Front Sway Bar

I have the OS Giken Super Lock Lsd and Hoosier slicks (not R compounds, full slicks), and no way would I run a bigger front bar. A bigger bar turns compression on the outside tire into lift on the inside, it's physics, and that is the last thing you want with FWD. Whatever you are gaining on corner entry with that big front bar you are more than giving up from the center-off the turn.

The car may feel better on entry with a big bar, more stable, but testing back to back with data will show lower apex speed and delayed acceleration - even with an LSD. Our first car had the Kazz LSD and we would still get inside tire spin with the sedan bar. A big front bar also starts to take away braking force if you are trying to trail brake, as the weight transfers and starts picking up that inside tire.

Typically big bars are a bandaid for inadequate springs and shocks.

Hmmm i see i see well that is a good point as i have pretty soft springs in the tein s techs and bilstein shocks thry really arent that stiff, i guess if i had coil overs with better springs i would not do big front bar, i do like the ride quality of the tein spring and bilstein shock combo as this is my daily driver, i try to keep it as a true street car, but once i do coil overs i might end up pulling the cusco bar off, who knows!

Sorry if this off topic, but has anyone else done this? I felt like it reduced my under steer, but I think it hits my muffler, not sure about the gas tank. I’ll see if I can stick a GoPro under there and go for a drive to find out.

Yes. there is a whole thread dedicated to it.

You are lucky, some of our cars don't have that nut inside the frame to accept the bolt. I am considering drilling a hole in the back side to place one there.
