ive run a few grades of their pads in my alfas and the pads were worth every over priced penny, but i havnt been able to justify it for the yaris...yet

Fair enough, I always used bendix in the past but they were ceramic and I read they are worse for light track use than semi metalics.

Need to take her out to really bed in the new brakes, but been stipping my wheels and getting them ready for a paint.

FWIW i remember something about not ever wanting a "flexible" brake line longer than 15? inches due to "swell" under pressure, and anything that long MUST be braided, with that said i have done up to 23 if memory serves on a 4wd conversion ford van

I see why that section in the rear is broken into hard line, rubber hose, hard line, then rubber hose again, to shorten the rubber hose length.

The slight swelling under pressure is what I was banking so you'd get less pressure in the rear for your rear disc conversion.

I'm keeping the hard line in between the two rubber hoses that I have, but I'll straighten the hardline, to extend it a bit and be able to tuck the rubber hose and not use the original bracket so it won't hit the frame.

chop the original bracket off and weld it on inside instead of the top, theres a thread on here I read where they did this. Not sure if they got new hardlines made.

That's exactly what I had planned on doing, but my buddy (who made the plate for my disc conversion) can't make it to help me this weekend to install the disc conversion. He has a welder, but he lives an hour away, I'm too lazy to grab it during the weekday. I'll probably end up just riveting the brackets in place.

I bought the stock hard lines supposedly for the Yaris SE, PN 47324-52100 & 47323-52110. But having a shop make them would probably have been cheaper.
Well, at least I can use them to mock up about where to put the rear most brackets before I straighten them out a bit to stretch them to reach the bracket that will be relocated.

Are the TRD springs that much softer than the Tein's? Or I guess it's just the angle of your pic that makes it look closer to the frame vs mine?

the tein are softer but also its the Flex Z so I I can shorten front and rear shock absorbers to match the ride height, So yeah the shocks are shorter even than my short trd shocks which I believe are shorter than stock as well.

Honestly there is a guy selling a set of cusco coilovers second hand and i kinda wanna get them, the fronts are stiffer but the rears are the same as tein, I could sell the flexz set then maybe, would have some decent track shocks and the tiens for the road. Just need to get my guy certified and plated for adjustables. If I buy the cusco i may even just swap the springs depending on how worn they are. Also do you run spacers? Plan to buy some so i can stop slight inner tire rub, Im thinking 3-5mm will do they only just touch full lock.

flex zs are stiffer than s tech springs, the flex zs are 4ksprings front and rear

i hate the fact you can find this stuff used.......

If it was not used I would never be able to afford it to be honest and I search a LOT and I find almost nothing, I just always share it when I do find something haha

something thats been on my mind alot latey is the gen1 scion has a HUGE following..and alot of the stuf is the same from/for the yaris...are the struts?..i see them pop up all the time reasonably priced..id bet the spring rates arnt the same due to a lil extra weight but thats not the concern

Looking at the pics from RockAuto, the struts are different. The steering knuckle's mounting holes for the 1st GEN xB angles out, while the Yaris' are vertical.

I don't know what your goal is? Were you planning on using the xB1's strut in your Yaris or vise versa?

i find performance XB parts pretty much every week and reasonably priced and useualy reasonably local......meanwhile finding performance yaris stuff means looking outside the country and bending over for shipping costs

so yeah im looking for alternatives

If you're trying to put xB1 suspension on the Yaris, you might have to put xB1 steering knuckles on the Yaris as well. I don't know how much you'd save, you'd need the steering knuckles, bearings, and hubs. And I don't know if the xB1 knuckles would work on the Yaris.

I'm extremely happy with my Tein S. Tech lowering springs and Bilstein B8 struts combo. And I've still yet to replace the rear shocks, they're still stock.
Some have used the Megan Racing lowering springs with the Bilstein B8 and have been very happy. The Megan Racing springs are softer than the Tein's.

Do you plan to track your car? If you do, check out what the regulations are.

nah no track time but i do find myself up in the hill hooning HARD and the stock suspension is pushed to its limits, the kicker is i need something progressive rate and idealy an adjustable shock/strut so i can dial it in to my driving style...sure at the end of the day its not my alfa alfetta sprint gt or GTV6 but id like to get it dialed in further...funny enough im not looking to lower it in the slightest, specificaly because of those mountain roads some of the dips allready tap the chins on the ground...so losing clearance is NOT an option

gotta be able to "stick" the corners even if theres bumps n dips..

Are you still on stock suspension?
The Tein's lowering springs are progressive and the 1.9in drop makes a huge difference. I remember before I installed the lowering springs, I had a lot of body roll. Now I feel like on rails.
Before I got the Bilstein B8 struts, I thought about getting the Tein's Flex Z, but now, I'm content with my suspension. I think I'd just add rear sway bar, get B8 shocks for the rear, and maybe front tower bar.

cant lower.....roads wont allow it ..chins allready take hits as it is and im not talkin about just driveways but actual dips in the back roads

I am back using the TRS sportivo suspension currently, thats pretty close to stock height and rides nice, the springs could work good for you and are still around, little stiffer and tiny bit lower? I guess tho you have snow to deal with.

eh snows not the issue to be honest..and the snow tires are as tall as i can fit

its the roads i go burn up that are the issue....the super fun twistys have alot of odd dips n such, but were talkin twisty mountain roads that run like a rollercoaster...so youll hit hard dips and the chins will scrape....im at stock hight ..stiffer springs would help a little..so a tiny drop with some stiff would be fine
