swaybar selection

[EJ20]

Hi all,

I just need a help selecting a good sway bar set (f/r) for my BRZ.
For now my setup is tein flex z, rpf1 17x9 and yoko's ad08r (245/45 all four)

I like this setup very nice for daily driven car and smooth. It did improve my times at the track so much better but wanna get better cornering too. So I plan to upgrade my sway bars. I have searched and most recommend adjustable sways.

So I'm torn between to setups, all WL and all adjust I guess.
1 is 22f/18r
2 is 20f/16r

What you guys think? Mine is 90% street car and 10% track days (about 7 or 8 times a year, and each day is three 20 min season (sp?))

Any other quality option?

Thanks

Btw. For now my car is NA but at the end of this year will go FI aiming for 270whp

I have the 22mm whiteline adjustable front stock rear. Fortune 500 coils 6k/7k 2.5 front camber 2.0rear and I autocross. Don't think I need rears, but I haven't been in a track.

What exactly are you trying to improve with the sway bars? That will dictate which ones to get, not just a general guess from people online.

Why are you running 245/45 instead of 245/40? That's an inch taller than the OEM tire diameter.

I run 45 because its more confort for city roads ( too many cracks and holes) I wanted 40 but that will make me suffer for ride quality on daily basis.

Actually I want sway bar to reduce body run. I didnt had issues with that with stock tires and it had a great balance. I wanted to get that feeling again with the new tire setup.

My aim is to get better lap times against other friends while keeping the car perfect steering respones.

You don't need a sway bar setup to achieve this goal. Just FYI.

Ummm then why some upgrade them? I mean if its reducing body roll, whould that make it easier for the driver to push his/her car more at corners?

I think he may have been insinuating driver mod.

1. Misinformation, marketing, peer pressure, a few buy them to fix a specific problem, typically it is advised to change one sway bar at a time to adjust the balance of the car.
2. Reduced body roll does not mean more grip or faster lap times. It may give some drivers confidence, but it is generally noted that stiffer swaybars actually mean less grip is available over a road.

Stiffer does not mean faster.

It sounds like you have tires that are too grippy for your suspension, ideally you would be searching for stiffer springs and dampers to match, at 6kg/mm on average most people would say that's barely stiff enough to handle the tire you chose, most are closer to 7-8kg/mm with a few reccommending as high as 10kg/mm.

Buying new springs and taking a guess and hoping they work out is likely not a good option, buying a new coilover set is also likely not an option you want to pursue so: swaybars to compensate for the lack of spring rate. It's not ideal from what we know about maximizing cars performance, but you're the owner and the best way to learn is to try, swaybars aren't that expensive.

Get the bigger ones, you'll feel more of a difference, you can always take them off later if you want to. Other reputable options would be Perrin and Eibach. Since you don't want to change the balance of the car change both swaybars however Whiteline, Perrin, or Eibach pair them. Someday you may be able to mix and match and intelligently change the handling of the car, but that day is not today for you. Some people run a Whiteline big bar and a Perrin small bar or an Eibach big rear, the options are endless.

I own the 20mm front Whiteline swaybar and it does what I want it to do and the endlinks are nice to have but they are not easy to adjust. It is barely noticeable on the street so comfort is not compromised.

Car parts are not like computer parts, especially when it comes to suspension, the A is not always better than the B despite what the marketing says.

You noticed more body roll when you increased the size of your tires, yes?

+1 ^^^ The force is strong with this one.

hows your oversteer. i have the same coils but with 7k/8k and i oversteer like crazy. thinking about getting the 22mm whiteline front swaybar to dial it out. also autocross...

Only oversteers when I push to hard in a long sweeper.... which really means I'm pushing the limits of the suspension and tires too hard. Right now the tire suspension combo is well balanced.

We had a test and tune, I got pretty consistent and found that on the stiffest setting I was fastest. Your stiffer springs will probably have a different result

Sway bars are for fine tuning the front/rear balance of the car, not for reducing body roll; that is the job of the springs. I can guarantee with 99% confidence that you will not see better lap times by simply going with stiffer sway bars.
