Cool - it is pretty fun to tune the sways and actually feel a difference in how the car handles!

Specs:
Front 1 3/8" (35MM) Tubular(Bar Weight 13.5lbs)
4 Position Adjustable
Rear 15/16"(24mm) Tubular(bar weight 5.5lbs)
3 Position Adjustable

Bar Rates:
350Z & 03- 05 G35 Front

Hole 1 = 1525 lbs/in (22% Stiffer than stock)

Hole 2 = 1845 lbs/in (48% Stiffer than stock)

Hole 3 = 2270 lbs/in (82% Stiffer than stock)

Hole 4 = 2855 lbs/in (129% Stiffer than stock)

06 G35 Front

Hole 1 = 1525 lbs/in (5% Softer than stock)

Hole 2 = 1845 lbs/in (15% Stiffer than stock)

Hole 3 = 2270 lbs/in (42% Stiffer than stock)

Hole 4 = 2855 lbs/in (78% Stiffer than stock)

Rear:

Hole 1 = 520 lbs/in (80% Stiffer than stock)

Hole 2 = 655 lbs/in (125% Stiffer than stock)

Hole 3 = 840 lbs/in (185% Stiffer than stock)

This was their old setup:

Front 1 3/8" (35MM) Hollow (Bar Weight 13.5lbs)

- 3 Position Adjustable

- Rate Increase over stock: +9%,+32%,+63%

Rear 15/16"(24mm) Hollow (bar weight 5.5lbs)

- 3 Position Adjustable

- Rate Increase over stock: +54%,+92%,+146%

All G35 and 350Z oem sway bar specs follow a more complicated path then Hotchkis's limited sampling, thus they aren't telling the whole story.

I can specifically fill in the gaps.

Group A

03-04 350Z all trim levels (car's without the revised suspension ONLY)
03-06 G35 coupe (all USDM production with oem 17 and 18" wheels)
03-04 G35 sedan (sport and non sport suspension's
All group A car's have the following oem sway bar specs
34mm front 21mm rear
hollow wall construction 5mm in thickness (courtesy of tomsn16)
Torsional rigidity Front: 1130lbs Rear:385 (courtesy BJ EVO350)

Group B

04.5-06 350Z all trim levels (car's with the revised suspension)
05-06 G35 coupe (all USDM production with oem 19" wheels)
04-06 G35 sedan (sport and non sport suspensions)

34mm front 21mm rear
hollow wall construction 7mm front (courtesty tomsn16) 5mm rear
net change in front bar strength from 2mm increase in wall thickness
+17% (courtesty of tomsn16)
