S14 Sway bars

[pndjones]

I have a question about suspension set up. I currently have Stance GR+ Pro on my S14 with stock sway bars. But when I ordered them there was a deal on sway bars and I got a set of Intense Power sway bars for free. They are 30mm in the front and 28mm in the rear. What do you guys think about that set up? Do you think that it would be too stiff in the rear and cause oversteer? What are your opinions on this? If you guys have any input on this let me know. Thanks

I can't speak specifically to the S14 but when I initially built my S13 I put a larger HICAS rear sway bar on it, along with a larger aftermarket front bar and it was drift-o-matic! I couldn't keep the rear end behind me! I went back to a stock bar and got it under control and eventually went with no rear bar. That said, since you have them, the only installation cost is labor so feel free to try it and let us know!

Same here...

I ran Whiteline bars front and rear, for a long, long time. With Eibach springs and Tokicos shocks...then later, with Tein HE's (8k/6k).

I was trying to dial out some oversteer, and finally just put the stock S14 (SE) rear bar back on, in place of the Whiteline bar...and it was a major improvement.

I'd say that 28mm rear bar is a poor choice for roadcourse / auto-x use.

Use the aftermarket front bar, shelve the rear one (i.e., keep the stocker).

From what I've seen on here no one runs anything bigger than the J30 19mm Hollow bar (with the exception of a few). Seems to be a good balance of rear roll control and keeping the back end in check. I can't say from exp as I never had a rear bar (base) and I kind of like it.

Also if you don't have a Different (Even an HLSD IIRC) the thick the bar the easier its gonna be to pick up that inside rear.

Depending on your rear diff, roll center, and spring choices, then that rear bar may be WAY too big, or just right.

With an HLSD and 8k/6k springs on my car, I run a Sus Tech front sway and no rear, and I still have issues with wheelspin coming out of corners on my stock-ish KA. With any rear bar installed, it would pick up the rear enough to cause the inside wheel to spin like mad and I was getting pulled by Miatas on corner exit. (ouch!)

I've pulled Z06s at 15 psi coming out of corners with my 19mm J30 rear bar and a HLSD.

Thanks for the help guys I really appreciate the comments! I will install the front sway bar and leave stock SE bar when I am doing my brakes over the holidays. Hopefully his will help my handling.

I run Progress bars
front set at the second setting
and rear at the lowest
Zeal XS coils set to soft (3 front and 2 rear iirc)
was ambivalent at first at the added steering response
but I've gotten used to it and feels 'normal' now
this was on an open diff too
since I've swapped to a vlsd unit

daily driver btw
car isn't driven hard

all the car needs is to upgrade some bushings
and do some roll center correction on the front and it'll be solid

I too have been debating on changing the rear back back to stock (s14) I didn't like the way it worked without a bar, and I think the current bar is a *smidge* much.

[Def]

You should try a 19 mm J30 bar if you want a hair more than stock S14.

[pndjones]

thanks for all the tips guys!

Are the helper springs on the rear of the GR+ Pros going to be negating some of the effect of whatever bar he's running?

Trying to clarify that since I'm on essentially the same coil-over setup with stock sway bars... And my main goal for the winter is to find some more grip up front.

[Def]

Tender springs are good in the rear. They give you some more usable droop. For more grip up front get some roll center correction, lots of front roll stiffness, and then run tons of negative camber up front (like -3.0 as a minimum, -3.5 is more likely the range you'll end up, maybe a hair more if you run it on track with really sticky tires).

[CodyAce]

Well upon doing some research, it seems as if people have remarked that the double humped J30 bar contacts the fuel tank on the s14. While making spacers seems like a solution, I need to also consider the fact that my subframe essentially contacts the car itself due to trimming the ES bushings down in the back...so I think it may be a fruitless endeavor to say the least.

I guess I could make a spacer for the bar itself, but now I'm really getting wacky...maybe I'll just find the lightest/smallest JDM bar and sell this whiteline.

I thought I remembered Greaser just bolting one up for his VH dual exhaust.
