Front Sway Bar
Anyone have information pertaining to diameter of front sway bar on 2010 Sedan versus Hatch Back? Are they interchangeable?
Thanks in Advance! |

My assumption is yes, but I’m not entirely sure. Are you hoping the sedan has thicker front sway bar than the hatch to upgrade? I bought an xD front sway bar for $50 to up grade mine, it involves dropping the subframe which will be a PITA. And most likely have to steering coupling from the rack and pinion. Most argue just put a sway bar in the rear. Me on the other hand just moved the rear axle frame mounting points to the upper holes and oh man it feels much better.

I have a Sedan, and I has hoping the HB sway bar was thicker for an upgrade. It never occurred to check on a xD front sway bar. Anyone have diameters available for all three front bars?

Spend your money on a rear swaybar instead. Don't bother with changing the front one.

Yeah, I spent a little time looking around the Forum after I asked.
Everyone pretty much made the same recommendation. TRD rear bar is ordered, should be here soon! Thanks! |

i have the cusco front sway bar with the trd rear swau bar, i will say in my opinion a bigger front sway bar helps a lot with the god awful body roll on the nose end of these cars, i track my yaris regularly and can say with confidence the trd sway bar alone is not enough, adding the feont sway bar will help the car rotate a little more ever so slightly so what i can now do when corner exiting now that i couldnt do before i give throttle input on corner exit, take my advise woth a grain of salt but upgrading the front sway bar makes a big inprovement to the car, it could also be all my other habdling mods as well

Thanks! I'll check in to it. First the Rear, then I will look at the Cusco!

I'm my notes are correct, the early hatch front bar (should have a blue dot on it) is a solid 24mm bar. The early sedan (purple dot) is a solid 23mm bar.
A stiffer front bar will help initial turn in, but ultimately makes the inside tire spin more, and the car understeer. Many of the B-Spec guys are running no front bar. I never liked the way the car felt with that setup on the H Prod car so we ran the smaller front bar. Around 2015 (I believe) they went to a tubular front bar and aluminum end links on the hatch, so that is what we ran on the later cars. All of the front bars are interchangeable.

Thanks J! The TRD rear bar arrived today. After installation and a little testing I will make a determination on the front!

yea i agree it will have a tendency to increase understeer, but again its probably just my setup, i have the cusco rs lsd and am running 205/45/16 slicks on the front so i guess if i were to still have dot tires and stock open differential i can see how it would increase understeer, one thing ice learned with racing fwd is you cannot force the front tires to do more than 1 thing, thats acceleration, braking and cornering all done on the front, tou start accelerating while cornering you will end up “pushing” out of the corner and vise versa, so i guess with dot tires and stock diff yes the front seay bar might do more harm than good, first install a limited slip, BIG tires up front, and .2 toe out alignment and you will see a benefit with cusco front sway bar

The car may feel better on entry with a big bar, more stable, but testing back to back with data will show lower apex speed and delayed acceleration - even with an LSD. Our first car had the Kazz LSD and we would still get inside tire spin with the sedan bar. A big front bar also starts to take away braking force if you are trying to trail brake, as the weight transfers and starts picking up that inside tire. Typically big bars are a bandaid for inadequate springs and shocks.

Sorry if this off topic, but has anyone else done this? I felt like it reduced my under steer, but I think it hits my muffler, not sure about the gas tank. I’ll see if I can stick a GoPro under there and go for a drive to find out.

https://www.yarisworld.com/forums/sh...ad.php?t=23911 You are lucky, some of our cars don't have that nut inside the frame to accept the bolt. I am considering drilling a hole in the back side to place one there. |

I am not dropping mine, the Yaris handles pretty well from the Factory, the rear TRD bar did improve stability/cornering a good bit. I am going for a Stock Look, after all my Sedan is a Daily Driver. However, I am investigating the 2ZR-FE engine swap. Looking at the possibility of having the correct VIN in the ECU, and keep the ignition inhibitor in place!

Do you have any specific information pertaining to the "Introduction"?
I see a lot of information out there pertaining to the same. Not sure what is pertinent and what is not! |
