Stiffer Front Sway Bar??

[invader166]

Thanks for the reply everyone!

My goal is the reduce body roll and under-steer through corners as much as I can without using coil-overs since this is my daily driver. I don't plan on using my car for any competitions, events or track days yet. ...at least not for a long, long time.

(Someday I hope to. It's been a dream of mine for a while, but for now I have go-karts. )

I haven't done any major suspension work at the moment. (does a front strut bar count?) For now, I'm just weighing in on my options and bouncing some ideas around, hence my question about a larger front sway-bar.

So far, I'm planning on installing a set of MI lowering springs along with new aftermarket shocks and struts. I also have an 22mm adjustable rear sway-bar that I'll be installing during that job. I'm also exploring the possibility of using wheel spacers but I'm hesitant about that since it's a DD vehicle.

@MUSKOKA800: Interesting idea with disconnecting an end-link. Now I'm curious to find out if that really would improve things. (or make them worse, since I know Toyota doesn't like to add things that increase the cost of their vehicles unless they have no other choice lol)

@CoryM Awesome!! I had no idea someone was actually using a set-up like that competitively. I'd love to see if it really does make an improvement on your run times.

Also, holy smokes!!! That photo is totally crazy! You're on 3 wheels!! Is there no way you can get some down-force on that car?!

I will keep you posted as I dial in the swaybar, and try different things. Rear swaybar is the first handling mod you want to do. I only run the TRD bar because then I can use two swaybars in Stock class. If you want to run in STF class any swaybar is legal, and stiffer springs is the next step. They will reduce the roll, and not cause any more understeer. The front swaybar is literally the last part I've put on my car in an attempt to make it handle better. It's not something you should go for first as it does have some negative effects (understeer).

There's no reason to wait to race your car... I AutoXed mine totally stock except for alignment for 2yrs and had a lot of fun. Bring yours out and have fun; you won't find a better way to improve your driving and learn about what mods actually work. It's fairly cheap too.

Three wheels (tripodding) is pretty common at autoX. It's due to the rear swaybar. Downforce isn't viable as the speeds aren't high enough. Probably only doing 70kph in that picture.

Disconnecting the swaybar does work for some cars (especially in the rain). I'm almost certain that the stock Yaris springs are too soft for it to be faster in any situation though. Typically you need stiffer springs to get away with it.

Cheers.
