TRD rear sway bar installed

[TOLMACH]

(One more review)

Background: completely stock suspension (struts + springs). TRD rear sway bar installed (bought from TRDsparks)

Impressions: nice thing, definitely can feel its presence. Car became a bit sharper. Like this thing a lot. The thing is firm and sturdy - played with it a little before installation (I am kinda strong 215 lbs guy). Overall a great mod for 150 bucks.

Installation is very straightforward and easy. Also liked the trdsparks customer service - guys seem to be busting their asses (in a good sense).

I'm totally satisfied with mine as well. It tucks neatly up into the framework...



It's one of the best bang for the buck mods for a Yaris.

Especially considering UR became overpriced and this one is only 150 bucks

I have one sitting in the shed, waiting for the rest of the suspension parts to show up before I put it on...

My UR 23mm bar has been ordered just wiating for it to arrive. I would have gone TRD, but I plan to Auto-X the Yaris and wanted the larger bar, hopefully decrease the understeer. Looks good by the way!!

PS: Sparks Toyota (TRD Sparks) is less than an hour from my house, so I do plan on getting some TRD and stock parts from them!

I ended up getting the TRD but for the same reason: if you put on the TRD, it counts as a port option for SCCA AutoX--leaving you the option of adding a larger front bar. The larger bar, of course, will be coming from those beautiful folks at MI.

Not sure yet, but having a larger front bar has never been an issue on any of my previous FWD Auto-X and/or Road Race machines. Having the biggest rear bar I could find made the biggest difference, in fact the last car I built (Nissan) we removed the front bar completely. No more understeer and the LSD actually did it's job much better, with less camber needed!!

Glad to hear you enjoy it! I bought one for my 2012 (from TRDSparks) yesterday... Should be delivered tomorrow!

drop it now for ultimate handling

Thank you for the orders gents! We really appreciate the business and these cars are fun to drive when the suspension is modified! I have an 06 xB with highly modified suspension and have a blast everyday driving it.

^ Sparks, you should become a vendor again, this market is clearly still viable for you!

agreed. I got the 23mm bar also, It does improve understeer alot and that's with no camber adjustments. Right now I am very comfortable with the way it handles and consistantly getting top 10 pax out of 70 drivers. I am still debating on removing the front sway bar... I did some more neg camber in the front, feels great on the street, turns alot more sharper, will know how it handles this weekend at the event.

RacerB, I know you mentioned this before in the autocross threads, but were you planning to stay in HS or go to STF.. or are you doing NASA events, which are totally different?

Sorry to get off topic OP, looks great. What are your future plans with this car?

There is more then one OE front bar as well. We pulled off the stock 24mm bar and used a smaller 23mm we got from a 2007 sedan to help rotation. The 24mm has a blue dot, the 23mm has a purple dot.

I'm running the trd bar and would probably go to a bigger bar if I could do it over.
To add to this I pulled my front bar off last weekend to get an idea of how the car behaved with it missing, and it wasn't doom and gloom like I expected plus my times were something in the range of 2 seconds faster on a 60 second course this is also with running -.8 camber vs the normal -2.7 I usually run.

Going over my data I definitely lost lateral traction something like 0.05g but I was able to get on the gas so much earlier that the slight loss in lateral traction didn't matter. I wouldn't recommend this for anyone unless they were running much stiffer springs since body roll increased dramatically. Also I was having problems with rubbing as well as the car became quite a bit more loose and would oversteer on trail braking which is good for me since I don't left foot brake.

Right now the current plan is to prep the Yaris for HS with the local SCCA group (only auto-x game in town) and to continue building the PTE road race Celica for NASA. With my work commitments this year, haven't had much time for any Club activities, will be at CMS July 7th with NASA.

Closet car I can think of that I've raced to the Yaris, was my '74 Civic 1200, short wheelbase, FWD, and slightly tall for it's length. But we made that car work even with limited after market at the time and was one kick-ass little race car.

Understood, by the time we got to the point of disconnecting the front bar, we were running Koni inserts in custom housings with adjustible coil-overs and camber plates. Rear was set up with inverted Carreras with in-board lowering springs and 7/8" adjustible rear bar, also the tranny had a 4 puck clutch disk, 800 kg pressure plate and Phantom-Grip LSD unit. Car handled like a go-cart, but could barely outrun it's own shadow, still fun to race though!!
