Does anyone know the sizes of the Stock G35 Sways F/R and the Sport Sways F/R?

I've been looking for this information and I haven't came across it.

Can someone chime in or point me in the right direction?

Thanks,
-Henry

 

no one knows?

 

the size .?? of sway bars ??

both should be similar except aftermarket should be thicker and has adjustable settings ..

bolt off the old one bolt on the new one ...

or what are you talking about .??

 

see if stillen mentions their diameter cause it's the same as the stock one.

 

What's the reason? If you want to check if you have the stock vs after market? AFAIK, all aftermarkets are either adjustable (3-4 holes) or are a diff color.

I think all but a very few oem bars are the same. Coupe/sedan/Z.

 

The reason I wanted to check is because the stock sway bars look exactly as thick as the aftermarket sway bars. So i wanted to see if i would even benefit from bars that are the same size in thickness? The one difference from my sport sway bars and the hotchkis is the hotchkis is adjustable. Will I see a pretty big change in handling with the same thickness bar?

 

thanks guys for the responses....

 

Hotchkis: updated info on 1/3/08, thanks Texasscout
Construction: 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. Includes greasable bushings and brackets. Bars now come with welded retaining rings/collar stops The back bushing have grease zerks on them now. Front bushings still must be removed to be greased.
Bushings: rubber?

Pros/Cons/Experiences/Settings: some people complain about squeaking w/ Hotchkis (but I've read that you should just put more grease on them)
The bars do not incorporate bushing “stops” to locate the bar. Some people have noticed the bar shift to one side or another. The fix is to purchase a pair of “collars” from McMaster Carr (part Number?)

 

simple answer is YES.

even with the same bar same materials same diameter, the
location where it hooks up to the endlink will determine how much
more torque it will take to twist the beam.

 

Our factory sway bars are hollow as are most aftermarket bars. Although the aftermarket bars may be the same diameter they have thicker side walls and different metallurgy and manufacturing processes to create a stiffer bar for the size, plus the adjustability of the multiple holes. Note that some bars are solid, such as 350Evo, Progress, H&R, Whiteline and may be thinner, which has no reflection on stiffness calculation in comparing to stock. There is a sway bar sticky somewhere on here comparing most of them. Also, Hotchkiss bars now have collars built in to prevent side movement and grease fittings.
