Best sway bar for autocross.

If you run race tires definitely the Hotchkis. If you run in the street tire classes then the Eibach/Stillen might be the best compromise.

:iagree:

Chris, do you know if the Hotchkis front bar is available on its own or do you have the buy both?

OP, you might want to check the toe setting up front. My Z was toed out from the factory causing it to be a handful on course. Just fixing that alone made a noticeable difference.

You have to buy the Hotchkis as a set unfortunately.

The Stillen/Eibach you could get individually at one time, you would have to check to make sure that is still the case.

Forgot that the Whiteline is also available now and can be sold separately, so that is definitely up top of the list for a street tire setup.

Thanks Chris. I was hoping to the Hotchkis came separately so I could replace my eibach front bar now that I'm on A6's.

You can buy the front bar only from Hotchkis....

Right now I'm running Hotchkis Front bar only as my street tires suck. (Bridgestone RE760's) The front sway bar with stock rear bar feels amazing in cornering. When I had the rear on, even at softest setting, the rear was still way to stiff for the RE760's to hold at all so I was getting a lot of instant breaking traction instead of slow and controllable. Swapping back to the stock rear made a world of difference even though I have more roll now. I'm also running the Powertrix R/T Coilover set up and plain and simple, the hotchkis rear is super stiff! Even on soft. I'll be trying out my rear bar again once I switch to the new BFG Rivals when they drop.

Weird to me that everyone thinks the Hotchkiss are the stiffest there are for this car.. The Whitelines are, by far, the stiffest (retail) bars there are for the 370Z. They're larger than the Hotchkiss and they're solid, rather than tubular. So yes there's some unsprung weight added, but the stiffness is insane.

You might not want them with street tires I guess? But if you're going to run an R-Comp and want the stiffest, get the Whitelines.

I love my hotchkis sways. I haven't noticed any additional understeer. They're all almost close enough in performance to buy based on price IMO.

I use a hotchkis front on my unruly car....with no rear bar. That said, the car also has a whole lot of spring.

The Hotchkis does introduce some lower speed understeer on street tires (attacking sharp corners at < 40 mph for example). Camber corrects the issue but unfortunately you can't do that in stock class for our cars.

Can I ask why? Your advice on autox has been great, I just wanted to know what advantages the Whiteline provides over the Eibach?

And is this just on stock springs and shocks that you recommend it, or with something more aggressive?

Yes I'm making the assumption of stock suspension for most amateurs. The Whiteline is somewhere inbetween the Eibach and the Hotchkis in terms of stiffness (both the Whiteline and the Eibach are adjustable). For a street tire stock suspension setup that is about as stiff as you would want to go. On race tires you'll want to go bigger, since there is more traction there is more weight transfer.
