Found a new bump stop option.

[FunctionSpec]

After 10 years of owning a Yaris lowered on moderate drop springs(Tanabe NF210) and COMPLETELY destroying 2 sets of bumpstops, I had to look at other options that would fit the Yaris and possibly last longer than OEM. Stumbled upon a set that's meant for the front struts of the VW Passat, Golf, Jetta, etc. Looked like it would fit, so I took the plunge and spent the measly 14 bucks and got some better-than-expected bump stops that fit perfectly for our application.

They are 70mm in length(2.75 inch) and fit right into the OEM bump stop mount. Made of some high quality, high density foam that is firm but dampens hard bumps well. Compared to the stock OEM bump stops, these look and feel 10 times better. These are also shorter than stock(about 1-1.25 inch shorter) so you don't have to trim them when installing lowering springs, just drop them in.

Made by FEBI, Part number 1K0412303B. Made in Germany.

Thanks for the info, this is really good to know as I'm not too sure how my stock bumps will look when i swap in Bilsteins.

Btw let me know how you find the B8's with lowering springs

[ern-diz]

Yes, as T said, very helpful, thank you.

I'd also be interested in your impression of the B8's with lowering springs. That's the setup I'm leaning towards when my OE shocks/struts go.

Probably all crumbled and broken into pieces like mine :laugh:

To answer everyones question about the Bilstein B8's on lowering springs, I only had them on for a week and put about 300 miles on them but so far they have been quite impressive. They are much firmer than stock but still quite comfortable for daily driving. Only time the ride gets harsh is over really broken up and bumpy roads. At low speed you can feel the bumps on the road more but at higher speeds it feels smooth. Cornering is much better, can take corners at faster speeds and stays flat. Feels stable over bumps. I feel very confident with this setup vs the stock shocks. Very happy with the B8's so far as I was a bit afraid it might be too stiff for daily driving. I am more of a "comfort-sport" type than a "street/track" type and these fit my needs quite well.

15k mile Bilstein update: the driver side front strut is now blown. Took apart the suspension to diagnose a loud clunk sound when turning right into driveways. Strut had zero rebound dampening and barely any compression dampening. You can hear a piece of metal rattling around when flipping the strut upside down. It also clunked when checking the shaft for play which is what I think caused the noise. Sucks I can't warranty these out since I bought them second hand. Oh well, bought another bilstein strut, hopefully they'll last but we'll see.

Oh and the new bumpstops still look good and are holding up very well so far.

Very interesting update, thank you. I sub'd to this thread for when the time comes to replace my factory shocks/struts. Happy to hear the bump stops are holding up but concerning to hear about the blown Bilstein. That's what I was thinking about going with. Hopefully it's just an abuse by previous owner thing and not indicative of the quality of those struts overall.

[FunctionSpec]

I think the previous owner did a couple track days with them. Looked like new when I bought them. His setup was a mild drop like mine, I have the Tanabe NF210 and he had RS*R springs. I think these broke much less than 15k miles because I've been dealing with the loud clunk for a couple months. Kind of disappointed these broke so quickly, there's a chunk of metal rattling in there when shaking the strut so it's definitely a manufacturer defect. Sucks as these are the only performance shocks readily available for the Yaris. I would still recommend them but I would definitely buy these NEW from an authorized seller so that you are protected by Bilstein's limited lifetime warranty.

[FunctionSpec]

Ok I think I found what caused the Bilsteins to prematurely break. After closer observation, I noticed the Bilsteins do not fully compress and that there's a 1.5 inch gap between the top of the strut body and bottom of the strut bearing. So a bumpstop that is 2.75in in length only has about 1.25in of up-travel before it bottoms out on the shock. If we estimate that the bumpstop compresses about 50% of it's length during a hard bump, that would be 1.38in of compression, which slightly goes past the amount of cushion these bumpstops provide. So really what that means, the bumpstops aren't protecting the shocks at a certain point and the shocks themselves are bottoming out during hard bumps.

I think the Bilsteins were designed to be used with the OEM bumpstops. There's a plastic spacer on the OEM bumpstop that limits up-travel by about 0.75 inch. Full length of the OEM is about 3.5in. The plastic spacer provides some insurance to protect the shock but knowing that the OEM bumpstops will crap out in a year or two has me worried. A crumbling bump stop doesn't provide much protection.

Quite the dilemma here. I need a bumpstop that's at max 3.5 inches long, any longer than that and the car is pretty much riding on the bumpstops. A bumpstop that isn't too "squishy" and is firm without compressing too much. The Febi bumpstops I have compresses quite easily the first 0.5 inch and then stiffens up. But I do have some time to figure out since these Bilsteins are on backorder for 5-7 weeks :cry:

[hichamaziz]

very helpful, thank you.

