I've been trying to find definitive info, and can't. Yes, I've searched.

I have '11 G37 Journey sedan non-sport RWD. As you guys know, the sway bars aren't too stiff. So, I am looking at trading up to sport OEM sways, as a budget alternative to getting Hotchkis, which would admittedly be a better albeit more expensive choice.

1. Do G37 coupe sways fit G37 sedans? - all info I was able to find points to YES, but I'd like confirmation.

2. Are OEM sport sways more stiff than OEM non-sport? - YES, but what is the stiffness difference?

3. Are OEM sport end links different from OEM non-sport end-links? - anyone knows?

 

According to this thead:

Hotchkis stiffness specs are:

If I'm reading this right, the front OEM sport vs non-sport have 25% stiffness diff, and rear OEM sport vs non-sport - 115% stiffness diff.

But another set of eyes would be nice.

 

not sure If this helps but found some stiffness % in this thread: https://www.myg37.com/forums/private...sway-bars.html

 

OK, so he says But that info is based on Hotchkis website too. And the rear number sounds a bit off.

 

I got Rochesters' Sport sways from his Sedan and put them on my Journey Sedan a while back. No difference in outside diameter, and while I didn't weight them they feel very similar in weight. Combined w/ my coilovers I notice a slight change in higher speed cornering but not enough that I would recommend getting them. If you're going to upgrade sways I'd go aftermarket.

 

That's what I'm beginning to realize as well...

 

CodeFlux.......if this helps....I have a set of OEM 37S sway bars from my 08. I replaced them with Eibachs on front and rear. I use the car for autocross and I can tell a difference in the OEM vs Eibachs. If you are interested in them...PM me. Otherwise, good luck on the search, this is always a hard thing, at least it was for me. I just dove into the Eibachs and don't regret it at this time.

 

You could always try an AWD front sway, It is larger than the sport OEM and just a few mm smaller than the hotchkiss, and then pair it with the sport rear sway which is the largest of the OEM rear sways. These might pair up well on a budget. (Actually it's what I use along with the cusco ftsb)

This is assuming the research I did on this last summer when I was doing the same thing is correct, so if anyone knows different, please correct me.
