How much of an increase have you noticed in NVH (noise, vibration, harshness) on the interior of the car? I have the hotchkis front sway non adjustable, and the middle set to the least stiff setting and noticed quite a bit of a difference.

 

Not much, if anything at all.

 

I have Hotchkis as well. Set to the middle setting and very little, if at all, VH attributable to the sways.

As far as the N part, I have some other stuff that sorta covers any noise coming from the Hotchkis.

The sways are one of the best mods on my G. They changed how I view the car completely.

You shouldn't get any increase nvh while driving straight. More harshness is expecting when turning. If set too tight you might even get steering wheel kickback.

I have the eibachs in the middle hole in the rear and soft hole in the front (I think, maybe the other way around - it's been 3+ years since I installed).

 

Come to think of it, I might notice a little extra kickback on the steering wheel during a turn if I hit a large bump.

Still love my sways!

 

Ditto here.

 

Eibach sways set full soft front, full stiff rear. No NVH increase.
I do 3 wheel it on my steep complex entrance when I come in at 45 degrees, and if I give it too much gas, the unloaded wheel chirps. So there's some added noise for you.

 

Stillen front and rear.

Front is middle setting, rear is softest. No increase in NVH, make sure to keep them greased if there's a fitting.

When I had the rears set to the stiffest, I'd get wheel hop over bumps if I was in the middle of a turn, but handling was better on the stiffest one.

 

I've had Hotchkis on my car for 5 years now and they do squeak in cold weather, but I haven't reapplied the grease on the bushings in all that time. Hotchkis uses upgraded polyurethane bushings while the eibachs use the stock bushings so they will squeak unless greased occasionally. Both are set to middle on my setup and at times can have a harsh or stiff feel when going up inclines or ramps at certain angles. However, this is without a doubt the best bang for the buck mod for handling.

 

My eibach sway bars came with new poly bushings. I did reuse the bushing brackets.

On the car now for 4 years, no squeaking yet though i'm sure that's a function of what environment the car is driven in.

Sway bars should affect straight-line handling, they only come into play when the car is cornering. If set to stiff, you may get steering wheel kickback if one wheel hits a bump.

 

I get the kickback when I hit bumps! I thought it was something else binding in my steering or a knot on my tire.

 

Edit, meant to say above sway bars SHOULD NOT affect straightline handling. If you're getting steering wheel kick back then set them to softer settings.