[tmontague]

wow, crazy stuff, thanks for the update. I'd probably stick with the Febi bumps, I'd be surprise if they compress to 50% easily as they will be progressive when being squished. Obviously this will depend on your roads and the spring rate of your springs but as you stated crumbling bumps offer virtually zero protection. This is one of the main benefits of coil overs as they are all one unit designed to work together so you avoid the issues of Frankenstein set ups with potential compatibility issues.

It is disappointing that the Tokiko Blues are no longer made and the back order of the B8's makes it seem like these are not a big seller and potentially will be discontinued down the road.

Hell I couldn't even get Fortune Auto to make custom spring rates on the rear for our car due to the lack of market for them. The only option was DC sports who were very willing to do virtually any spring rate I wanted.

[ern-diz]

I have B8 rear shocks in-hand and front struts on the way. About to try and buy these bump stops. Any update/feedback you have to offer would be greatly appreciated.

While we're at it and before I go off searching, does anyone have any top mount recommendations? Thinking something harder than KYB OEM but not full poly urethane either.

If you like the new stops you have just make a spacer so they engage early enough to prevent the strut from bottoming. With a cheap delrin cutting board and a hole saw you should be able to make a nice spacer.

Do you also suspect that's what's happening? I'm about to install B8's and based on this thread, am trying to decide if I should run the shorter stops or get new OEM size.

My Tein springs instructed to cut the OEM stops to a specific length. If the B8's are designed to replace OEM from a ride height perspective, then they should require shorter stops in a lowered application...

That replacement shock clearly (looking at your pic) is bottoming and destroying itself. Most of the Bilsteins I have used included a bump stop, which was slightly softer than a hockey puck. I would say this is a case of a replacement shock that "fits" but was not engineered specifically for that application.

Even if Bilstein went to trouble of building a Yaris specific strut it would not have been built around your Tein springs - and you can assume by the Tein instructions they expect you to be using OE struts.

I would use the OE stop or put a spacer in that lets the aftermarket bump stop do its job. You could still trim it a little, but it needs to protect the strut.

Gotcha, thanks for the input.

To clarify, I'm not the OP and that wasn't my picture. I'm just in a similar position where I'm running Tein S. Tech springs and am about to replace the OEM shocks/struts with the B8's. I'm happy to buy the FEBI stops, new OEM stops and use at full size or new OEM stops and cut. Just trying to find the ideal setup.

Since my B8 struts will be new in-box, I'm going to wait to see if a stop is included. If so, what size and go from there.

I installed the b8 with h&r sport springs 3 months ago and it didn't come with bump stop. Went with the febi bump stop like suggested in previous post. So far so good.

I'm also on b8's with tein stechs. I cut the factory bumpstop. All seems well so far

Mine were new in-box, all they came with were the nuts for the top of the shocks. No bumpstop included

[ern-diz]

Thanks for checking in. Between work and life, I haven't looked at Jegs or one of the other usual suspects for better than OEM bump stops and top mounts, so I haven't installed the B8's yet.

Worst case, I know I can go with a fresh set of OEM stops and mounts and just cut the stops like I did when I installed the springs.

[malibuguy]

FWIW...When I installed the MI springs (the way back like 8 years ago) i DIDNT cut my bumpstops and my reason was well better to have a little too much then not enough. Then I went to Tokico blues and still didnt cut them. About a year and 130~ thousand miles later I switched back to the stock springs and my oem bumps were still in fine shape and my shocks are just fine
And I thoroughly use my car ;)

Worst case, you're just losing a bit of travel over big bumps and making the stops work a little harder, right?

[hachi-roku_fan]

Does anyone know how the TRD set up is configured?

Is your question does a car equipped with TRD suspension utilize different bump stops than one with standard suspension? If so, the answer is they both use the same bump stops.

You answered my question! I figured the TRD set up would not require me to mod the oem bump stops

[ElMagnifico]

i dont know if this helps anyone but on my Tein Street Advance Z's they require the fronts to be cut to 60mm and the rear to remain unaltered. cutting the fronts down leaves the stiffer upper portion. i'm going to change them to a softer 58mm option i found.

[malibuguy]

Rediscovered this thread trying to pick out my next danpers.

Last year I changed out my stock front bumpstops for progressive Feal units. As even when I went back onto my stock springs I was still engaging the BSs too soon and it was causing the car to push mid corner on the road course.

So when I changed them out I also put ny MI springs back in to gain some spring rate.

The car is great. In fact in the 10 years ive owned it its never been better.

However...these Tokico blues are just a little firm on the low speed dampening and also allow too much lift which allows the car to roll pretty hard even with my big sway bars. Mind you this is on all seasons

i got my new bilstein b8 front and rear shock and tein s tech springs i cut the factory bump stop like tein recommended and it rides really good! gives you a lot more cinfidence in cornering now. i will say that the rear feels a little obessesivly stiff compared to front but overall im happy
