FC OEM rear sway bars?

josh18_2k · 06-10-2009, 07:58 PM

i hate to make a thread for this..
is there a difference among OEM FC rear bars? is TII/vert bar thicker than an NA?

I'm looking for the stiffest of the OEM's

I believe they are but can't say for sure... it's been awhile since I researched it. (I ended up going racing beat sway bars anyways)

WE3RX7 · 06-10-2009, 09:02 PM

I believe they are different. If I'm remembering clearly the SE and Vert models came with a 12mm rear bar and the GXL/T2/GTU had the larger 14.5MM rear bar. I want to say you can verify this with the part numbers for factory replacement bushings for the rear...

The part I cant recall is if it changed at all for S4 to S5....

I believe the s4 the turbo is thicker than n/a, and then when they went to s5 both turbo and n/a are the same. Im not sure if they shrank the turbo to the same as the n/a in s5 or if they beefed up the n/a to the same as the turbo. Thats what i remember. I couldnt for the life of me tell you if the numbers so far posted are correct or not but im gonna just nod and agree so i dont look dumb lol

I believe it's divied up by
4 lug = 12 mm
5 lug = 14 mm

I actually removed my rear bar and so far like it. It pushes a LITTLE but I still need to finish aligning and cornerbalancing before I start playing around with different bars

josh18_2k · 06-10-2009, 11:17 PM

my setup is far from stock. i'm currently without rear bar, and i need a little better turn in. front is adjustable, so i can always add more in if needed.

Max777 · 06-11-2009, 01:45 AM

if you're running coil overs, and other rear end stuff like solid bushings in the control arms, double camber adjusters, etc, then it's actually better w/o a rear swaybar.

Have you considered replacing your rubber control arm pivot bushings with solid ones?

ive got a t2 rear bar for cheap if you need it.

josh18_2k · 06-11-2009, 12:03 PM

i dont have any rubber parts.. its all poly and sperical, adjustable everything.
i had a ST rear bar, then no rear bar. i want something in the middle (OEM)

anyway, i just want to trade my ST bar for a stock thicker one + cash

***TitaniumTT*** · 06-11-2009, 11:56 PM

What's the thickness on the ST bar? Is it adjustable? Comparision to the RB bar? I MAY MAY be interested. I still have a lot to sort out so having a stock TII bar in the mill may be beneficial to me.

josh18_2k · 06-12-2009, 03:51 PM

ST rear bar is not adjustable, and from what i read "its the thickest you can buy"
i dont have calipers, so i could try to measure it but it may not be right.

Flooder · 06-12-2009, 04:15 PM

I took my rear sway bar off and I get somewhat more traction whilst drifting. *shrugs*

If you're that worried about sizes, get a tanabe way bar, its thick as shit.

josh18_2k · 06-15-2009, 12:13 AM

im not looking for a thick bar, i'm looking for a thinner one. i already have an ST bar and its too beefy.
OEM should be just fine

Black91n/a · 06-17-2009, 11:52 PM

According to the factory service manual the bars are as follows:

S4 w/o harder suspension: Front = 22mm, Rear = 13mm
S4 w/ harder suspension: Front = 24mm, Rear = 13mm
S5 w/o harder suspension: Front = 24mm, Rear = 12mm
S5 w/ harder suspension: Front = 24mm, Rear = 14mm

So for the rear it would seem that there are 3 choices: 12mm, 13mm and 14mm.

I'll usually check the FSM for stuff like that, as it's full of useful information.

***TitaniumTT*** · 06-18-2009, 12:31 AM

hrm, I thought there were only 2 different sized, 12 & 13
