I had the sway bars installed and currently have the factory stock "sport package". They made an impressive and noticeable difference.
Also, not yet on their website, but Stillen installed their first auto transmission upgrade (shift kit) on a G35 Coupe while I was there having the sway bars installed. I was told it is a "night and day " difference. Approximately $700 - $800 I believe.

 

We've put a couple sets of swaybars on here and they do make a nice difference, even the non adjustable ones make a very noticeable difference.

Stillen's list is $699 on the AT upgrade. It includes stiffer springs, they machine the body to increase line pressure, etc.. I don't have all the details yet, but they are available.
You have to ship them your internals, they work their magic and ship them back. It takes approx 3 days for the work and they can ship back with ground-next day, whatever is necessary.

I unfortunately don't have the Hotchkis bars in yet, so I don't have any driving impressions with them yet. However, if they're anything like their other products I'm sure they'll work very well!

I do vaguely remember the order, that was about 2-3 weeks ago, right? Please let me know how it turns out!
