I just bought/received an H-sport competition rear sway bar from Way on his recommendation. I am getting into autocross but drive the car on the street a lot. For autocross I think I should likely use the middle setting but is that setting okay and good for the street? Will it make the backend a little to lose for the street?

On the softest and the middle setting will there be any risk of the backend sliding out on high speed long straights while on/off the throttle and changing lanes?

 

I have mine on the soft setting, and have not felt the need to go stiffer. On ramps and street driving has not caught me by suprise, even with bumps in the middle of a turn.
Everyone has their preference, so I reccomend starting at the soft setting. It's less than 1/2 hour to adjust it, so try a couple of settings once you get the baseline feell.

Have fun,
Mike

 

Make it STIFF! Mid setting is a good start. You won't have a tail-wag happy back end at that setting. Yes, you can induce a litter oversteer with the right steering inputs and throttle lift. The stiffest setting would be best suited to very tight Auto-X courses. You'll be dog-legging with ease!

 

I run it in the middle setting on my Coupe (NM Springs/Koni Yellows) on the street and find that it works well. No tail chasing for me.

 

Always start with soft on the street. AutoX go soft or mid setting initially and play with tire pressures.

This is how you can test for "neutral" handling. In a big parking lot, mark out an area for a sweeping turn. Then take the same turn going faster and faster at the same sway bar setting to feel for a "loose" back end. Change the setting and test again. Once you feel the back is loose in a constant turn at speed, dial it back one notch. Then you have left yourself some safety margin. This of course assumes you take things in small steps and know what oversteering feels like.

At this setting you can still throttle oversteer or trailing brake oversteer reasonably safety.

When you adjust front camber, you should also adjust the setting on the rear bar to get it back to "neutral".
