (and gains a little outside F contact patch due to reduced pressures). Is this enough to net more F grip over all? No idea, but it sure feels like it. If I had the tire-curve, I could do a bunch of measurements and math to figure out which gains more grip (on paper). In practice, it would take a serious test and tune session to confirm one way or the other. Again, this pretty much only applies to HS cars and maybe only over-tired HS cars. It's possible it needs R-comps to see gains, and maybe this winter running my street/wet tires will show the front bar to be detrimental. |

I was sold by seeing the car on course from outside, photographs, experienced co-drivers' opinions (after they have driven the car), my understanding of suspension design, and that the car feels faster through many sections on course. More rubber with less dynamic load, or less rubber with more dynamic load: Unless someone does a test and tune (or some serious engineering) of both setups there is no way to confirm which nets more grip, in more situations, on this setup.

Just another idea, but like you stated above. No way to really find out without some serious tests, and proper math.
